Which of the following single-phase motors has relatively poor starting torque ?
Correct answer: C. Capacitor motor
- A. Universal motor
- B. Repulsion motor
- C. Capacitor motor
- D. All single phase motors have zero starting torque
Explanation
A capacitor-run motor, often loosely called a capacitor motor, has relatively poor starting torque because its small running capacitor produces limited phase displacement at starting. Capacitor-start motors are specifically designed for high starting torque, but that option is not listed.
