MECHANICAL FEATURES

GENERAL

ENCLOSUREFrames 63 to 100 L with prefixes AD are ofdiecast aluminum. Foot mounted statorshave integral feet. TEFC & TE motors haveintegral longitudinal ribs for effective heattransfer. Specially designed roller tablemotors for steel plants have circular ribs toavoid deposition of dust & slags between theribs.

The stator & end shields are machined to

close tolerances for providing perfectalignment & fits.

Terminal boxes of frames up to 132M are ofdiecast aluminum alloy. Frame 160 & abovehave cast iron terminal box. All joints interminal box are sealed with gaskets.Motors above frame 160 have drain holes attheir lowest position as a standard features.

COREBoth stator and rotor cores are made ofhigh quality magnetic steel

WINDINGSStator and rotor (for SR motors) windingsconsists of modified polyester enamelcovered copper wire. Frame 280 and aboveare wound with dual coat copper wire as perIS: 13730-13. Motors wound with doubleglass covered conductors (as per IS: 1184)are also available on order for frame 160 andabove only.

INSULATIONAll motors are made with class F insulation asa standard feature.

The slot liners are either provided withdouble cuffing or edge binding at the slotmouth portion to strengthen the insulation.For frame 160 & above class F varnish orresin with vacuum pressure impregnation isused for impregnating the winding.

Epoxy gel cot is sprayed on all windingoverhangs (in frames 200 and above) toprovide mechanical rigidity to the winding

withstanding the electrical and mechanicalstresses

Surge testing is carried out on all windings inaddition to all other test ensuring healthinessof windings

The overhangs of SR rotors are banded with

resi-glass tapes under controlled tension, toprevent flaring under centrifugal force costby over speed.

ROTORThe rotor of SCR motors are made ofpressure diecast aluminum (or alloy in caseof special designs) up to frame ND355L.Rotors of specific polarity are made ofelectrolytic copper & copper alloy bars &rings connected by high quality silverbrazing.

The rotors of SR (slipring) motors are woundwith copper wire or strip. (See in winding andinsulation)

SLIPRING AND BRUSHGEAR SR motors are provided with slipring andbrush gear arrangement. The Slipring aremoulded in epoxy-based insulation and haveexcellent stability at high temperature andhave very good anti tracking property.Fabricated Slipring as per Steel Plant'sspecification (IPSS are also available onrequest for frames 160 & above.

3 Nos. brush holders with 2 nos each metalgraphite carbon brushes are provided- oneon each ring phase. The grade of carbonbrush is M15E of Assam carbon orequivalent. Each carbon brush is markedwith its grade and the line of wear, whichhelps in identifying replacement need.

The brush holders are made of brass. For160 to 200, self tension adjustment brushholders are used . Frames 225 and abovehave adjustable arms to suit the range of

slipring diameter. This always facilitatesangular adjustment of arms for radialplacement of brushes even after reduction indiameter of slipring resulting out of anyrework carried out in service for frames 225 &above. The brush tension is adjustable withthe help of adjustable nuts provided on thebrush arm. The sizes of brush andrecommended force for all frames are givenbelow:

ELECTRICAL FEATURES

Direction of RotationMotors are capable of rotating in eitherdirection except in 280/315 SPDP.Frame.2pole Motors. To reverse the direction ofrotation interchanges any of two-phaseconnection. For 2 pole motors in280/315SPDP frame the direction of rotationis to be specified at the time of ordering.Motors may be provided with arrow plate toindicate direction of rotation.

Starting Methods And Torque

DOL Starting: Direct connection to themains is the simplest method of starting forsquirrel cage motors. Normally, motorsUpto 2.2 Kw are started DOL, However allour motors are capable of starting on DOL.Star-Delta Starting The current impulsecaused during the DOL starting of motors ofhigher ratings, lead to the drop in the voltageof the system. In such cases the motors aregenerally started by means of star-deltastarters, wherein the motor terminals getconnected in star at the time of starting

thereby reducing the starting current. Whenthe motor is accelerated to nearly 70 % of fullspeed, the connections at the motorterminals are changed to delta, for the normalrunning of the motor on load SR Motors arestarted with SR starters having resistancebanks matching with rotor current of themotor. Star connected motor can have onlyDOL starting.

