Introduction

Axsys has designed, developed and pro-duced a very large variety of high accuracyresolvers and synchros for military and spe-cial industrial customers for more than 40years.These products are available eitherunhoused (frameless pancake type) orhoused (self-contained, with bearings).Special designs, from segmented multispeedunits to brushless designs with rotary trans-formers are supplied for a wide range ofdemanding applications.

The changing market is demanding lowercosts and shorter lead times; this hasprompted us to develop the most completeproduct line of standardized,V-Line™,resolvers in the market today.

The following pages provide both a designguide to help you specify your resolverrequirement and an entire library of highlytooled pancake designs ready for yourselection with extremely short deliveries.These are all proven designs, based on in-stock laminations, created to meet militaryspecifications, such as MIL-R-23417 andMIL-STD-202.

Transducer SelectionResolvers are superior to many other kindsof absolute position sensors because of theirruggedness, and ability to provide a veryhigh degree of angular accuracy undersevere conditions.There are no opticalpaths to keep clear of smoke or oils thatoften disrupt the operation of opticalencoders. Because they are a proportionaldevice, they are also less subject to inputsignal anomalies; a voltage or frequencyvariance will change both the sine andcosine outputs equally.

IntroductionV

LIneProducts

Resolvers are a cost-effective answer to yourcontrol needs.They save you size andweight, being substantially smaller than othertransducer approaches, and easily integratedinto your system, component or motordesign. Signal converters and balance circuit-ry can easily be incorporated into theresolver and/or output connector configura-tion.Ask our Sales Engineers about simplify-ing your design task with Axsys integratedpackages, including motion control compo-nents and related electronics.

V Line Products

Over the years Axsys Engineering has devel-oped many different pancake type resolversfor specific military and space programs, aswell as for motion controls in robotics andmachine tool applications.Axsys now offersa line of standard frameless pancakeresolvers, the V Line products, for the con-venience of our customers, and in order tominimize nonrecurring cost and deliverytimes.

lSleeves and hubs with flanges can be pro-vided as a special option. Flanges mayfurther increase structural stability forresolvers having thin cross sections orvery large diameters and ultimatelyincrease accuracy. They may also be usedas an alternative type of mounting. (seepage 19 for details.

lLead Break-out: Standard resolvers usually have flexible leads of 28 AWGTeflon® coated 7 strand color coded leadwires per MIL-W-16878/6, 18 incheslong. They provide a convenient meansfor the customer to connect the unit totheir system.

lResolvers can be provided with connec-tors as a special option. Units may alsoincorporate a “trim-board” to provideimproved accuracy with the use of exter-nal trim resistors. (see page 18 for

details). Terminals may also be providedfor special application. Consult Axsysfor lead specification on different unittypes.

AccuracyElectrical errors range from 15’ (arc min-utes) for low accuracy units to 5” (arc sec-onds) for high accuracy units. Availableaccuracies are listed in the data tables forevery unit type.

Resolver schematics and phase equationsare listed on page 78 at the end of the datapages for reference.

An explanation of the easy to use V Linenumbering system is given on page 25 at theend of this section. If you wish to specify aresolver exactly as it is specified in the tables,you need only to enter the part number. Ifyou wish to modify the part,AxsysEngineers will be happy to assist you indefining the modified part number to order.

Low Cost ApplicationsResolvers are more stable than potentiome-ters in varying environmental conditions,and are not sensitive to voltage or frequen-cy fluctuations. Resolvers can be placed onthe driven device or easily integrateddirectly into the motor, providing bothaccurate positioning information and feed-back to commutate a brushless motor.

High Precision ApplicationsResolvers can be made more compact thanoptical encoders and exhibit much highersignal-to-noise ratios than inductosyns.Combined with R-to-D converters, theirresolution and accuracy is as good or betterthan available optical discs.

There is an optimum speed for the highestaccuracy, depending on size and otherdesign parameters. Winding distributionand other factors act opposite to the aver-aging effect of the higher multispeeddesigns.

A resolver is an “absolute position transduc-er.” Comparison with “absolute encoders”favors the resolvers in price, size, installationconvenience, and stability.

Before You StartSelecting a rotary position transducer tomeet your application looks straightforwardat first.You know the accuracy and rotation-al speed you want and the rest involves sizeand installation.Then you start to thinkabout your system needs: temperature, shockand vibration, signal processing, effects ofload impedances, servo bandwidth and oper-ating environment. Is this resolver really forme?

