A motor has the following information on a plate stamped onit:
500 hp, 4160 VAC, 3-phase, 1700 RPM, 60 hz, 0.75 PF,Code G, Insulation Class F
c. According to NEMA, Code G motors are expected to have lockedrotor rating in the range 5.6 – 6.29 kVA/HP. What is the lockedrotor current at maximum locked rotor kVA/HP? [Answer: 436.5 A. The“locked rotor” means that under the condition that electric poweris supplied to the field coil the rotor stops turning, such as whenthe load on the motor is too large for the motor to keep turning.The motor starts to overheat at that condition, so a circuitbreaker with at least the maximum current rating must be includedin the circuit. The “locked rotor” condition is not the startingcondition for the motor.]