DUTY

The various operating cycles of drivenmachines can be classified into nine basicduties, ranging from S1 to S9 separatelyindicated in the following pages. Suitablemotors can be offered to match the dutycycles of the driven machines.

CLASSES OF DUTY

The following are the duty types:

S1 Continuous duty

S2 Short time duty

S3 Intermittent periodic dutyS4 Intermittent periodic duty with starting

S5 Intermittent periodic duty with startingand braking

S6 Continuous duty with Intermittentperiodic loading

S7 Continuous duty with starting andbraking

S8 Continuous duty with periodic speedcharges

S9 Duty with Non-periodic load & speedvariations.

Continuous Duty (Duty type S1)Operation at constant load of sufficientduration till thermal equilibrium is reached.

Short Time Duty (Duty type S2)Operation at constant load during a giventime, less than that required to reach thermalequilibrium, followed by a rest of sufficientduration to re-establish equality oftemperature with the cooling medium.

The recommended values for the short timeduty are 10,30,60 and 90 minutes.

Intermittent Periodic Duty (Duty type S3)

A sequence of identical duty cycles, eachconsisting of a period of operation atconstant load and a rest period, theseperiods being too short to attain thermalequilibrium during one duty cycle. In this dutytype, the starting current does notsignificantly affect the temperature-rise.Unless otherwise specified, the duration of

the duty cycle is 10 minutes. Therecommended values for the load factor are15,25,40 and 60 percent.

Intermittent Periodic Duty with Starting

(Duty type S4)A sequence of identical duty cycles, eachconsisting of a period of starting, a period ofoperation at constant load and a rest period,the operating and rest and de-energizedbeing too short to attain thermal equilibriumduring one duty cycle. In this duty thestopping of the motor is obtained either bynatural decelaration after disconnection ofthe electricity supply or by means of brakingsuch a mechanical brake which does notcause additional heating of the windings

Intermittent Periodic Duty with Startingand Braking (Duty type S5)

A sequence of identical duty cycles, eachconsisting of a period of starting, a period ofoperation at constant load, a period ofbraking and a rest period. The operating andde-energized periods being too short toobtain thermal equilibrium during one dutycycle

In this duty braking is rapid and is carried outelectrically.

Continuous Duty with IntermittentPeriodic Loading (Duty type S6)

A sequence of identical duty cycles, eachconsisting of a period of operation atconstant load and a period of operation atno-load, machines with excited windingshaving normal no load rated voltageexcitation. The operation and no-loadperiods are too short to attain thermalequilibrium during one duty cycle

Unless otherwise specified the duration ofthe duty cycle is 10 minutes.

The recommended values of cyclic durationfactor are 15,25,40and 60 percent.

Continuous Duty with Starting andBraking (Duty type S7)

A sequence of identical duty cycles eachconsisting of a period of starting, a period ofoperation at constant load and a period ofelectrical braking. There is no rest and de-

energized period.

19


25/87

Continuous Duty with Periodic Speed

Changes (Duty Type S8)A sequence of identical duty cycles eachconsists of a period of operation at constantload corresponding to a determined speedof rotation, followed immediately by aperiod of operation of another loadcorresponding to a different speed ofrotation (carried out, for example by meansof change of the number of poles in thecase of induction motors), the operatingperiods being too short to attain equilibriumduring one duty cycle. There is no rest and

de energized period.

Duty with Non periodic Load and speedVariation-( Duty Type S9)

A duty in which generally load and speedare varying non-periodically within thepermissible operating range. This dutyincludes frequently applied overloads thatmay greatly exceed the full loads, for thistype, suitable load values should be takenas the basis of the over load concept.

DESIGNATION

A duty type is designated by means of theabbreviation given below, For the duty typeS2 the abbreviation is followed by anindication of the duration of the duty , Forduty type S3 and S6 the abbreviation arefollowed by an indication of the cyclicduration factor .

Examples S2 60 minutesS3 25 percentS6 40 percent.