Axsys' Engineers are prepared to help youthrough the selection process, assuring themost cost-effective product for your require-ment. If you are not familiar with specifyingresolvers we invite you to read through thefollowing tutorial before you tackle thespecification sheets.

How a Resolver Works

Stationary TransformersFundamental transformer theory is the basisof resolver design.An AC voltage is appliedto the primary winding (EIN) and a propor-tional output is developed on the secondary winding (EOUT).The proportional is basedon the ratio of turns on the secondary tothe primary, known as the transformationratio.

N2N1( )Transformer EOUT = EIN

Rotating Transformers (Resolvers)In a resolver the iron core for the primaryand secondary are two multitoothed lami-nation stacks, one being stationary (statorand one which rotates (rotor).The outputvoltage is affected by change in the positionof the secondary winding relative to theprimary winding.

As the rotor turns, the amplitude of thesecondary voltage changes, modulating theinput carrier. Secondary windings arealways placed with their axes at rightangles.This establishes two separate outputshaving a sine/cosine relationship.

Resolver FunctionsA resolver is an electromagnetic transducerthat can perform three basic functions: trans-mitting information, receiving informationand correcting information.The three typesof devices can be used as individualmachines or as a system with the unitsdirectly interfacing with each other.Theyare usually defined as follows:

“Resolver Transmitter” (RX):Converts mechanical position into an electrical signal.

“Resolver Receiver or Transformer” (RT):Translates electrical signals into angularposition in conjunction with a servo ampli-fier and electromechanical or hydraulicdrive.

“Resolver Differential” (RD): Provides a system correction by acting as a variable

electrical coupling between a RT and RX,adding a second angular vector to the inputsignal.

Resolver transmitters, receivers and differ-entials were widely used before the com-puter age to serve as computation devices,to resolve a vector representing voltage intoits orthogonal components, to convertcoordinates, rectangular to polar and viceversa, and to transmit angular positionswithout using complex electronics, such asconverters, or computers, which were non-existent, or large and very expensive at thetime. Some of these applications are still inuse today.

With an advance in electronics and com-puter technology, resolvers in modern sys-tems are more often used as highly accurateand reliable position sensors. In this capaci-ty they are connected to electronic circuits,including computers, directly or through“Resolver-to-Digital Converters” for digi-tal output.

Most applications require the conversion ofangular position into electrical signals.Thatis why most of the unit types in this catalogare Resolver Transmitters (RX). Axsys willprovide both resolvers receivers (RT) andalso Differential Resolvers (RD), if neces-sary, as a special option.

R to D ConvertersResolvers with an input AC reference volt-age (EIN) will have output voltages of:KEINsin u and KEINcos u.The Resolver-to-Digital (R-to-D) converter transforms thesesignals into easy to use digital representationof the angular position (u).When combinedwith such converters, resolvers can providedigital outputs with up to 22 bit resolutionsand system accuracies to 18 bit are achiev-able.

Resolvers are considered pancake types

There is a big advantage in using resolversas position sensor; accuracy is not affectedby TR, phase shift, voltage or frequencychanges.

when their diameter is greater than theirlength.They may be self-contained, havingtheir own bearings, brushes, etc. or they maybe frameless with separate rotor and statorparts designed to integrate directly into agimbal or other type of supporting structure.Frameless pancake resolvers offer manyadvantages to the designer of motion controlsystems.

Mounting frameless units direct to the sys-tem eliminates the error inherent with cou-plings and binding due to misalignment.

Direct placement of rotor onto the system shaft eliminates windup or backlash.

The large inside diameter of pancakeresolvers provides a convenient path forboth electrical and mechanical linkagessuch as wave guides, optics, electrical con-ductors and coolant lines. Units of this typecan be “wrapped around” the system forthe sake of simplicity, compactness andweight reduction.

Resolver WindingsA resolver functioning as a transmitter, hav-ing one primary winding requires at leasttwo secondary windings (sine & cosine)with axes in space “quadrature” (90 degreesapart). Primary and secondary windings canbe located on either a stator or rotor. In aresolver transmitter with one primarywinding it is usually located on a rotor, inorder to have only two leads on the rotat-ing part. One and two speed resolvers needto have a second “quadrature” primarywinding which is usually shorted internallyin order to equalize secondary short circuitimpedances, regardless of the positionalangle, improving accuracy. Low impedanceof the input voltage source essentially actsas a short on the main primary winding. Insome cases the leads of the quadraturewinding can be brought out to be used forangular correction.

