D-end and N-end

According to IEC 34-7, the ends of a motor are defined asfollows: D-end: the end that is normally the drive end of themotor. N-end: the end that is normally the non-drive endof the motor.

Direction of rotation

The cooling of the motors is independent of the directionof rotation, with the exception of some larger 2-polemotors.

If the mains supply is connected to the stator terminals,which are marked U, V and W, of a three phase motor andthe phase sequence of the mains is L1, L2, L3, the motorwill rotate clockwise, as viewed from the D-end. To reversethe direction of rotation, interchange any two of the threeconductors connected to the starter switch or motor.

Insulation and insulation classes

According to IEC 85, insulating materials are divided intoinsulation classes. Each class has a designation corres-ponding to the temperature that is the upper limit of therange of application of the insulating material under nor-mal operating conditions.

The winding insulation of a motor is determined on thebasis of the temperature rise in the motor and the ambienttemperature. The insulation is normally dimensioned forthe hottest point in the motor at its normal rated output andat ambient temperature of 40 oC. Motors subjected toambient temperatures above 40 oC will generally have tobe derated.

In most cases, the standard rated outputs of motors fromABB Motors are based on the temperature rise for insula-tion class B. Where the temperature rise is according toclass F, this is specified in the data tables.

However, all the motors are designed with class F insula-tion, which permits a higher temperature rise than class B.The motors, therefore, have a generous overload margin.If temperature rise to class F is allowed, the outputs givenin the tables can generally be increased by about 12 %.

Temperature limits are according to standards. The extrathermal margin when using class F insulation with class Btemperature rise makes the motors more reliable.

Symbols and units

Characteristics and tolerancesThe following tolerances apply to product catalogue tablevalues, as stated in IEC 34-1 ( in reference to guaranteedvalues).

Power factor

The power factor is determined by measuring the inputpower, voltage and current at the rated output. The tablevalues are subject to a standard tolerance of

– 1/6 (1-cos ϕ) Minimum 0.02 Maximum 0.07

Conversion factors for table data:

Speed, slip

The speed of motors applies at the rated output andoperating temperature. The standard tolerance on the slipis 20 % of the guaranteed slip. With regard to overspeed,the normal testing speed is 120 % of rated speed for 2minutes.

The slip is defined by the formula:

At part load the slip varies approximately in proportion tothe output.

Voltage and frequency

The table values for output, speed, efficiency, powerfactor, starting torque and starting current apply at therated voltage and frequency. These values will be affectedif the supply voltage or frequency deviate from the ratedvalues.

The motors can operate continuously at the rated output,with a long-term voltage deviation of 5 % from the speci-fied value or range of values, and at the rated frequency.The temperature rise may increase by 10 K. Voltagedeviations of up to 10 % are permissible for short periodsonly.

Torque

The maximum torque and the overload capacity, at ratedvoltage and rated frequency, is at least 160 % of the ratedtorque. The data tables state the maximum torque of eachmotor variant. If a higher maximum torque is required, alarger motor should be chosen.

If the mains voltage deviates from the rated voltage of themotor, the torque of the motor will vary, approximately inproportion to the square of the voltage. It is therefore vitalthat the cables supplying the motor are dimensionedgenerously, to ensure that there is no significant voltagedrop during starting or when the motor is running.

Torque T = Nm

T = torque, NmP = output power, kWn = motor speed, r/min

The standard tolerance of the table values for startingtorque is -15 to +25 %.The standard tolerance on the table values for maximumtorque is -10 %.

Efficiency

The efficiency at rated output, rated voltage and ratedfrequency is determined on the basis of bearing andfriction losses, iron losses, resistance losses and straylosses (summation of losses).

The table values are subject to standard tolerance inaccordance with IEC as follows, with the efficiency expres-sed per units:

- 15 % (1 - η) when P2 50 kW

- 10 % (1 - η) when P2 > 50 kw.

