1. Applications and features
1. The 1MB frameless spindle motor
1MB frameless spindle motors are used as direct drives in motor spindles. Themotor spindle acquires a high degree of rigidity by placing the motor betweenthe main spindle bearings. This means that in lathes, for example, only onedrive is needed for main spindle and C-axis operation.
Motor spindles are used for lathing, milling and grinding operations in machinetools, transfer facilities, finishing centers and other special machinery.
Figure 1.1 shows the parts of an AC main spindle drive with frameless spindlemotor.
Motor spindle
Figure 1.1: Parts of the AC main spindle drive with frameless spindle motor
The motor spindle is made up of the spindle with housing, bearings, framelessspindle motor with cooling and motor feedback.
Determining which type of bearing and which type of lubrication are to be used,and the extent of bearing stress all depend upon how the motor spindle is used,and is the responsibility of the manufacturer of the spindle.
How the frameless spindle motor influences the contruction of the motorspindle is described in this document.

Motor feedback The motor feedback measures rotor position and signals it to the drive for thepurpose of controlling RPM and spindle position. It is integrated into the motorspindle as an independent sub-assembly.
Together with an INDRAMAT main spindle drive, the motor spindle offersmechanical power and torque as outlined in the characteristics curves of themotor-drive combination. See documentation "AC main spindle drives withcontrolled 1MB frameless spindle motors, selection guides", doc. no. 209-0042-4118.

Figure 1.2: Typical characteristics curves of a 1MB frameless spindle motor
The frameless spindle motor has a high power density because of the liquid-cooled stator. The coolant absorbs the dissipated heat of the stator and mostof the heat dissipated by the rotor. The dissipated heat is then transferred inthe cooler to a primary heat-exchanging unit.

1. Applications and features
Design The frameless spindle motors are liquid-cooled threephase asynchronousmotors with cage rotors. They consist of a stator with cooling jacket and a rotorwith step interference fit. The motor size is named after the outside diameter,D
n, of the laminated core.
There is a spiral groove on the cooling jacket. The coolant is conducted overit between spindle housing and cooling jacket.
The step interference fit on the rotor is a friction-locked interference fit. Itmakes it possible to easily mount or dismount the rotor. Step interference fitscause no tension which could interfere with the running smoothness of thespindle. They also increase the rigidity of the spindle.

Figure 2.1: Mounting the rotor, and operating principle of the step interference fit
The rotor consists of a sleeve and a laminated core with balancing ringslocated on the front. The spindle has two fitting surfaces arranged next to eachother. These have slightly graduated diameters (ø D1 > ø D2). Rotor undspindle are frictionally engaged by the step interference fit. The graduatedfitting surfaces align the mounted rotor to the spindle. They are needed so thatthe rotor can be dismounted without damage.
The spindle construction with respect to the step interference fit must correspondto the guidelines outlined in "Technical Data - constructing the motor spindle".
The rotor is mounted by shrinkfitting it onto the spindle. The oil under pressureprocess is used when dismounting.
The rotor is heated up to approximately 200 °C prior to mounting. The materialexpansion means that fittings expand to fit diameters D1and D2. Rotor andspindle can be joined without force of pressure. The rotor can be dressed toits final dimensions once it has cooled down.
Oil under pressure is injected into the step interference fit for dismounting. Thiscreates an axial force with which the rotor can slide off the spindle as soon asthere is a separating oil film between the fitting surfaces to separate them. Thestep interference fit starts to loosen at diameter D1 first. The O-ring keeps theoil from running out.
The steps for mounting and dismounting are outined in detail in Section 14 ofthis documentation (Mounting Guidelines).

2. Technical information
After mounting, the rotor is balanced to the necessary vibration severity grade(DIN VDE 0530, section 14). Threaded pins are radially screwed into thecircumference of the balancing ring to achieve equilibrium of the rotor. Thethreaded pins are additionally bonded into place. No material may be removedfrom the balancing ring.

Figure 2.2: Mounting the stator
The stator is made up of a laminated core with end windings located on thefront, and the cooling jacket. The outside diameter of the cooling jacket isstepped. As a result, the ends of the stator are called thick and thin stator ends.
Construct the mounting drill hole in the spindle housing as per the data in thesection entitled "Technical Data - Constructing the Motor Spindle".
The stator is axially mounted in the motor spindle at either the thick or thin endof the stator. It must be secured against movement. Windings for axialmounting and drill holes for cylindrical pins (not with 1MB 140) are fixed to thefront as protection against torsion.
There must be a clearance between stator and spindle housing of at least 1mmon the end opposite the stator end. The stator can thus expand in length. Thisexpansion of length is caused by the stator heating up while the motor spindleis operating.

