In a capacitor start and run motors the function of the running capacitor in series with the auxiliary winding is to
A. improve power factor
B. increase overload capacity
C. reduce fluctuations in torque
D. to improve torque
Answer:A
In a capacitor start and run motors the function of the running capacitor in series with the auxiliary winding is to
A. improve power factor B. increase overload capacity C. reduce fluctuations in torque D. to improve torque
Explanation: In capacitor-start, induction motor has good starting condition but poor running conditions because the capacitor is disconnected in running conditions.