Electrical design

Starting of motors

Direct-On-Line starting (D.O.L.)The simplest way to start a squirrel cage motor is toconnect the mains supply to the motor, directly. In suchcases, the only starting equipment needed will be a direct-on-line (D.O.L.) starter. The starting current is high withthis method, so it has its limitations. This is, however, thepreferred method, if there are no special reasons foravoiding it.

Y/∆∆-startingIf it is necessary to restrict the starting current of a motordue to supply limitations, it is possible to employ star/deltastarting, e.g. a motor wound 380 V is started with thewinding Y connected. By this method the starting currentwill be reduced to about 30 % of the value for directstart and the starting torque will be reduced to about25 % of the D.O.L. value.

However, it must be determined whether the reducedmotor torque is sufficient to accelerate the load over thewhole speed range.

Starting timeThe starting current of an induction motor is always verymuch higher than the rated current, and an excessivelylong starting period causes a harmful temperature rise inthe motor. The high current also leads to electromechani-cal stresses. Catalogues usually state a longest startingtime that is a funtion of motor size and speed. There is nowa standardised requirement in IEC 34-12; instead ofstarting time, this specifies the permitted moment of inertiaof the driven machine. For small motors the thermal stressis greatest in the stator winding, whilst for large motors itis greatest in the rotor winding.

If the torque curves for the motor and the load are known,the starting time can be calculated by integrating theequation:

T – TL = (J

This method of calculation may be used for direct-on-linestarting and for motors up to about 250 kW. In other cases,more points on the motor torque curves are required, inany case up to the point of maximum torque.

If there is gearing between the motor and the drivenmachine, the load torque must be recalculated for themotor speed, by insertion in the following formula:

Torque on voltage deviation

Almost without exception, the starting current decreasesslightly more than proportionately to the voltage. Thus, at90% of rated voltage the motor will draw slightly less than90% of the starting current, say 87 to 89%. The startingtorque is proportional to the square of the current. The

Permitted starting time

In view of the temperature rise, the starting time mustnot exceed the time specified in the table.

The figures in the table are for starting from normaloperating temperature. They can be doubled if startingfrom cold.

Maximum starting times in seconds, for occasionalstarting

torque delivered at 90% of rated voltage is therefore only75 to 79% of the starting torque. Particular attentionshould be paid to these points if the electrical supply isweak and when starting techniques based on currentreduction are being used. The maximum torque is roughlyproportional to the square of the voltage.

Soft starters

The main circuit of the ABB soft starter is controlled bysemiconductors instead of mechanical contacts. Eachphase is provided with two antiparallel connected thyris-tors which allows current to be switched at any point withinboth positive and negative half cycles.

Thelead time is controlled by the firing angle of thethyristor which, in turn, is controlled by the built-in printedcircuit board.

The soft starter provides a smooth start at the same timeas the starting current is limited. The magnitude of thestarting current is directly dependent on the static torquerequirement during a start and on the load's mass whichis to be accelerated. In many cases, the soft starter savesenergy by automatically adapting the motor voltage con-tinually to the actual requirement. This is particularlynoticeable when the motor runs with a light load.

Motors of basic design are intended for operation in amaximum ambient temperature of 40oC and at a maximumaltitude of 1000 meters above sea level. If a motor is to beoperated in higher ambient temperatures or at higheraltitudes, it should normally be derated according to the

following table. Note that when the output power of astandard motor is derated, the relative values in catalo-gues, such as I

Duty types

The duty types are indicated by the symbols S1...S9according to IEC 34-1 and VDE 0530 Part 1. The outputsgiven in the tables are based on continuous running duty,S1, with rated output.

S1Continuous running duty

Operation at constant load of sufficient duration for thermalequilibrium to be reached.Designation: S1

In the absence of any indication of the rated duty type,continuous running duty is assumed when consideringmotor operation.

Inspection and testing

All motors supplied are inspected and tested.

IEC Publ. 34-1 and 34-2 describe various types of inspec-tion and testing of motors. The motors are inspectedduring testing, to ensure that they are free from defectsand that they have the desired characteristics.

