___________________has least range of speed control?
Correct answer: B. Synchronous motor
- A. Slip ring induction motor
- B. Synchronous motor
- C. D.C. shunt motor
- D. Schrage motor
Explanation
A synchronous motor runs at synchronous speed, which is fixed by supply frequency and pole number, so its speed-control range is essentially zero under normal operation. The other motors permit some speed variation through their control methods.
