1. General information

2. Description

1. General information

The applicable national, local and plant-specific regulations and requirements must be observed.

Technical details may vary for special designs and constructions. In case of doubt it is urgently recommended that the manufacturer is contacted, giving details of the type and serial number (No. …. see rating plate), or have the maintenance work carried out by a service centre.

2.1 Field of Application

Intended use of the motors: The motors are constructed in protection class IP55 (protection class: see rating plate). They may be installed in dusty or damp environments. For use outdoors an additional covering is recommended to avoid the tong-term influence of direct intense sunlight, rain, snow, ice or dust. If necessary, consultation/technical coordination is advisable. Ambient temperature: ......... -20°C to +40°C

Installation altitude: ............. ≤ 1000 m In case of differing ambient conditions, these must be indicated on the rating plate. The details on the rating plate then apply.

2.2 Cooling

1MA motors are self-cooling (with fan).

3. Information on the correct handling of electric motors

3.1 Transport and storage

When transporting the motor, all available lifting lugs must be used. When transporting sets of machinery (e.g. gearbox, fan, pumps etc.) only use the attached lifting lugs. Sets of machinery must not be lifted by hanging on the motor lifting lugs. With long periods of storage the period of use of the bearing grease is reduced. For storage of longer than 12 months the condition of the grease must be checked. If the check reveals contamination of the grease (ingress of condensation causes a change in consistency of the grease) the grease must be replaced. The roller bearings should be replaced if the time from delivery to commissioning of the motor exceeds 4 years. The probable life-span of the bearing system reduces with increasing storage time. Machined surfaces (flange surfaces, shaft ends, etc.) should be protected with corrosion protection agents. If necessary, the insulating resistance of the windings must be checked, see Section 3.6.

All work must be carried out only when the system is in an electrically voltage-free state.


3. Notes

3.2 Installation

For vertical configuration, all available lifting lugs and if necessary lifting straps (DIN EN 1492-1:2000) and/or tie-down straps (DIN EN 12195-2:2001) must be used to stabilise the position. Attachments must not be used as lifting aids. After installation, screwed-on lifting lugs must be tightened or removed. For vertical installation with the shaft end pointing downwards, a protective cover for the fan cover is recommended, to prevent the entry of foreign bodies. On the other hand, in the case of shaft ends pointing upwards, the ingress of liquids along the shaft must be prevented. Smooth running: Precise alignment of the clutch and a well-balanced drive element (clutch, pulleys, fan …) are prerequisites for smooth vibration-free running. Complete balancing of the motor and the drive elements may be necessary.

3.3 Terminal box

Tightening torques for the screws of the terminal box: See Fig. 4.2.

3.4 Balancing, drive elements

The fitting and removal of drive elements (clutch, pulley, gear wheel,…) must be performed with suitable equipment (see Fig.7). As standard, the rotor is balanced with half parallel key. When fitting the drive element, pay attention to the type of balancing! The balancing condition is stated on the end face of the shaft or the type plate (H = half, F = full parallel key balancing, N = balancing without parallel key). The drive elements must be balanced according to ISO 1940:2003.

For balancing with half parallel key, the protruding visible portion of the parallel key Tp must be machined off (see Fig. 8).

The generally necessary measures for protection against touching the drive elements must be observed.

3.5 Electrical connection

All work must only be carried out by qualified technicians on stationary low-voltage machines which have been switched off and secured against switching on again. This also applies to the auxiliary power circuits. The terminal box must be sealed against dust and water. The mains voltage and frequency must conform to the data on the rating plate. A voltage deviation of ± 5% and/or a frequency deviation of ± 2% are permissible. The connection and configuration of the jumpers must be performed according to the circuit diagram in the terminal box. Connect the bonding conductor to this terminal

. For connection terminals with terminal bridges (e.g. according to DIN 46282) the conductors must be arranged so that approximately the same terminal heights result on both sides of the bar. This type of connection therefore requires that individual conductors are bent to a U-shape or a fork terminal must be connected (see Fig. 5) This also applies to the bonding connector and the external green/yellow earthing conductor.


3. Notes For tightening torques of screw connections of the electrical connections and terminal board connections (except for the terminal bar) see Fig. 4.