Multispeed ResolversModern requirements for high resolutionand extremely accurate angular sensing anddata transmission have driven our develop-ment of a large variety of standard multi-speed resolvers.The number of pole pairs isreferred to as the resolver “speed,” so a 1speed (1X) has P = 1 pole pair (2 poles), an8 speed (8X) has P = 8 pole pairs (16

poles), etc.The ‘V Line’ of standard pancakeresolvers establish speed ranges of 2n pole

pairs (2, 4, 8, 16, 32), which are all readilyadaptable to digital systems.The increasednumber of pole pairs effectively increasessystem resolution by proportionately reduc-ing the number of rotational degrees repre-sented by one complete electrical cycle:

Multispeed resolvers can greatly enhancesystem performance, repeatability and relia-bility.The primary advantage relates to theaveraging effect of multipole designs; anylocal mechanical or winding perturbation is averaged in the distributed flux of the airgap.

Another advantages relates to effects fromcombined system errors which are dimin-ished by the number of pole pairs. Forexample:If the 1X Resolver Transmitter with 60”max error is used with R/D converter hav-ing 80” max error, then maximum systemerror will be:

60” (resolver) + 80” (converter) = 140”

If the 8X resolver with 15” max error isused with the same accuracy converter, thenthe resulting maximum error will be:

This is not the complete story of resolveraccuracy, however, as there is an optimumspeed for the highest accuracy depending onsize and other design factors.Winding distri-bution and other factors act opposite to theaveraging effect of the higher multispeeddesigns.

Mulitspeed windings alone can be used onlyfor the angular range less than 360º dividedby the number of pole pairs.To avoid ambi-guity when using a larger angular range,Axsys includes a 1 speed or 2 speed windingto provide the cyclical reference.These“coarse” windings are located on the samemagnetic core as the multispeed “fine”windings.Axsys employs proprietary tech-niques to minimize interaction of the differ-ent speed windings and assure accurate sig-nal interpolation on each channel.

Mulitspeed resolvers do not require a primary “quadrature” winding, since theirsecondary short circuit impedances are veryclose to the secondary open circuit

There is an optimum speed for the highestaccuracy, depending on size and otherdesign parameters. Winding distributionand other factors act opposite to the aver-aging effect of the higher multispeeddesigns.

impedences, and do not change significantlywith change of positional angle.Axsys Resolvers are designed to optimizestator/rotor slot combination in order toreduce common space harmonics andimprove angular accuracy. Every dimensionand tolerance is carefully chosen, and wind-ings are specially designed in order to makea near-perfect sinusoidal magnetic flux dis-tribution, and reduce the errors resultingfrom manufacturing limitations.

For super-high accuracy units, in order tocompensate for any remaining imperfectionsin the manufacturing process,Axsys hasdeveloped a special mechanical and electricaltrimming technique.

Specifying a Resolver

Once the basic function of the resolver hasbeen established it becomes important todefine the various inputs and outputs toinsure consistent performance across theoperating range. Our Application Engineerswill help you to avoid any surprises by asking about your particular installation.

The mounting and/or coupling of thedevice may be critical to the accuracy of aresolver.Axsys Engineers are ready to assistyou with each of these details, assuring youof the best solution for your application,however, it is still best to understand thesefactors and just how they can affect yourrequirements.The next few pages provideyou with all the knowledge you need toeffectively specify and select a resolver fromthe Data Pages that follow.

Resolver Parameters

Input Voltage and FrequencyPreferable voltage ranges for pancakeresolvers are from 1 to 26 volts and fre-quency ranges from 400 Hz to 5000 Hz.Developing special windings for every indi-vidual application is not always necessary,however, as a resolver can be operated atvoltages and frequencies other than thosespecified, when certain conditions are met.For this reason,Axsys has developed a fami-ly of resolvers designed to meet the morecommonly used 400 Hz and 2000 Hz exci-tation frequencies at a standard 26 volts. Inorder to take advantage of the standardized‘V Line’ designs, the designer should keepin mind the following points:

l Input voltage can usually be decreased for Resolver Transmitters (RX), withoutnoticeable change of other parameters.Since the transformation ratio stays the same, there will be some decrease in sensitivity, but it will not affect resolver performance. In some cases a reduction to .5 or 1.0 volt can be beneficial, for instance, when the resolver is energized through an R-to-D converter.