Securing the stator
13• DOK-MOTOR*-1MB********-PRJ1-EN-E1,44 • 03.97
2. Technical information
The stator is light in weight and small in size. It, therefore, does not achieveits final flexural strength until it has been built into the spindle housing.
The spiralled slot worked into the cooling jacket creates a cooling channeltogether with the spindle housing. This channel is sealed at both ends with anO-ring. There is a wraparound leakage groove between the O-rings. A holemust be drilled at the lowest point of the spindle housing for any leaking coolantto be able to run off.
The cooling jacket is made of aluminum and is protected against corrosion bya hard coat surface. The spindle housing must also protected againstcorrosion. A suitable coolant or coolant additive can be used for this purpose.
For additional information on dimensions and selecting the proper coolingmode, see "Liquid cooling of INDRAMAT drives; dimensioning, selection",doc. no. 209-0042-4123.
The power terminal is brought out through one of the end windings of thestators. There is also at least one NTC thermistor in this end winding. Itmeasures the winding temperature through the drive.
The power terminal and the NTC thermistor are conducted together as a motorwinding through a tube. Depending upon how it is ordered, the motor windingcan be located at either the thick or thin end of the stator.
When bringing the cable through the spindle housing, note the following:
• the bending radius of the motor winding must not be less than outlined (seesection "Technical data"), and,
• the edges of the drill hole in the spindle housing must be rounded off.

2.3. Motor feedback
The drive must be able to detect spindle position in order to control spindlespeed or when positioning the spindle. The motor feedback is used for thispurpose.
The high-resolution main spindle position encoder from INDRAMAT functionsas a motor feedback for frameless spindle motors. It is made up of a measuringwheel and a non-contact sensor. The measuring wheel is mounted on thespindle, the sensor on the spindle housing.
There are three measuring wheel sizes available for the different framelessspindle motor sizes.

2.4. Precision
The precision of a motor spindle depends on its mechanical design and thecontrol technology.
The degree of motor spindle precision which can be achieved is affected bythe rigidity of the housing, bearings and spindle as well as by its operatingprecision. The operating precision in both axial and radial directions isdependent on the lay-out of the bearings and the accuracy of this lay-out.These demands are met by an appropriate spindle construction.
The operating precision of the spindle depends upon the control quality of thedrive systems motor, motor feedback and drive. The rotational positionaccuracy of the spindle is determined by how accurately the drive can read thespindle position and the absolute position accuracy of the motor feedback.
• The drive reads the spindle position signal received from the high-resolutionmain spindle position encoder with an accuracy of up to 1/4000000 th of arevolution.
• The size of the measuring wheel and the accuracy with which it is mounteddetermine the precision with which the absolute position can be measured.
For further information see "High-resolution main spindle position encoder;Project planning manual", doc. no.: 209-0042-4119.
The position accuracy of the spindle, so important to C-axis operation,depends upon the resolution of spindle position and the type and resolution ofthe velocity command value. The velocity command value from the NC controlunit can be transmitted to the drive in three different ways:
• analog, +/- 10V maximum
• digital, 16 bit parallel
• SERCOS-interface
One performance feature of these three modes of velocity command valueentry is a very broad RPM range -- from minimum RPM, 0.0005 rpm, tomaximum RPM.
Analog, +/- 10V maximumThis interface is equipped with two differential inputs. The resolution can beset with parameters.
Digital, 16 bit parallelGuarantees high command value accuracy with small command values andlong transmission paths.
SERCOS-interfaceThe fiber optics cable interface, SERCOS interface, offers the most powerfulmode of command value entry. It transmits, in addition to the command value(position, RPM or torque command values), the actual values and drivediagnostics.

2.5. Heat dissipation of the frameless spindle motor
The heat dissipated by the frameless spindle motor in the motor spindle isprimarily eliminated by a liquid coolant. The end shields and the rotatingspindle also help dissipate heat.