3.6 Checking the insulation resistance

Prior to the initial commissioning of the motor after a long period of storage or standstill (approx. 6 months) the insulation resistance of the windings must be checked. During and immediately after the measurements, the terminals have voltages which can be dangerous, and must not be touched. Insulation resistance The minimum insulation resistance of new, cleaned or repaired windings against earth

is 10 MΩ. Initially, the critical insulation resistance Rkrit is calculated. The calculation is made by

multiplying the measured voltage UN, e.g. 0.69 kV AC, with the constant factor (0.5 MΩ /kV): Rkrit = 0.69 kV x 0.5 MΩ /kV =0.345 MΩ Measurement: The minimum insulation resistance of the winding against earth is measured with 500 V DC. The temperature of the windings should be 25°C ± 15°C. The critical insulation resistance must be measured with the windings at operating temperature using 500 V DC. Testing: If for new or cleaned windings or repaired motors, which have been stored or not used for long periods, the minimum insulation resistance of the winding against earth is less than 10 MΩ, this may be caused by moisture. The windings must then be dried. After long periods of operation the minimum insulation resistance may fall to the critical insulation resistance. As long as the measured value does not fall below the calculated value for the critical insulation resistance, operation of the motor may continue. If this value is fallen below, the motor must be switched off immediately. The cause of this must be established and if necessary the windings or parts of the windings must be repaired, cleaned or dried.

3.7 Commissioning

NOTE: Electromagnetic compatibility Production of interference: Great differences of torque (e.g. when driving a piston compressor) induce a non-sine wave motor current, whose harmonics can cause an impermissible effect on the mains and therefore impermissible production of interference. With supply by frequency inverters, various strengths of interference are produced according to the design of the frequency inverter (type, interference suppression, manufacturer). The EMC information of the inverter manufacturer must be observed. If a shielded motor supply cable is recommended, the shielding is most effective if a large area is electrically connected to the metal terminal box of the motor (with metal screw connectors). With motors with integrated sensors (e.g. thermistors) interference voltages due to the inverter may be produced in the sensor cables. Interference immunity: For motors with integrated sensors (e.g. thermistors) the operator must ensure adequate immunity to interference by the selection of a suitable sensor cable (possibly with screening, with connection as for the motor supply cable) and evaluation device. When operating motors with inverters at higher speeds than the nominal speed, the mechanical limiting speed (Safe operating speed IEC 60034-1) must be observed (max. 3000 1/min).


4. Maintenance

Safety measures Before starting any work on the motor or the device, but especially before opening the covers of active components, the motor must be isolated according to regulations. In addition to the main power circuits, any additional or auxiliary circuits must be taken into account.

The usual "5 Safety Rules" e.g. according to EN 50110-1 (DIN VDE 0105) are:

• Isolate, • Secure against switching on, • Check for no voltage, • Earth and short circuit, • Cover or fence off neighbouring live components.

These measures may only be removed when the maintenance work is complete and the motor has been completely assembled. NOTE: If the motors are designed with closed condensation outlets, these must be opened occasionally in order to allow any accumulated condensation to drain off. Condensation outlets must always be located at the lowest point of the motor. Changing bearings, grease packing Bearing replacement period [h] under normal operating conditions, with horizontal installation of the motor, cooling medium temperature or motor speed:

40°C

up to 1800 min-1 approx. 40000 h

up to 3000 min-1 approx. 20000 h

NOTE: The permissible axial and transverse forces must not be exceeded. Independent of the hours of operation of a motor which is in use, the roller bearing should be replaced approximately every 3 years due to the reduction of lubrication. Under special operating conditions, e.g. vertical motor installation, heavy loads due to vibration and shock, or operation with frequent reversing, the operating hours stated above are significantly reduced. The motors have groove ball bearings with cover plates (2ZC3 design). The material of the plates should be temperature resistant from -30°C to +150°C, e.g. polyacrylic rubber (ACM). Grease types for standard machines: UNIREX N3 (ESSO); Substitute greases must comply with DIN 51825-K3N:2004. Special greases are indicated on the rating plate or on an additional plate. Dismantle the motor to the necessary extent. Remove the roller bearing using suitable equipment (see Fig. 6). Clean any contamination from the bearing seats. Uniformly heat the roller bearings to approx. 80-100°C and fit. Hard blows (e.g. with a hammer) must be avoided. Any warn sealing elements (e.g. shaft seals) must also be renewed. If shaft sealing rings without springs are installed, the replacement component must also be installed without springs. Centring edge seal When assembling the motor, the bright fitting surfaces between the motor housing and the bearing covers must be sealed with a suitable non-hardening sealing compound, e.g. Fluid-D. Tightening torques for the screws on the bearing covers: see Fig. 4.2. Regreasing device For motors with regreasing devices, the details on the lubrication plate or the rating plate must be observed. Regreasing should be performed with the motor running.


