Diagram shows polar¡ty of interpoles with respect to the polarity of
the main poles.
For a MOTOR, the polarity of the interpole is the same as that of the
main pole PRECEDING it in the direction of rotation.
For a GENERATOR, the polarity of the interpole ¡s the same as that
of the main pole FOLLOWING it in the direction of rotation.
3.4 1.7 1.5TThese are average direct-current quantities. Branch-circuit
conductors supplying a single motor shall have an ampacitynot less than 125 percent of the motor full-load currentrating.
Armature Current Varies lnversely as Applied Voltage.Example: 40 HP Motor, 300 Volt Armature
ARMATURE CURRENT: 140 x ffi: r12 AMPS

EFFECTS OF VOLTAGE UNBALANCE ONMOTOR PERFORMANCE
COMPARISON OF METHODSOF STARTING SQUIRREL CAGEINDUCTION MOTORS
Should voltages be unbalanced, the rated horsepower of the motorshould be multiplied by the factor shown in the graph below to reducethe possibility of damage to the motor. Operation of the motor abovea 5 percent voltage unbalance condition is not recommended.Alternating-current, polyphase motors shall operate successfullyunder runn¡ng conditions at rated load when the voltage unbalanceat the motor terminals does not exceed 1 percent. pelormance willnot necessarily be the same as when the motor ¡s operating with abalanced voltage at the motor terminals.
PERCENT VOLTAGE UNBALANCE
MEDIUM MOTOR DERATING FACTOR DUE TOUNBALANCED VOLTAGEPercenl Voltage Maxìmum Voltaoe Deviation from Averaoe VonaqeUnbalance - rw^
Example-With voltages of 460, 467, and 450, the average is 459, themaximum deviation from the average is 9, and the

POWER FACTOR IMPROVEMENTOF INDUCTION MOTOR LOADS
When power factor correction capacitors are used, the total correc-tive KVAR on the load side of the motor controller should notexceed the value required to raise the no-load power factor to unity.Corrective KVAR in excess of this value may cause over exc¡tationthat results in high transient voltages, currents and torques that canincrease safety hazards to personnel and possibly damage themotor or driven equipment.
Do not connect power factor correction capacitors at motor term¡-nals on elevator motors, multispeed motors, plugging or joggingapplications or open transition, wye-delta, auto-transformer start-ing and some part-winding start motors.
lf possible, capacitors should be located at position No. 2 (seediagram). This does not change the current flowing through moloroverload protectors. Connection of capac¡tors at position No. 3requires a change of overload protectors. Capacitors should belocated at position No. 1 for applications listed in Paragraph 2above. Be sure bus powerfactor is not increased above 95 percentunder all loading conditions to avoid over excitation.

DETERMINING THE POLARIZATION INDEXOF MOTOR AND GENERATOR WINDINGS
Knowing the polarization index of a motor or generator can beuseful in appraising the fitness of the machine for service. Theindex is calculated from measurements of the winding insulationresistance.
Before measuring the insulation resistance, remove all externalconnections to the machine and completely discharge the windingsto the grounded machine frame.
The polarization index is calculated as the ratio of the 1O-minute tothe 1-minute value of the insulation resistance, measured consec-utively:
POI.ARIZATION INDEX : Resistance after 10 minutesResistance after 1 minute
The recommended minimum value of polarization index for a-c andd-c motors and generators is 2.0. Machines having windings with alower index are less likely to be suited for operation.The polarization index is useful in evaluating windings for:
-Build up of dirt or moisture.
-Gradual deterioration of the insulation (by comparing results oftests made earlier on the same machine).
-Fitness for overpotential tests.
-Suitability for operation.The procedure for determining the polarization index is covered indetail by IEEE Standard No. 43.

The insulation systems are arranged in order of their insulationlevel and classified by a letter symbol or by a numerical value.The numerical value rerates to the temperature crassification ofthe insulation system.
The temperature classification indicates the max¡mum (hot-spot)temperature at which the insulation system can be operated foinormal expected service life.
ln general, all materials used in a given insulation system shouldbe rated for temperatures equal tó, or exceeding, lne tempera-ture classification of the system.
