A 3-phase synchronous motor is running clockwise. If the direction of its field current is reversed
A)the motor will stop
B)the motor continue to run in the same direction
C)the winding of the motor will burn
D)the motor will run in the reverse direction

Question

Quizplus · Accepted Answer

Reversing the field current in a synchronous motor does not change the direction of rotation. The motor will continue to run in the same direction because its direction is determined by the sequence of the 3-phase power supply, not the polarity of the field current.