4. Maintenance General overhaul A general overhaul of the motor must be carried out every 5 years. For this the motor must be dismantled. The following work must be carried out:

• All components of the motor must be cleaned • All components of the motor must be examined for damage • All damaged components must be replaced • All roller bearings must be replaced • All seals and shaft sealing rings must be replaced • Measure the insulation resistance • Check the stationary voltage according to EN 60034-1

The general overhaul must be carried out by qualified personnel in a specialist workshop with appropriate equipment. We strongly recommend that the general overhaul is carried out by NORD-Service.


5. Motors with increased ignition protection, type "e" Ex e

5. Motors with increased ignition protection, type "e" Ex e 1MA

Identification: CE 0102 II G Ex e lI T3 Attention Repairs must be carried out in or by authorised workshops. Repairs must be documented on the motor (e.g. additional plate).

The increased hazard in areas endangered by explosions or fire damp requires particularly careful observation of the general safety and start-up information. Replacement parts - Only original replacement parts (see replacement parts list) may be used: this particularly applies to seals and connection components. Exceptions are standard equivalent commercially available components (e.g. roller bearings).

Explosion-protected electrical machines comply with standards: EN 60034-1:2004 and all relevant parts, as well as EN 60079-0:2004, EN60079-7:2003. They may only be used in explosion hazard areas according to the conditions stipulated by the responsible supervisory authorities. They are responsible for the determination of the explosion hazard (allocation of zones). If the certification is supplemented with an "X" the special conditions in the EU prototype certification must be observed. The cable entries must be approved for explosion hazard areas and secured against spontaneous loosening. Unused openings must be closed with approved stoppers. For the assembly of the cable entries the instructions in the instruction manual of the cable entry manufacturer must be observed. The number of threaded holes, the thread sizes and the type of thread are given in Table 1. Special entries are indicated. For vertical installation of the motor with the end of the shaft facing upwards or downwards, e.g. types IMV3, IMV6, IMV19, for 1MA motors a cover must be arranged so that foreign bodies cannot enter into the motor fan cover. Cooling of the motor must not be obstructed by the cover. If nothing is stated to the contrary in the EU prototype certification or on the rating plate with regard to type of operation and tolerances, electrical machines are designed for continuous operation and normal infrequent starts, in which there is not significant start-up warming. The motors may only be used for the type of operation stated on the rating plate. Range A in EN 60034-1:2004 - voltage ± 5%, frequency ± 2%, curve shape, symmetrical mains - must be complied with in order that warming remains within the permissible limits. Larger deviations from the rated values can cause a permissible warming of the electrical machine and must be stated on the rating plate. The temperature class of the motor stated on the rating plate must conform with the temperature class of any escaping inflammable gases. In addition, the safety device must be adjusted to the rated current. A triggering device certified according to RL94/9/EU must be used. Thermal protection of the machine by means of direct temperature monitoring of the windings is permissible, if this is certified and stated on the rating plate. An earthing tab is cast onto the housing for the connection of the external bonding cable. The thread sizes for the screws of this external bonding cable are stated in Table 2.



In the case of external sources of heat or cold, no additional measures are necessary if the temperatures of the attached components do not exceed the permissible temperatures listed in Table 3. The values in Table 3 apply for an ambient temperature of -20°C to +40°C with self-ventilation. Special applications with external sources of heat and cold must be examined by means of type testing with regard to the effect on the maximum surface and operating temperatures and suitable measures taken if necessary. For the installation of electrical equipment in explosion hazard areas in Germany, attention is drawn to DIN EN 60079-14:2003 and the "Betriebssicherheitverordnung" [Operating Safety Regulations]! In foreign countries the appropriate national regulations must be observed. Operation with an inverter must be explicitly certified. The separate manufacturer's information must be observed.

