Which of the following motor has the poorest speed regulation ?
Correct answer: B. Series motor
- A. Shunt motor
- B. Series motor
- C. Differential compound motor
- D. Cumulative compound motor
Explanation
A series motor has poor speed regulation because its flux varies with load, producing a large change in speed between light-load and full-load operation. Shunt motors are the usual choice when nearly constant speed is required.