l Input voltage decreases to a Resolver Receiver (RT) may result in slightly increased error, since the resolver’s magnetic core will operate in the nonlinear portion of its magnetic curve.

lLarge voltage increases or frequency decreases can cause saturation of a resolver’s magnetic structure, resulting inincreased error and null voltage as well as changing some other parameters.







lHigher frequencies may result in increased magnetic flux leakage as well as changes in capacitance coupling.This, inturn, will degrade accuracy and increase null voltage.

Voltage SensitivityVoltage sensitivity is the output voltage perone degree of shaft angle.This parameter(also referred to as voltage gradient) is notusually specified, but can be easily calculat-ed.

Where:EIN is input voltage (RMS)K is the transformation ratio

a = 18 of shaft angleP = number of speeds

A 1 speed example:

Impedances, Current and PowerResolvers are like most other active ACcomponents, the ratio of resolver outputimpedance to that of the load must be keptlow to reduce effects on performance.Axsys has designed these components toprovide the lowest possible output imped-ance; for one speed units they are usually100 ohms or lower, for multispeed units,they seldom reach 1000 ohms.When usedwith R-to-D converters, which have inputimpedances larger than 250,000 ohms, theloading effect is negligible.

VS=EINK(17.45)

mVdegreeVS=EINKsin (Pa) 1000

Impedances are usually specified in rectan-gular form as R +jX where R is the “active component” and X is the “reactivecomponent.”Active component value is thesum of DC and AC resistive components;the DC resistive component depending onwire gauge and number of turns is tempera-ture sensitive, the AC component dependingon core losses resulting from the eddy cur-rents and hysteresis of the magnetic core isfrequency sensitive.

For the standard resolver magnetic coresAxsys uses high permeability nickel alloy.This material assures the best resolver char-acteristics and low core loss.

Axsys specifies the impedances based on thedefinition of primary and secondary wind-ings. If the primary windings are on a rotorside, then impedances are specified as fol-lows:

ZRO - Primary (rotor) open circuitZSS - Secondary (stator) short circuit

(For stator primary it will be ZSO and ZRS

respectively)

Primary Impedance (ZRO) defines the inputcurrent (IIN) and power (PIN) as follows:

Phase ShiftWhen a resolver is excited with an AC volt-age, the magnitude of its output voltage willbe proportional to the TR and will be atrigonometric function of the shaft position.In addition the output carrier AC voltagewill be “time delayed” from the input, sincea resolver is an inductive instrument.Thephase shift, expressed in degrees, is the dif-ference between the time phase of the pri-mary and secondary voltage, when theouput is at maximum coupling. Phase shift[[ can be approximated as follows:

Where:

RDC is the primary winding DC resistanceXL is the primary inductive component

Generally, one speed resolvers have a rela-tively small leading phase shift, between 0ºand 20º. Multispeed resolvers have a largerleading phase shift due to a larger R/X ratioand larger share of RDC in the resistiveimpedance component “R”. Its value isbetween 30º and 60º , and in some 16 or 32speed windings it may reach 65º to 70º(@400Hz). It decreases with the increase offrequency.

A large phase shift usually does not causeany problems in resolver performance. If theresolver is used with an R-to-D converter,then phase shift is recommended to besmaller than 45º by most converter manu-facturers. Phase shift can be reduced, if nec-essary, by using a resolver designed for high-er frequency, or by introducing a compensa-tion circuit.

RDC

XL[[ = arctan

Pancake resolvers in general have a relative-ly high ratio of R/X in their impedancevalues (in relation to regular size resolvers),since they have a smaller length. One speedpancake resolvers also have a relatively highshare of RAC in the resistive component(R), especially in high frequency units andin large diameter units.

In multispeed resolvers, ratio R/X is evenlarger than in one speed units but the shareof RAC in “R” component is much smaller.These features are mentioned here for bet-ter understanding of the changes in charac-teristics with temperature change.

Transformation RatioTransformation Ratio (TR) is the ratio ofoutput voltage to input voltage when out-put is at maximum coupling.TR is a con-stant for each design and is determined pri-marily by winding design, approximatelyproportional to the ratio of effective turns,secondary (N2) to primary (N1).

