Mostly, synchronous motors are of_____________?
Correct answer: C. salient pole type machines
- A. alternator type machines
- B. induction type machines
- C. salient pole type machines
- D. smooth cylindrical type machinesIndustrial Materials & Equipment
Explanation
Most synchronous motors operate at relatively low or medium speeds, where salient-pole rotors are economical and provide the required magnetic flux. Smooth cylindrical rotors are mainly used for high-speed turbo-alternators.