Heat carried offby coolant
Coolantfeed
Figure 2.4: Heat flow in the motor spindle caused by the frameless spindle motor
2.5.1 Heat dissipation of the stator
The frameless spindle motor has been designed in such a way that most of theheat is produced by the stator. The coolant flowing around the cooling jacketof the stator very effectively absorbs this heat. In addition, the coolant alsomaintains uniform temperature in the spindle housing.
The dimensions for a liquid cooling system can be found in the technical dataof the relevant frameless spindle motor. The document "Liquid cooling inINDRAMAT drives; dimensioning, selection guides", doc. no.: 209-0042-4123, offers detailed information on dimensioning and the selection of anappropriate cooling system.
2.5.2 Heat dissipation of the rotor
Approximately one third of the heat dissipated by the frameless spindle motoris produced in the rotor. Most of this heat is transferred to the stator via an airgap. A small portion of the heat is dissipated over the spindle, bearings andthe end shield. The extent of this heat flow is dependent upon the type and thevolume of the materials over which the heat flows.

Figure 2.5: An example of a calculated temperature curve
The temperature curve is individual for every spindle and motortype. The temperature curve depicted in Figure 2.5 should not begenerally applied. It only serves as an example for similar designs!
The increase in bearing temperature caused by the heat transfer dependsupon
• the rate of utilization of the motor (heat entry), and,
• the mechanical construction (heat transfer).
Temperature distribution depends on the conditions and can be determined.A heat transfer calculation, the FEM method (finite element calculation), isused.
The amount of heat transferred by a motor spindle with a 1MB 310D framelessspindle motor was calculated below. The curve of the temperature withnominal power output for a spindle with drill hole was calculated.

By taking specific structural measures, it is further possible to keep heat awayfrom the bearings. Figure 2.6 depicts an example of such a structural change.Liquid-cooled cuffs are used. These bring about additional cooling by beingclose to rotor and spindle. Depending upon the fluid circulation system of themotor spindle, be sure there is no drop in pressure or flow of coolant!

2. Technical information
FAKÜHLRING
FAFLMANSCH
Figure 2.6: Liquid-cooled cuffs mounted close to the rotor
The fittings and tolerances make it possible to radially pre-stress the bearingsfor the shaft seat and drill hole of the housing.
A temperature gradient between the inside and outside ring of the spindlebearing increases this pre-stressing because of the varying degrees ofthermal expansion. This increases frictional losses which additionally heats upthe bearings. An overheating of the spindle bearings can cause damage.
When designing the motor spindle it is, therefore, also necessary to note asmall temperature difference in the spindle bearing.
Alternatively, structural changes can additionally transfer heat to the outsidering of the bearing.
Cooling rings, as depicted in Figure 2.7, transfer some of the heat producedby the rotor directly to the end shield. This heats up the outside ring of thebearings and the temperature gradient drops.

2.6.1 Ground terminals
The 1MB motor is grounded on the drive via the motor power cable. Theground terminal on the stator of the motor spindle must be laid out as shownin the dimensional sheet. See section "Technical data" of the relevantframeless spindle motor.
The diameter of the ground terminal line corresponds to the minimumconductor diameter of the relevant 1MB motor as listed in the "Technical data".
20• DOK-MOTOR*-1MB********-PRJ1-EN-E1,44 • 03.97
2.6.2 Power terminal
The power terminals of the frameless spindle motor can be:
• terminal connections (junction box), or,
• plug-in connections (flange socket).
The motor winding of the stator is 1.5 meters long. This winding is enclosedin a protective tubing and is made up of three power conductors -- six powerconductors in a motor with selectable windings -- and two wire pairs for theNTC thermistor in the end winding.
The diameters of the power conductors of the motor winding depend on therated current of the motor. Diameters of 10, 16, 25 or 35 mm2 are available.Thediameter of the wire pair for the motor NTC thermistor connection is 1.5mm2.
The motor winding is connected inside the motor. The insulation of the motorwinding is, therefore, designed for temperatures higher than those found in themotor power cable (connection between motor spindle and drive). Theminimum core diameter of the motor power cable listed in the section"Technical data" is generally different from the diameter of the power conductorof the motor winding.
The bending radii of the motor winding are listed in the dimensional data of therelevant frameless spindle motor (see "Technical data").
A junction box with terminal connections is used to connect the motor windingof the stator to the motor power cable. The junction box is mounted to thespindle housing. It must be equipped with a three or six pin terminal board forthe power terminal, and a terminal strip with four clamping points for the NTCthermistor (see Figure 2.9). The standards as depicted in Figure 2.10 must bemaintained for the terminal connections to be properly implemented!

1) Data relates to S1 operation of a motor on KDA/TDA drive (Uneff = 220V) or RAC(Uneff = 380V). The S1 data of other motor-drive combinations can be derived from therelevant characteristics curves.
2) The motors are not suited for direct mains connection.3) Inductance of the mounted motor spindle at 20° C., measured between the power
conductors with f~ = 1 kHz.4) Data relates to water-based coolant. Should other coolants be used (e.g., oil), recalculate
data or see flow diagram.

