The rotor of a synchronous motor contains a set of squirrel-cage bars similar to those found in an A-type rotor. This set of squirrel-cage bars is used to start the motor and is known as the ____ winding.
A) stator
B) phase
C) amortisseur
D) pseudo-squirrel-cage

Question

Quizplus · Accepted Answer

The set of squirrel-cage bars used to start a synchronous motor is known as the amortisseur winding. This type of winding helps the rotor achieve synchronism with the rotating magnetic field of the stator. Option A is incorrect because the stator winding is located in the stator, not the rotor. Option B and D are not correct terms used for the squirrel-cage winding found in the rotor.
