Which of the following statements regarding two value capacitor motor is incorrect ?
Correct answer: B. It is preferred to permanent-split single-value capacitor motor where frequent reversals are required
- A. It is a reversing motor
- B. It is preferred to permanent-split single-value capacitor motor where frequent reversals are required
- C. It has low starting as well as rushing currents
- D. It has high starting torque
Explanation
A two-value capacitor motor provides high starting torque with a large starting capacitor and efficient running with a smaller capacitor. It is not preferred for frequent reversals because its starting capacitor is switched out, making statement b incorrect.
