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.