A higher TR presents no problems to onespeed resolvers. In multispeed resolvers,however, the increased R/X and increasedflux leakage makes it more difficult toachieve a higher TR. Compensating byincreasing the number of secondary turnsbecomes difficult with the high speedresolvers as very fine magnet wire must beused, complicating the manufacturingprocess.

Axsys specifies Transformation Ratios forone speed resolvers at 1.0 or at 0.454, andat 0.454 or at 0.200 for most of the multi-speed resolvers.

considered to be a “Null Voltage,” butbecomes one of the error components.

lQuadrature Fundamental component is 90º out of time phase with the in-phase component, and has the same frequency as the input voltage. It is called “Fundamental Null Voltage.”

lHarmonics add mostly third order time harmonics into a null voltage.The combined fundamental and har-monics create “Total Null Voltage.”

Null voltages in pancake resolvers are rela-tively low and do not cause any problems.They depend on size, input voltage, frequen-cy and resolver speed. Usually total null volt-age, of one speed resolvers, is approximately1 to 3 millivolts per volt of maximum out-put voltage; in multispeed resolvers it drops

Null Voltage“Null Voltage” is the residual voltage at thepoint of minimum magnetic couplingbetween the primary and secondary wind-ings. It is measured when the “in-phase”secondary voltage is zero.Theoretically, thisoccurs when the axis of the secondary andprimary windings are orthogonal, the pointof minimum coupling. Mechanical imper-fections, winding errors, and both electricaland magnetic short circuits can cause somevoltage to be induced, however, eventhough the principal magnetic axis are per-pendicular to each other.

The “Total Null Voltage” has three compo-nents: in phase fundamental, quadraturefundamental, and harmonics.

to 0.2 to 0.5 millivolts per volt of maxi-mum output volt. Null voltage is specifiedin resolver drawings as a “max” value.

In all Axsys Pancake Resolvers total nullvoltage is very close to fundamental nullvoltage. Operating at 400 Hz and 2000 Hz,the ‘V Line’ Resolvers are designed for lowflux density eliminating concerns over satu-ration that adversely effect 60 HZ and non-pancake type devices.

Accuracy

Zero AlignmentFor dual speed resolvers when both coarse(single speed) and fine (multispeed) wind-ings are located on the same laminationstack there are interactions that must beconsidered in design and installation ofyour resolver.There can exist a differencebetween the mechanical angle of theElectrical Zeros (EZ) of the coarse and finewindings.This specification must be takeninto consideration by the system designer.

Electrical ErrorElectrical error in the representation of theexact mechanical position of the rotor withrespect to the stator is the most importantresolver parameter. For Resolver Trans-mitters accuracy is the error in conversionof rotor position into electrical signals. ForResolver Receivers accuracy is the error inconversion of electrical signals into rotorposition. It is defined as the differencebetween the position of the rotor calculatedfrom electrical signals and the actual rotorposition in mechanical degrees.

1P( ) Esin,i

Ecos,i

Where:P is the resolver speed

ai is the actual rotor position, in mechanical degrees

Esin,i is a secondary “sine” voltage for position “i”

Ecos,i is a secondary “cosine” voltage for position “i”

Accuracy is specified as a maximum value oferror over the entire operating angular rangeof the resolver. It is specified in “arc min-utes” or “arc seconds” in the Data Pages.

Axsys design and manufacturing proceduresminimize the possibility of irregularities inwinding distribution and other assembly fac-tors that contribute to inaccuracies. For veryhigh accuracy resolvers Axsys developed aspecial trimming technique, to trim certainerror components down either mechanicallyor by use of external trim resistors. Examplesof actual error curves are shown on page 14.Maximum errors can be very low (5 to 10seconds of arc). Compensating certain errorcurve harmonics using electronics canreduce them even further.

Axsys manufactures exceptionally reliable,multispeed and segmented positioningsensors which can be absolute positionsensors providing a high degree of angularaccuracy and extremely high resolution.