5.1 Additional information for operation with a frequency inverter

In addition to this information, the operating instructions of the frequency inverter and if necessary the operating instructions of the gear unit and any other operating instructions must be observed. Failure to observe these can cause material damage and personal injury. Series 1 MA7 motors are produced in the ignition protection type "Increased Safety" and are suitable for operation with a frequency inverter. The suitability can be identified by the statement of the maximum frequency (e.g. f max 100 Hz) on the type plate. Individual acceptance by a designated testing facility is not necessary. It is essential that the supplied data sheet for the EU prototype certification (see Section 7.) is complied with. This includes important information for operation and commissioning. Ex e motors suitable for use with frequency inverters are equipped with a triple PTC. This must be evaluated by a certified triggering device with protection type labelling Ex II (2) G. The joint operation of several motors on one frequency inverter is not permissible. Connecting cables must be dimensioned for a continuous thermal load of at least 80°C. In addition, the frequency inverter used must be equipped with a speed-dependent current limitation (Precision of measurement of effective current: 5%). The current limitation is set to the maximum permissible nominal current of the frequency inverter. A limitation of the output current of the frequency inverter to double the rated current of the motor must be ensured. Observation of the rev/f characteristic and the permissible torque depending on the frequency is essential. Voltage drops due to the use of long supply cables and/or sine wave filters between the motor and the frequency inverter must be taken into account. The maximum permissible length of cable is 30m. The frequency inverter also causes a drop in voltage. The motor terminal voltage can be influenced by increasing the input voltage of the frequency inverter. Voltages in excess of 1556 V (peak values) must not occur at the motor terminals. Unfavourable cable lengths and short switching times of the frequency inverter can cause impermissible overvoltages. The occurrence of such overvoltages must be ruled out before starting up.

This must be taken into account for the design of the motor, the parameterisation of the inverter (e.g. rev/f adaptation) and for the minimum input voltage of the inverter.

The maximum input voltage of the inverter is 500V.

Adaptation of the rated voltage of the motor by means of the number of windings is permissible. The rated current changes in inverse proportion to the rated voltage.

Sheet 1/3


7. Data Sheets



Monitoring devices To prevent impermissible heating due to overload, the motors are monitored by connection to a device for direct temperature monitoring in combination with defined setting data of the inverter. Due to the special characteristics of motors supplied by inverters and the adapted monitoring device, details of the relationship IA/IN and the heating time tE are not required for motors operated by inverters.

The type of device for direct temperature monitoring has been tested by the Physikalish-Technische Bundesanstalt and consists of three DIN 44082 type M 110 PTCs installed in the windings and a function-tested triggering device according to Guideline 94/9/EU.

With a line current of 1.7 A and a blocked shaft, the PTC must trigger after 31.4 s (± 20 %) assuming a cold condition (20 °C).

By means of the temperature monitoring device, temperature class T3 as per EN 60079-7 is complied with.

Inverter setting data

In combination with the aforementioned monitoring device, the following inverter data must be set and maintained during operation:

Minimum pulse frequency: 3 kHz

Short-term current limit: 1.5*IN

Maximum overload time: 60 s

Minimum frequency fmin: 10 Hz

Maximum frequency fmax: 100 Y / 100 Δ Hz

Permissible duration of operation at fmin:

60 s

The maximum overload time and the permissible duration of operation at fmin refer to a time period of 10 min.

The relationship of the torque to the frequency results from the permissible continuous current limit.

The current monitoring of the frequency inverter must record the effective value of the machine current with a tolerance of ± 5 % in relation to the rated current of the motor. Before start-up it must be ensured that no overvoltages due to the inverter with a peak value in excess of

1556 V (2* 2 *550V) occur at the terminals of the electrical machine.

The voltage depends on the input voltage of the frequency inverter, the voltage drop at the filter and over the motor supply cable and may not fall below the design value by more than 5% according to IEC 60034 - 1 Range "A", even with minimum input voltage of the frequency inverter. This must be taken into account for the design of the motor, the parameterisation of the inverter (e.g. rev/f adaptation) and for the minimum input voltage of the inverter.


Adaptation of the design voltage of the motor by means of the number of windings is permissible. The rated current changes in inverse proportion to the rated voltage.