Cooling jacket material: Aluminum, hard coat surface O-ring: Viton
1) Data relates to S1 operation of a motor on KDA/TDA drive (Uneff
= 220V) or RAC(U
neff= 380V). The S1 data of other motor-drive combinations can be derived from the
relevant characteristics curves.2) The motors are not suited for direct mains connection.3) Inductance of the mounted motor spindle at 20°C, measured between the power
conductors with f~ = 1 kHz.4) Data relates to water-based coolant. Should other coolants be used (e.g., oil), recalculate
data or see flow diagram.

1) Data relates to S1 operation of a motor on KDA/TDA drive (Uneff = 220V) or RAC(Uneff = 380V). The S1 data of other motor-drive combinations can be derived from therelevant characteristics curves.
2) The motors are not suited for direct mains connection.3) Inductance of the mounted motor spindle at 20°C, measured between the power
conductors with f~ = 1 kHz.4) Data relates to water-based coolant. Should other coolants be used (e.g., oil), recalculate
data or see flow diagram.

14. Mounting Guidelines
14.1. General information
These guidelines describe:
• how the rotor is mounted to the spindle,
• how the rotor should be removed from the spindle,
• how the stator is built into the spindle housing and electrically connected,
• how to check the motor spindle electrical connections, and,
• how to remove the stator from the spindle housing.
Carefully adhering to the steps described here will ensure:
• the faultless and safe mounting and removal of the parts and
• the proper functioning of the frameless spindle motor.
The instructions specified and explained in the safety guidelines must beadhered to. They help to prevent accidents and damage to materials resultingfrom improper handling.
Section 14.2 outlines general safety guidleines.
Additionally, there are special safety guidelines listed in the mounting guidelines.These will be found there where increased danger is given or could possiblyoccur.
The safety guidelines are emphasized with the use of the following symbols:

The procedures for mounting and removing the various components is alwaysthe same. The procedure can vary, however, depending upon the structure ofthe spindle and its housing. These guidelines are, therefore, simply general innature and must be adapted to suite the given demands. The mountingguidelines of the builder of the spindle and its housing are binding and havepriority over the procedure described here.
The procedures depicted below offer an overview of the individual steps.

1)With some motor types, the rotor will be supplied "dressed". This means thatIndramat has already finished the rotor to its required final dimension. Thus,the final step of "dressing the rotor to its final dimension" does not, in this case,apply.
The rotors that are supplied in this completed state have a sticker indicatingthis on them. For further information, see Section 16.1 "State of Delivery".

14. Mounting Guidelines
14.2 General Safety Guidelines
General safety guidelines are outlined in this section. These must always benoted and followed.
Use only manually-operated oil pumps when removing the rotor from thespindle. Manually-operated oil pumps guarantee that the oil pressure willimmediately drop to 0 bar in the event of leaks in the interference fit, thewindings or the pump system. For safety reasons, the oil pump must beadditionally equipped with a safety valve which prevents the oil pressure risingabove 1500 bar.
The threaded pins in the rotor must be secured to keep them from looseningduring operation and thereby endangering both machinery and personnel.Bond the threaded pins with LOCTITE for this purpose. See bonding guidelinesin section 14.4.
The appropriate safety clothing must be worn when mounting. There is, inparticular, the danger of burns when shrinking the rotor onto the spindle. Heat-resistant clothing must be worn.
Follow the accident prevention guidelines, "Electrical plants and operationalequipment", (VBG 4). Prior to working on live parts in plants and on equipment,disconnect all voltage and make sure it cannot be re-connected. The plantsand equipment must be checked, prior to the initial start-up, by a qualifiedelectrician, or under the supervision of a qualified electrician.
The user is responsible for proper grounding. Protective measures must betaken against direct and indirect contact to prevent accidents which can becaused by contact with live parts. See DIN VDE 0100, section 410, for details.
Transportation and handling guidelines must be followed (Section 15: "Storage,transportation and handling").

