In a capacitor start motor, the phase displacement between starting and running winding can be nearly
A. 10°
B. 30°
C. 60°
D. 90°
Answer:D
In a capacitor start motor, the phase displacement between starting and running winding can be nearly
A. 10° B. 30° C. 60° D. 90°
Explanation: To start single phase motors auxiliary winding or starting winding is used. The auxiliary winding is placed with a phase shift of 90° to the running winding and physically connected in parallel to the running winding.
