In a capacitor start motor, the phase displacement between starting and running winding can be nearly__________?
Correct answer: D. 90°
- A. 10°
- B. 30°
- C. 60°
- D. 90°
Explanation
A capacitor-start motor is designed to produce a large phase difference between the starting and running winding currents, approaching 90°. This large displacement gives it much higher starting torque than an ordinary split-phase motor.
