Which motor has the poorest speed control?
Correct answer: D. Series motor
- A. Differentially compounded motor
- B. Cumulatively compounded motor
- C. Shunt motor
- D. Series motor
Explanation
A series motor has very poor speed control because its flux changes substantially with load, causing large speed variations. Shunt and compound motors maintain speed more effectively.