For the duty cycle S4 and S5 theabbreviation are followed by the indicationof the cyclic duration factor, the number ofthe duty cycles per hour (c/h) and the factorof inertia (FI)

Example: S4 25 percent 120 c/h FI 2Fro the duty type S7 the abbreviation isfollowed by the indication of the number ofcycles per hour and the factor of inertia

Example: S7 500 c/h FI 2

For the duty type S8 and S9 theabbreviation is followed by theindication of the number of the dutycycles per hour and the factor of inertiatogether with the load , in addition, thecyclic duration factor should beindicated for each speed.

Example:S8 or S9 30 c/h FI3 1.0 kW 740 rpm

40 percent

30 c/h FI3 4.0 kW 1460rpm 60 percent

30 c/h FI3 2.5 kW 980 rpm40 percent

LOCKED ROTOR CURRENT

(Starting Current)This is the current drawn by the motor atthe time of starting when started on DOL. Itis expressed as % age of the rated currentof the motor.The startng current varies proportionatelywith voltage from its rated value within thepermissible limits.

SPEED TORQUE CHARACTERISTICS

If the voltage varies from its rated within thepermissible limits, the starting, pull-up andpull-out torques vary as the square of thevoltage.

LOCKED ROTOR WITHSTAND AND TIME(THERMAL WITHSTAND TIME)

It is the time taken by the motor windings orrotor to reach the maximum limitingtemperature, during locked rotor condition,depending upon class of insulation, fromeither ambient temperature, or rated

service temperature.

Starting TimeIt is the time taken by a motor to come to its rated speed, when connected to load.Starting time depends upon:

2 2I. Total Inertia of the system i.e. GD of load referred to motor shaft speed plus motor GD .ii. Torque speed curve of the motor.iii. Torque speed curve of the loadStarting time should be lower than thermal withstand time for safe operation of the motor

Calculation of starting timeThe starting time can be calculated approximately by the following formulae

K x Total GD2t =a

Output x (K1-K2)Where ta = acceleration time (staring time) in secs.

K = 24.66 for 2 pole (3000 synchronous RPM)= 6.165 for 4 pole (1500 synchronous RPM)= 2.74 for 6 pole (1000 synchronous RPM)= 1.541 for 8 pole (750 synchronous RPM)

2 2 2 2Total GD = GD of motor + GD of load in kgmOutput = Output of motor in kw

Fan characteristics assumed, as load torque is proportional to square of speed.

The starting time can be more accurately determined by knowing the load torque speed curveand superimposing it on the motor torque speed curve.

Example

Consider a 2.2 KW 6 pole motor in frame 112 M for driving centrifugal fan.2 2 2 2Motor GD = 0.048 kgm load GD = 4.0 kgm

Breakaway Torque of the motor =2.0 full load torqueThe starting time would then be calculated as follows:

2K x Total GDta =

Output (KW) x (K1-K2)

2.74 X (0.048 + 4.0)=

2.2 X (2.0- 0.3)

= 2.895, say 2.9 seconds.

ACCESSORIES

When required, the accessories which areprovided with a motor, are thermisters, spaceheaters, sockets for customer's cable etc.compression glands; RTD and BTD for 280/315motors.

THERMISTERS

These are semi conductor devices, which have aproperty of suddenly changing their resistance ata definite temperature known as 'curie point'.Thermisters that may be provided on the motorsare those having 'Positive TemperatureCoefficient' (PTC); where the resistance suddenlyincreases at a 'Curie Point'. The thermistersgenerally provided are at 130c (PTC 130) forClass B temperature rise, 150C (PTC 150) Forclass F motors.

A combination of different ratings of thermisterscan be provided in same motor for 'Alarm & Trip'facilities for frame 160 and above only.

MODE OF ORERATIONThree thermisters connected in series are placedinside each of the phase windings of the motor.This gives protections against single phasing and

/or over heating due to excess load on the motor.

During normal operation the thermisters carry acurrent of few mA, which is sufficient to actuate arelay in control unit. This is in turn allows thecontactor operating coil to hold the starter in the'Run position. If the winding of the motor heats upto such an extent so as to bring the temperature ofthe thermisters up to 'Curie point'. The increase in

the resistance causes the relay to open and the

contactor to disconnect the motor supply, # Theleads of thermistors are terminated in the auxiliaryterminal box for frames 200 & above.