Explanations Work fixture for mounting the rotor:The fixture must be heat-resistant up to at least 200 °C. It must also be ableto support the weight of both the rotor and spindle. In addition, it must createa level and horizontal surface for the rotor. The following illustrates anexample.
Figure 14.3: An example of a work fixture for mounting the rotor
Manually-operated oil pump and accessories:Oil pressure equals 1500 bar with a safety valve. A connective winding sizeof the high-pressure duct is M6 or M4x0.5 (depending upon type of rotor).
Oil pumps and accessories can usually be obtained from the manufacturersof roller bearings.
Clamping device for mounting spindle-rotor:Should the spindle be deformed once the rotor has been fitted by shrinking,then a clamping device is also needed to correct this deformation. This devicemust firmly hold the rotor into place on the spindle and prevent any axialmovement of the rotor. Figure 17.12 illustrates an example.
Arresting device:When removing the rotor from the spindle it can suddently slide off of thespindle. The spindle must therefore be equipped with an arresting device.Figure 17.14 illustrates an example. The dimensions of the arresting devicemust be noted (see Figure 17.15).

General information
14.4 Securing the screws with LOCTITE 1)
LOCTITE is a plastic bonding agent. It is applied in liquid form to the parts tobe mounted. The agent retains its liquid form as long as it has air contact. Onlyafter the individual parts have been mounted does it change from its liquidstate to a solid plastic state. This chemical transformation takes place becauseof the lack of oxygen and the contact with metal. A form-fitting bond is created.It is resistant to shock and vibrations.
Setting activator 7649 cuts down the setting time of the bonding agent.
LOCTITE 620 is heat-resistant up to 200 °C, LOCTITE 243 up to 150 °C.
Procedure:
1. Remove metal shavings and dirt from threaded hole and screw or threadedpin.
2. Remove all oil, grease and dirt from the threaded hole and screw/threadedpin with LOCTITE quick cleaner 7061. All surfaces must be absolutely freeof rust.
3. Spray LOCTITE activator into threaded hole and let dry.
4. Wet the same threaded hole uniformly and thinly with LOCTITE over itsentire surface.
5. Screw in matching screw/threaded pin.
6. Allow to set. Note setting time as illustrated in Figure 17.4.
Securing screw connections with LOCTITE in tapped blind holes:The bonding agent must be applied in the threaded hole and not to the screws.This prevents any air from pressing the agent out once the screw or threadedpin are screwed in.
14. Mounting Guidelines
Bonding
Note: The values are based on setting at room temperature. Setting time can be shortened by applying heat.
Completely Partially set Partially set set without activator with activator 7649
LOCTITE 243 ≈ 12 h 15 to 30 minutes 10 to 20 minutes
LOCTITE 620 ≈ 24 h 1 to 2 hours 15 to 30 minutes
Figure 14.4: Setting times for LOCTITE
The connection is undone by removing the screw or the threaded pin withthe use of a conventional key.
LOCTITE 620 has a breakaway torque of 20-45 Nm, for LOCTITE 243 it is14-34 Nm (per DIN 54 454). Blowing hot air at the screwed joint reduces thebreakaway torque.
After the screw or threaded pin has been removed, it is necessary to removeany bonding agent residue from the hole (e.g., by shaving the thread).

14.5.2 Prior to mounting
Mounting should take place in a dry and dust-free environment. The followingmeasures should first be taken:
• Check to see whether all parts which were to be delivered have beendelivered.
• Visually check the rotor for any damage.
• Mount the rating plate in a conspicuous position on the spindle housing.
• Make sure that the bevels and edges of the press fits of the spindle are freeof burrs, remove these if necessary.
• Inside diameter of the rotor, oil connection drill holes and press fits on thespindle must be thoroughly free of dirt, dust and metal shavings.
122• DOK-MOTOR*-1MB********-PRJ1-EN-E1,44 • 03.97
14. Mounting Guidelines

The spindle usually slides into its end position without requiring additionalforce (final stop on spindle). If it does not slide into its end stop by virtue of itsown weight, then the spindle can be forced into place in the rotor with no morethan 500 N (the force equal to the body weight of the mechanic).