Velocity ErrorA resolver has many of the electromagneticcharacteristics of a motor when operatingat high speeds and electrical errors canoccur as the rotational speed approaches thesynchronous velocity. Fortunately mostpancake resolvers are operated in the nearstatic conditions at very slow speeds, and“velocity errors” are nonexistent. In specialapplications like high speed motor controls,these errors should be considered.As arule-of-thumb, speeds above one-forth ofthe synchronous speed should be avoided.An easy way to calculate synchronous speedis as follows:

Synchronous Rotational Velocity (RPM)

For example, a 16 speed resolver at400 Hz has synchronous velocity of:

Therefore, rotational speed should be heldbelow

Loading EffectsLoading presents almost no problem formost installations of Axsys Resolvers becausethey are designed for the lowest possibleoutput impedance.The rule-of-thumb isthat the electrical loading should be at leastten times greater than the output short cir-cuit impedance, and the standardized multi-speed units are seldom above 1000 ohms.Single speed units are usually less than 100ohms. If the output load impedance happensto be very small however, output voltagewill decrease, input current and null voltagewill increase, and the accuracy will degrade.

When used with R-to-D converters, whoseinput impedances exceed 250,000 ohms, theloading effect is negligible.

If loads of 10,000 to 20,000 ohms or less areused, the most important thing to watch isthe load imbalance. If the ratio of load resist-ance to output resolver impedance (RL /ZSS)is low, the load imbalance can cause addi-tional resolver error.

Accuracy

Resolvers are available with transmitter,differential or receiver functions.Specifically design to withstand high-impact (shock) and environments contain-ing dirt, grease, oil or other contaminants.Available housed or unhoused, in a varietyof configurations.







Hi-Pot tests are performed per militaryspecifications at 250 volts RMS and 60 Hz;leakage current is to be less than 1 milliamp.Insulation resistance tests are run at 100 voltsDC; resistance is to remain above 50megohms.

Axsys uses the highest quality insulationmaterials and impregnation varnishes, closelycontrolling manufacturing processes andincoming inspection of vendor materials.Insulation quality is guaranteed, even underthe most hostile environments. Special mate-rials may be specified for operation in highradiation environments as well as for hightemperature (up to 200ºC) and space or vac-uum applications requiring low outgassing.

Temperature EffectTheoretically, the electrical error of a givenunit should not change with the change oftemperature, since errors are a result ofdesign limitations and manufacturing inac-curacies. However, mounting and tempera-ture stresses may cause error variations.Usually, these variations do not cause changein the shape of the error curve, but changethe position of the electrical zero. It isreferred to as “EZ Shift.”

Axsys Pancake Resolvers are always designedand manufactured to minimize any possiblestress that could result in EZ shift. If sleeveand hub are used, their coefficient of ther-mal expansion matches the one of the lami-nation material. However, EZ shift alsodepends on customer mounting, and cus-tomer choice of materials. If mounting recommendations are followed, then EZshift is minimal.

One speed resolvers are more sensitive to temperature variations than multi-

For one speed resolvers, an approximaterelation between (RL /ZSS ) and additionalerror is as follows:

0.5% load imbalance will result in about 50” error

0.1% load imbalance will result in about10” error

0.5% load imbalance will result in about20” error 0.1% load imbalance will result in about 4”error

For multispeed resolvers the error valuesshould be divided by the number of speeds,again making the multispeed unit a moreattractive selection.

InsulationBoth dielectric withstanding voltage andinsulation resistance tests check the qualityof insulation between different windings,and between windings and the magneticcore.Dielectric withstanding voltage test (whichis also called a High Potential or “Hi-Pot”test) also proves a resolver’s ability to with-stand momentary voltage surges whileoperating at its normal specified levels ofusually 26 volts. Insulation resistance testscheck for any breakdown in the insulationof the windings when an over-voltage con-dition is applied.

speed resolvers. For properly mounted pancake resolvers, approximate level of EZshift versus temperature can be as follows:

l For one speed units, approximately 1 to 2 arc seconds/°C (dependent on size and rigidity)

l For multispeed units (8X or 16X),approximately 0.1 to 0.3 arc seconds/°C

Changes in phase shift and TransformationRatio (TR) versus temperature are a pri-mary result of resistance changes in the copper magnet wire of the resolver primarywinding. Increased temperatures result inhigher resistance, increasing the phase shiftand decreasing the TR. One speed units inthis case are much less sensitive to tempera-ture variations than multispeed units, sincethe share of DC resistance in the total primary impedance value in multispeedresolvers is much greater than in one speedresolvers.