# For frame AD 63 to AD 100L and D80 thethermisters terminals are brought on the sameterminal block as that of main windings.SPACE HEATERSThese are provided over the windings of the motor.The main function of heaters, is to heat thewindings when motor is in idle condition or kept instorage , in order to prevent moisture or dewsettling over the windings and thereby reducingthe insulation resistance CAUTION-Supply to theheaters must be switched off before switching on

the motor. The motors are provided with spaceheaters for frames 90 and above only of ratings**40w, 50w, or 60w 240 V single phase dependingon the frame size. Like thermisters the spaceheater leads are also brought in the main terminalbox up to frame 180 and in a separate auxiliaryterminal box for frames 200 and above.

** 25 W, 240 V for frames 90/132.

GUIDE FOR MOTOR PROTECTION- FUSERATINGSIn addition to the starters (DOL or Star / Delta)being used to protect motors from overload andunder voltage, the motors are also to be providedwith back up fuse protections of suitable ratingsgenerally, depends upon the load characteristicsof the motors the fuse characteristics. The tablebelow gives general guidelines for selection of thefuse ratings.

TOTALLY ENCLOSED SQUIRREL CAGE INDUCTION MOTORS

AIR STREAM RATED MOTORS

These are totally enclosed motors without normal fan of TEFC motors. The applications of these motors are for fans,blowers, exhausts etc. Wherein the fan or impellers acting as load suck air from DE or NDE, that flows over the motor body.This air provides the cooling for the motors. Hence, it is necessary that the velocity of the air flowing over the motor shouldnot fall below the velocity of air due to normal fan of a TEFC motor. The minimum air velocity is given in the table below.

NON-VENTILTED MOTORSThese are totally enclosed motors, where the heat generated is dissipated by the body alone, with no provision for cooling.

As these motors are naturally cooled, the ratings are required to be offered in higher frames.

MULTI-SPEED MOTORSTable one indicates ratings of Multispeed motors for polarity ratio of 2/4p, 4/6p, 4/8p, 6/8p, and 6/12p. These are of tappedor PAM winding construction. For other ratios, please refer to us. Also three speed and four speed motors are offered asper customer's requirement.

The frame/output relationship in table one is confirmed subject to knowinga. Complete application details.b. Duty cycle/loading cyclec. Method of braking

2d. Load GD referred to motor speed.

Motors required for Multispeed/two speed operations are designed with two types of winding techniques

1. Tapped winding (also called Dahlander winding) where the two speeds are in ratio of 2:12. Separate windings one for each speed, when the output speeds are other than 2:1 ratio. The latter results in

considerable reduction in HP output.

Note: Motors will be suitable for DOL Starting only.

DUAL VOLTAGE MOTORSMotors can be offered for dual voltage operation. Such motors are so designed that they work satisfactorily onboth the voltages, but motor may not give optimum performance at both the voltage

Two kinds of dual voltage motors are offered.

Motors operating at voltages in a ratio of 1: 1.73 or 3Entire range of motors can be suitably wound to operate in such voltage combinations. This method is also known asDelta-Star reconnections. Motor is DELTA connected at lower voltage and STAR connected at higher voltage. 6 leadterminal blocks is fitted and suitable connecting links are provided (if required). These motors are suitable for standardsupply variations.

35


41/87

Example:

A motor designed for 380V operation (STAR connection) can also be run with 220V supply (MESH connection)380---- =1.73220

Hence merely by changing the position of connecting links, dual voltage operation can be achieved Alternatively this canalso be performed with the help of a suitable starter.

Motors operating on voltage in a ratio of 1: 2

This phenomenon involves Series Parallel connections in the windings. Motors are DELTA wound at both the voltages.Such motors have 9 leads (for DOL starting at both voltages) coming out from stator windings.

Slipring motors and Multispeed cannot be offered for dual voltage operations.

Flameproof motors are generally not offered with series parallel reconnection because of limitations of terminal studsinside the terminal box. However specific cases may be sent to Division for scrutinisation.