14.5.3 Shrinkfitting the rotor onto the spindle
1. Heat up rotor in the warming cupboard to at least 180 °C, but no more than200 °C.
If the rotor is not heated up to at least 180 °C, the spindle will getstuck in the rotor during the shrinkfitting process before reachingits final position.
Note!
The rotor is hot! There is the risk of injury by burning!
Wear protective clothing!
2. Place rotor into the ready work fixture. The O-ring must be at the top!3. Pick spindle up and quickly slide it into the rotor.
124• DOK-MOTOR*-1MB********-PRJ1-EN-E1,44 • 03.97
4. Let rotor and spindle cool to room temperature.
5. Check whether the rotor has properly shrunk onto the spindle.
• Visually check whether the spindle is in its final position in the rotor.
• Check the concentricity of the spindle.Check whether the concentricity of the spindle is still as good as it was priorto shrinkfitting.
If concentricity has deteriorated, then the spindle is slightly deformed. Thisdeformation is caused by stress which can occur in the step interferencefit during cooling.
If the spindle is not in its final position, and the necessaryconcentricity has not been achieved, then the remedial steps asdescribed in section 14.5.6 must be taken.
14. Mounting Guidelines
6. Use the threaded pins to close the pressure oil connections in the rotor. Thismeans screwing the threaded pins in all the way and securing them againstrotation with LOCITE 620. (For bonding guidelines see section 14.4). Thethreaded pins must be bonded into place in such a way that they completelyseal the connections against any oil pressure that might occur.
14.5.4 Dressing the rotor to its final dimensions
If the rotor is delivered "dressed", then no further finishing isrequired or should be performed. The rotor already has itsrequired outside diameter (final dimension).
There is a sticker indicating that the rotor is dressed on those rotors suppliedin this state.
In the event of doubt, measure the outside diameter of the rotor and comparethe measured dimension with the relevant data on the data sheet.

Once the rotor and the spindle are firmly attached, then the outside diameterof the rotor within the zone of the laminated core can be dressed dry (withoutcoolant or cutting liquid). The final dimensions of the outside diameter willdepend upon the motor type. These are listed in the relevant data (see section"Technical data").
When dressing, make sure that the maximum deviation of concentricity tobearing seats A and B does not exceed the prescribed value.
The values (maximum deviation of concentricity, surface roughness) for thevarious motor types are listed in the relevant data sheets.
Do not grind and do not dress rotor when it is wet!
No material may be removed from the short circuit rings or thebalancing rings!
14. Mounting Guidelines
If too much material is machined off, this will alter the characteristics curvesof the drives.

14.5.5 Balancing the rotor
The rotor must be balanced with the spindle to achieve the desired vibrationseverity grade of the spindle. There are balancing rings on the front of the rotor.These have tapped holes. Threaded pins should be screwed in, as needed,for balancing. The table in Figure 17.11 lists the threaded pins generallysupplied.
The vibration severity grade needed depends on the finishing accuracy of themotor spindle. The accuracy is determined by the builder of the motor spindle.
Remove no material from the balancing rings when balancingthe the spindle!
Figure 14.10: Balancing by inserting threaded pins
The threaded pins can be inserted to a greater or lesser degree,depending upon the mass equilibrium required. They may not,however, protrude out of the balancing ring! It is not necessary tocompletely insert them!
Make sure that the threaded pins cannot loosen themselves bybonding them with LOCTITE 620! See section 14.4. for bondingguidelines. Note setting times with activator! Do not use activator,if not necessary.

Procedure:
1. Let rotor and spindle cool down.
2. Seal one of the two pressure oil connections on the rotor with a threaded pin.Screw in the threaded pin all the way and prevent it from turning withLOCTITE 620. (See section 14.4 for bonding guidelines.) The threaded pinmust be bonded in such a way that it is completely sealed against any oilpressure.
3. Force the rotor off of the spindle with the help of the pressure oil (asdescribed in section 14.6 "Removing rotor from spindle").
4. Check the tolerances of the press fits.
5. Remove burrs from the inside diameter of the rotor and at the interferencefits ød1 and ød2 of the spindle.

Slowly increase oil pressure until oil begins to leak out of the coil end of theinterference interface.
6. Eliminate all pressure from the oil pump, supply lines and interference fit.
7. Open both pressure oil connections.
8. Bring spindle with clamping device into a vertical position. Using compressedair, force the oil out of the step interference fit (see Figure 17.13).
9. Let oil completely run out of the step interference fit.
10.Seal both pressure oil connections with threaded pins and secure themwith LOCTITE 620.

14.6 Removing the rotor from the spindle
In the following cases it may be necessary to remove the rotor:
• damage to the bearings on the spindle
• rotor damage
• mounting error
14. Mounting Guidelines
The angular position of the rotor must be marked on the spindlebefore removing.
It is necessary to shrinkfit the rotor onto the same spindle, at the positionmarked, when re-mounting. This maintains the concentricity tolerance of theoutside rotor diameter to the bearing seats.
Procedure:
1. Mark the angular position of the rotor on the spindle.
2. Open one pressure oil connection.
The second connection must remain closed. Secure it, if necessary, withone of the threaded pins. This means that the threaded pins must becompletely bonded and locked against rotation with LOCTITE 620. (Seesection 14.4 for bonding guidelines.) Bond the threaded pin in such a waythat it completely seals the connection against any oil pressure.
3. Mount the end stop (example in Figure 17.14). Note the mounting dimensions(A) for it.