Routine testingThis inspection is carried out on every motor. It involveschecking that the motor possesses the necessary electri-cal strength and that its electrical and mechanical perfor-mance is satisfactory.

Type inspectionType inspection is performed for one or more motors, todemonstrate that the characteristics and functions of thedesign are in accordance with the specifications of themanufacturer. Type inspection covers the inspection andtesting of:- electrical and mechanical operation- electrical and mechanical strength- temperature rise and efficiency- overload capacity- other special characteristics of the motor- type test reports can be issued to customers to provide typical performance values for purchased motors.

Random inspectionSubject to agreement at the time of ordering, the purcha-ser may select a certain number of motors from a specificorder, for more detailed inspection and testing, similar incontent to type inspection. The remaining motors undergoroutine testing.

Inspection for special motor versionsMotors to be used on board merchant vessels or inpotentially explosive areas must undergo additional in-spection and testing as laid down in the requirements ofthe relevant classification society or in applicable nationalor international standards.

Test reportsSubject to agreement at the time of ordering, the purcha-ser receives a copy of the inspection and testing report.

vibration, and noise of the motors. Different converterswith varying modulation and switching frequencies givedeviating performances for the same motor. The curvesshown in Figures 1, 2 and 3 can be used as a guideline forselecting the motor.

Frequency converter drives

When using a squirrel cage motor with a frequencyconverter the following points must be taken into account,in addition to the general selection criteria:

1. Always check– Motor and converter loadability for the actual application– Insulation level of the motor– Earthing and grounding arrangements of the motor,

driven machinery and possible tachometer.

2. At high speeds special attention should be paid to:– Bearing construction– Lubrication– Fan noise– Balancing– Critical speeds– Shaft seals– Maximum torque of the motor.

3. At low speeds the following should be noted:– Bearing lubrication– Motor cooling– Electromagnetic noise.

Guidelines for motor selection

The voltage (or current) fed by the converter is not pure-ly sinusoidal, which, as a result, may increase the losses,

Figure 1.

The guidelines present the maximum continuous loadtorque for a TEFC motor as function of frequency givingthe same temperature rise as rated sine voltage andfrequency with rated full load (normally B-class tempera-ture rise). Please note that the frequency converter app-lication in critical conditions may require a special rotordesign in frame sizes 355 and 400.

Insulation level

If the rated supply voltage is 500 V or less and you areusing an ACS 200 or ACS 500 or any other converter withIGBT-power components, no special check of the motorinsulation level is necessary. But if any other convertertype, with GTO- or GTR-power components supply, isused at 500 V or 575 V, check the cable length betweenthe converter and motor and use the insulation levelguideline (available on request) to obtain the correctmotor insulation. For voltages between 660 - 690 V werecommend a reinforced motor insulation because of thehigh voltage peaks.

Earthing arrangements

Correct earthing of the motor, driven equipment andtachometer is very important to avoid bearing currentsand bearing damages. We recommend that an earthinglead (as a matter of fact an equalising lead) is always usedbetween the motor frame and the driven machinery frame.This lead equalises the potential of both machines, thuspreventing any currents from going through the bearingsof both machines.

Note that with high switching frequency there is a highcapacitive connection between the motor winding and thestator core. No additional earthing current paths with thetachometer lead should be made.

High speed operation

In a frequency converter drive the actual speed of themotor may deviate considerably from its rated speed(rating plate speed). For higher speeds, ensure that thehighest permissible speed of the motor type – or thecritical speed of the entire equipment – is not exceeded.The permissible maximum speeds for standard motors(the basic motor) according to frame sizes are as follows:

63 - 100 6000 r/min112 - 200 4500 -"-225 - 280 3600 –"–315 2-pole 3600 –"–315 others 3000 –"–355, 400 2-pole 3600 –"–355, 400 others 2500 –"–

At high speeds bearing lubrication, ventilation noisesuppression and rubbing shaft seals will require specialattention. High speed grease, separate cooling fan andlabyrinth shaft seals may be necessary in difficult cases.Note that special high speed motors are available whichcan cover much higher speed ranges than above.