Fortunately these changes do not result inaccuracy degradation.This is a big advan-tage in using resolvers as angular positionsensors; the accuracy of angular conversiondoes not depend on TR, phase shift, pri-mary voltage or frequency changes.Thesechanges affect the output voltages on sineand cosine secondary windings the sameway, and their ratio, which determines theconverted output remains constant.

There are some applications, where second-ary resolver voltage is used as a reference,and must remain constant with a high

degree of accuracy over the operating tem-perature range. Phase shift must remain at0º. In this case,Axsys can provide a specialresolver with compensated windings,trimmed through a compensation amplifieras an option (see Compensated Resolvers) atright.

Special Options

Connectors and Trim BoardsAxsys will provide connectors, if necessary.They can be attached to every unit type ifthe customer specifies this feature. In orderto keep rotor and stator leads separate, onecan use two connectors. If the customerwants,Axsys can tie rotor and stator leadstogether, and attach only one connector.A trim board can also be attached if theresolver requires electrical trimming toincrease accuracy.

Mounting Recommendations

Resolvers are easy to install.They are morerigid and reliable than optical encoders orinductosyns.They also withstand moresevere environmental conditions.Frameless pancake resolvers are suppliedwith rotor and stator, to be separatelyinstalled in the enclosure, axially alignedand concentric to each other and the axisof rotation.They only need, typically. to beput at electrical zero by slight adjustment ofstator angular position, relative to the rotor.One speed resolvers are affected by eccen-tricity or by mechanical and temperaturestress much more than multispeed resolvers.Improper mounting of a one speed resolvercan cause change of the electrical errorwithin several angular minutes.The numberof pole pairs in a multispeed unit dividesthis same error. However, multispeedresolvers are usually specified more accuratethan one speeds units, and the effect can bejust as critical.

When resolvers (one speed or multispeed)are used over a small angular range theyexperience less influence from impropermounting conditions than those with fullrotation.

Pancake resolvers constitute a relatively thinset of rings designed to take up as littleroom as possible and to reduce weight.Sleeves and hubs add rigidity for highaccuracy applications.Axsys provides pre-cisely ground mounting surfaces for statorOD and rotor ID as well as square shoul-ders which allow the customer to mountthe unit concentrically in the system. Insome very large diameter resolvers, howev-er,Axsys recommends some differentmounting techniques. See following page.

Installation

Here are some helpful hints when developing procedures for resolver installations.

l Do not apply excessive force when mounting the resolver components.Thismay cause distortion that will affect its electrical performance.When inserting the stator or rotor into the system enclosure try to push it straight, apply-ing even pressure around the surface of the unit.When properly installed, it should be able to be turned, but there should not be any radial movement possible.

l Concentricity requirements are specifiedon the outline drawings for each unit.Usually a rotor and stator should be mounted concentric to the axis of rota-tion starting from .0003 to .0005 inch for high accuracy, relatively small units to .001 to .002 inch for the more rigid or larger units having bigger air gaps.The rule-of-thumb is that concentricity will not affect performance if it is with-in 10% of the rotor/stator air gap clear-ance dimension.

l Axial alignment tolerance on V Line Pancake Resolvers should be maintainedat ±.005 inches.

l The stator and rotor positions depend not only on the concentricity of mounting surfaces, but also on the gap between mounting and resolver surfaces.This fit should not be too loose, causing concentricity errors, nor too tight, causing distortion of the resolver. It can be from .0002 to

.0003 inch for small units to 0.001 inch for large units.

l In order to minimize the effects of temperature change, the coefficient of thermal expansion should match that of the resolver as closely as possible.Axsys’ Standard Pancake Resolvers have coefficient of expansion equal to 10x10-6 per degree C.

l Do not use excessive force in clamping the resolver in place. Bare resolvers, without sleeves or hubs are especially sensitiveto distortion. If you are cementing the unit in place, be sure to use a material that remains somewhat flexible under dif-ferent temperature conditions; in order tominimize temperature-related stress.

l For the very large units Axsys incorpo-rates some special features, which ease their mounting. In the size 083 Axsys provides axial holes through the stator and rotor lamination stacks (12 or 16 in.each).The unit is mounted concentric,using accurate OD and ID cylindrical surfaces and is attached to the enclosure by screws, going through the axial holes.This feature eliminates the need to have special clamps that would increase the diameter of the mounting enclosure.
