Damper windings in a synchronous motor are provided on:
- Pole faces
- Rotor shaft
- Stator frame
- None of the above
Correct answer: 1. Pole faces
Explanation: One of the methods to start a synchronous motor is to employ amortisseur or damper windings. Amortisseur windings are special bars that are laid into notches that are carved in the face of a synchronous motor’s rotor and then shorted out on each end by a large shorting ring.