Low speed operation

At very low speeds the lack of cooling of a standard motorand the change in the distribution of the losses, affect themotor temperature balance increasing the temperature ofbearings. The effectiveness of the motor lubrication shouldbe checked by measuring the surface temperature ofbearing endshield during normal operating conditions. Ifthe measured value is +80°C or higher depending on thetype of grease, the relubrication intervals specified in ourmaintenance instructions must be shortened; i.e. therelubrication interval should be halved for every 15°Cincrease in bearing temperature. If this is not possible werecommend the use of lubricants for high operatingtemperature and with very low speeds the use of EP-grease alternatives.

Separate cooling

A separate cooling system may be necessary at lowspeeds (see dotted line in the guideline curves).

Noise

A separate cooling fan may also help in electromagneticnoise problems by ”damping” the pure tones which onecan hear in different modulation points. Theelectromagnetic noise is very much dependent on theconverter type (modulation, switching frequency etc) andon the construction and pole number of the motor.

Dimensioning the drive

1. General selection criteria:– Supply network voltage– Load torque type (constant, pump, decreasing)– Speed range– Special need for high starting torque– Special needs for environment etc.

2. Select a motor so that– The actual load torque is totally below the guideline

(Note you must know what kind of conventer you aregoing to use!) If the operation is not continuous in allspeed range duty points, the load torque curve mayexeed the guideline but this case requires specialdimensioning.

– The maximum torque of the motor is at least 40 % higherthan the load torque at any frequency.

– The maximum permissible speed of the motor is notexeeded.

Check if a separate cooling system reduces the motor sizeand consequently the converter size.

3. Select the right converter– according to the motor nominal power Pn. Check also

that the rated current of the converter is equal or greaterthan that of the selected motor. Check that the torqueratio of the motor is T

max/T

n 2.9. If not, you need

additional information for selection of the converter, ortake the next, higher rated converter

– Check that high starting torque requirements can berealized.

Computer disks containing information about the dimen-sioning of frequency converters are available from ABBIndustry.

Special attention has been paid to the finish of ABB'smotors. Screws, steel-, aluminium alloy as well as castiron parts are treated by a method appropriate to eachmaterial, thus giving reliable anti-corrosion protectionunder the most severe environmental conditions.The colour of the paint is blue, Munsel colour code: 8B 4,5/

3,25. It is also designated NCS 4822B05G.The standardpaint finish is moisture and tropic proof in accordance withDIN 50016. It is suitable for outdoor installations, includingchemical works. Specific details of paint types are given inthe respective product catalogues.

Drain holes

Totally-enclosed motors that will be operated in veryhumid or wet environments, and especially under intermit-tent duty, should be provided with drain holes. Theappropriate IM designation, such as IM 3031, is specified,on the basis of the method of motor mounting.

In the basic design, sizes 63 to 100 (in aluminium) and 71to 132 (in cast iron) are supplied without drain holes,although this can be provided as needed. If holes aredrilled, the degree of protection will change to IP 54. If themotors are provided with special felt plugs, the IP 55 willbe retained. Larger sizes are provided with closableplastic plugs in the drain holes. The plugs will be open, ondelivery. When mounting the motors, ensure that the drain

holes face downwards. In the case of vertical mounting,the upper plug must be hammered home completely. Invery dusty environments, both plugs should be hammeredhome.

Stator winding

Motor stators are wound with enamel wire and the windingis then impregnated with polyester or epoxy resin. The

winding satisfies insulation class F and is mechanicallystrong, moisture and tropic proof.

Rotor winding

The rotor cages are normally cast aluminium. In somelarger cast iron motor sizes, copper bars are used for

special applications, such as frequency converter drives.

Terminal box

The standard terminal box is located on top of the motor;the degree of protection is IP 55. Higher protection isavailable on request. In some types of motors, the terminalbox can also be on either of the sides.

