For a motor-generator set which of the following motors will be preferred ?
Correct answer: A. Synchronous motor
- A. Synchronous motor
- B. Slip ring induction motor
- C. Pole changing induction motor
- D. Squirrel cage induction motor
Explanation
A synchronous motor is preferred for a motor-generator set because it maintains nearly constant speed and can operate at a desired power factor. This is especially useful when the generator must supply a constant-frequency output.
