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

Question

Quizplus · Accepted Answer

The set of squirrel-cage bars in the rotor of a synchronous motor is used to start the motor and is known as the amortisseur or damper winding. This winding helps the motor to start smoothly and also provides damping to prevent oscillations during transient conditions. The other options, asynchronous, field resistor, and electromagnetic, do not accurately describe the purpose or function of the squirrel-cage bars in the rotor.