14.7.3 Mounting the stator into the spindle housing
There are tapped holes on both ends of the stator for mounting the stator intothe spindle housing.
Note: The basic procedure for mounting the stator in the housing is always thesame. It can, however, on occasion deviate from the procedure describedhere, depending entirely upon the construction of the spindle housing. Thefollowing describes how the stator is mounted to the back side of the endshield.
Procedure:
1. Lubricate the O-rings.
2. Insert O-rings (position 1; per stator accessory list) into the grooves locatedfurrther inside (coolant seal). Do not twist the O-rings! Keep all surfacesclean!
3. Insert O-rings (position 2; per stator accessory list) into the grooves furtheroutside (leakage groove). Do not twist the O-rings! Keep all surfaces clean!
It can be mounted to either the thick or thin end of the stator, but notto both!

14.7.4 Checking the seal-tightness of the O-rings
Once the stator has been mounted, the seal-tightness of the O-rings shouldbe checked.
Procedure:
1. Fill the coolant groove between the cooling jacket and spindle housing withcoolant.
2. Seal one of the coolant connections in the spindle housing with a screw plug.
3. Connect a pump with pressure indicator and pressure regulator for thecoolant to the second connection.
4. Position the spindle housing in such a way that the drain is now at the lowestpoint (bottom).
5. Pump in the coolant and slowly increase pressure from zero to six bar.
6.Once six bar have been reached, watch the drain for ten minutes to seewhether any coolant is leaking.

14.7.5 Connecting the electrical supply leads of the stator
There is a 1.5 m motor winding attached to the stator at delivery. It is encasedin a protective tube and is made up of:
• three power conductors (labelled U,V and W),
• and, two wire pairs for the two NTC thermistors in the end winding.
Only one of the two thermistors is connected to the drive. The other is only areserve. Its functioning is not guaranteed.
Before connecting the NTC thermistor, check to see whether it is working. Theresistance of the thermistor is measured at room temperature with anohmmeter for this purpose. If the value measured equals 30-50 KΩ, then thethermistor is operational and can be used.
All lines are connected either in a flange socket (INDRAMAT IN 192) or ajunction box. Both flange socket and junction box must be mounted directly tothe spindle housing.
The terminal diagrams are documented in "Electrical connections of the mainspindle drives; Project planning manual" (doc. no. 209-0042-4111). Flangesocket, or junction boxes must be directly mounted to the spindle housing.
When routing the motor winding to the junction box or flangesocket, do not permit the bending radius to fall below the permissiblevalue!
The edges of the through-holes may not be sharp!
The permissible bending radius is dependent upon the diameter of the motorwinding of the motor type. The radii are listed in the data sheets of thisdocument.
The ground terminal should be attached to the spindle housing as depicted inFigure 17.20. The stator is connected to the end shield via a screwedconnection.
The minimum diameter depends upon the motor type. All relevant informationis outlined in the section "Technical Data".
The minimum diameter also applies to the ground terminal, andmust be maintained!

14. Mounting Guidelines
Prior to attaching the motor winding cores in the junction box, check the sealsof the junction box:
• There must be a seal for both the junction box and the lid (see Figure 17.23).
• Both seals and seal surfaces must be in faultless condition.
Figure 14.23: Junction box seals
If the cables are attached in a junction box, then both the cable connectionsand the ground terminals must be equipped with terminal ends. The size of theterminal ends must correspond to the diameters of both the conductors andthe studs in the junction box.
The individual cores of the motor windings must be clearly labelledin the junction box. It is absolutely important that the conductors arenot confused!
Figure 17.25 illustrates an example of how to arrange the individual points ofconnection in a junction box.
Attach the individual conductors as follows:
• Screw the ring terminal of the ground terminal at its intended point.
• Using a washer, fasten the power terminal to the terminal stud (notetightening torque!). Connect them according to their designation:

14.8. Electrical check of the motor spindle
14.8.1 Running a high-voltage check
After mounting the stator and connecting the cores in the junction box or to theflange socket, it is necessary to run a high-voltage check.
This check is performed between windings, housing and NTC thermistors andis meant to test the insulating properties.
The proof voltage has to be a sinusoidal alternating voltage, Ueff = 1500 V.
The test must be performed as per DIN VDE 0530, section 1, para. 17.
Test recommendations:
The following readings must be taken and recorded (section 14.8.3):
• windings - housing
• windings - NTC thermistor 1
• windings - NTC thermistor 2
Procedure:
1. Those windings not to be tested must be connected to each other and to thehousing.
2. Apply voltage, Ueff = 1500 V, for five seconds to the relevant end of thewinding or parts to be tested.
3. Measure leakage current.
The test is successful if the leakage current is measured at ≤ 20 mA (with 1 MS375 ≤ 50 mA) with each reading.
The high-voltage check must be carried out by a qualified electricianor under the supervision of a qualified electrician!
Caution! If the leakage current exceeds the limit values indicated,it must be noted that the components are not sufficiently insulatedfrom each other!
During commissioning there exists:• danger to life and limb upon contact with the spindle housing and• the risk of damaging the machinery!
The frameless spindle motor must in not be started up! Find andremove any faults!
141• DOK-MOTOR*-1MB********-PRJ1-EN-E1,44 • 03.97
14. Mounting Guidelines
If the determined inductance values exceed the range permitted,then the characteristics curves of the drive can no longer berealized! There is, however, no danger that the electrical drivecomponents can be damaged during operation!
14.8.2 Running an inductance test
Once the entire motor spindle is mounted - including the installation of eitherthe junction box or the flange socket - the inductance values of the spindlemotor must be checked. These values are listed in section "Technical data" ofthe relevant 1 MB motor.
• Test conditions:
- Motor spindle temperature: approximately 20° C- Spindle is standing still
• Testing tools:
- Inductance measuring device with a measuring frequency of 1 kHz
• Test guidelines:
The reading will be taken between the three power terminals or powercontacts (see test protocol; section 14.8.3).
- reading of winding U - V
- reading of winding V - W
- reading of winding W - U
The values read may deviate ±10% from the inductance values listed in thetechnical data!
• Causes for deviating values:
- the diameter of the rotor after dressing is not correct, or,
- the rotor is defective.

The fit on the inside of the rotor may not be damaged during transportation.Any such damage will make it impossible to remove the rotor.
Use only sling hoisting belts made of plastic, or special hooks thatare sheathed in plastic, to lift or transport the rotor!

15.2 Stator
The stator must be stored dry, dust and vibration free. The permissibletemperature range is -25 °C to + 85 °C.
The stator may only be stored in a vertical/standing position!
The stator does not achieve its final rigidity until it has been mounted in thespindle housing. If it is stored in a horizontal/lying position, then the fit of thecooling jacket could be damaged!
Figure 15.2: Storing the stator
Lifting and transportingThe stator may only be lifted and transported in a vertical positionbefore it is screwed into the spindle housing! Appropriate chains orropes with suitable transport rings must be used!
This keeps the stator from bending and prevents damage to the fit on thecooling jacket which would make the stator unusable for mounting. Ringscrews per DIN 580 (see Figure 17.3) are suitable transport rings.

16. What is delivered
16. Condition at delivery
16.1 Delivery
Depending upon what is ordered, either an entire 1MB frameless spindlemotor is delivered or just individual parts (stator, rotor).
The items are delivered either on a palette or in a skeleton box. Rotor andstator are packed separately in styrofoam to prevent mechanical damage andknocking together during transport.
If several frameless spindle motors or components are simultaneously ordered,then these are packed together, if possible.
For protection against inclement weather, a carton is pulled over the paletteand affixed to it with taut-bands.
An envelope containing the delivery documents is attached to the carton.
There are also stickers on the packaging:
• one sticker with guidelines on the safe handling and transport of the order
• a barcode sticker (the number of stickers depends on order) with informationabout:
- the customer- the delivery slip number- consignment number- the carrier
(Also see section 17: "Identifying the merchandise".)

There is no additional documentation unless specifically requested.
The taut-bands must be cut open to unpack the order without causing damage.
16. What is delivered
There is tension in the taut-bands! The bands could lash out whencut open!
There is the danger of personal injury from the lashing out of the tautbands!
Sufficient distance must be maintained! Carefully release the tautbands!
The rotors of all types of frameless spindle motors will, in future, only bedelivered "dressed". This, in effect means, that Indramat will dress them totheir required exterior diameter (final dimensions).
This change is being instituted in a step-by-step fashion simply for organizationalreasons over an extended period one type after the other. Once a rotor typehas been converted to its final dressed delivery state, then it will no longer bepossible to obtain it undressed.
It will be possible to identify these "dressed" rotors at delivery by means of asticker.
In the event of any doubt, simply measure the outside diameter of the rotor andcompare the measured value with the dimensions on the relevant data sheet.
