While starting a synchronous motor by induction motor action, field winding is usually
A)connected to D.C. supply
B)short-circuited by low resistance
C)kept open-circuited
D)none of the above

Question

Quizplus · Accepted Answer

During the starting of a synchronous motor by induction motor action, the field winding is short-circuited by a low resistance. This is done to avoid high induced voltages in the field winding, which can be harmful.