The terminal box is either rotatable or at least allows cable

entry from either side which gives a choice of connectionpossibilities.

Standard terminal boxes are suitable for Cu-cables. ForAl-cable connection, please see the product catalogues.

Bearings

The motors are normally fitted with single-row deep grooveball bearings. The complete bearing designation is statedon the rating plate of most of the motor types.

If the bearing in the D-end of the motor is replaced with aroller bearing NU- or NJ-, higher radial forces can behandled. Roller bearings are especially suitable for beltdrive applications.

When there are high axial forces, angular-contact ballbearings should be used. This version is available onrequest. When a motor with angular-contact ball bearingsis ordered, the method of mounting and direction andmagnitude of the axial force must be specified.

For specific details about bearings, please see therespective product catalogues.

Transport locking

Motors that have roller bearings or angular-contact ballbearings are fitted with a transport lock before despatch toprevent damage to the bearings during transport. In case

of transport locked bearing, the motor is provided with awarning sign.

Locking may also be fitted in other cases where transportconditions are suspected of being injurious.

Lubrication

Smaller motors generally have bearings lubricated for life.Larger motor sizes usually have grease valves forlubrication in service.

The lubrication intervals and grease quantity are stated inthe maintenance instruction which comes with the motor.

For details of lubrication requirements, please see therespective product catalogues.

Bearing life

The normal life L10 of a bearing is defined, according toISO, as the number of operating hours achieved orexceeded by 90 % of identical bearings in a large test

series under certain specified conditions. 50 % of thebearings achieve at least five times this figure. Please seethe product catalogues.

Permissible bearing and shaft loadsThe maximum permissible radial or axial forces on theshaft end for which a definite bearing rating life is obtained

are shown in specific product catalogues. The strength ofthe shaft is also considered in the calculated values.

Balancing

The rotor is dynamically balanced with a full-sized key inthe shaft extension. For vibration, the standard motorssatisfy IEC 34-14 and ISO 2373 grade N. Grade R and Sto ISO 2373 are also available on request.

The vibration is expressed in mm/s, rms, and shall bemeasured under no load with the motor on elastic

mountings. The requirements apply over the measuringrange 10 to 1000 Hz.

On the delivery the motors will be marked with the methodof balancing.

H = half key, F = full key.

Noise levels

ABB's motors have a low noise level. Average test valuesare presented in respective product catalogues.

Guaranteed noise data can be supplied on request.

Addition of sound sources

Noise levels are expressed in decibels as logarithmicvalues which complicates the calculation of the cumulativeeffect of several sources. In order to add or subtractlogarithmic values, they must first be converted to absolutevalues. A simpler method of adding or subtracting soundsources is to use the diagram beside. When adding twosimilar sound sources, the total sound level will increaseby 3 dB, for 4 similar sources, by 6 dB, etc.

Sound is pressure waves and it is pressure that wemeasure. The pressure can then be converted intopower radiated from the sound source.

Sound pressure is measured on a logarithmic scale,referred to the lowest presure which can normally bedetected by the human ear.

p 2

Sound pressure level LP = 10 log dB p

0

where p0 = 2x10-5Pa.

Sound pressure and sound power

Information on sound pressure level is meaningful onlyif the distance from the sound source is stated. Forexample 80 dB (A) at a distance of one meter from apoint sound source corresponds sto 70 dB (A) at 3meters.

The sound pressure level is not an absolute measure ofthe acoustic properties of a sound source, since theacoustics of the room affect the propagation of thesound. It is therefore generally simpler to state thesound power level of a given source instead of thesound pressure level. However, since there is no way ofmeasuring the sound power level, it is calculated on thebasis of a sound pressure level measured under knownacoustical conditions.

Perception of differences in sound level

A difference in sound level of 1 dB is barely detectable,whereas a difference of 10 dB is perceived as a doubling,or halving, of the sound level.

When the difference between the two sound pressurelevels exceeds 10 dB, the lower level contributes so littleto the total sound pressure level that it may be disregarded.
