Which of the following statements regarding two value capacitor motor is incorrect ?

The correct answer is D.

A two-value capacitor motor is a type of single-phase induction motor that uses two capacitors, one for starting and one for running. The starting capacitor provides a higher starting torque than a permanent-split single-value capacitor motor, which is why it is preferred in applications where frequent reversals are required. However, the starting capacitor also causes higher starting current, which can be a problem in some applications. The running capacitor provides a smoother running motor, but it does not provide any additional starting torque.

Here is a more detailed explanation of each option:

• Option A: This is correct. A two-value capacitor motor is a reversing motor, which means that it can be run in either forward or reverse direction. This is because the two capacitors are connected in different ways depending on the direction of rotation.
• Option B: This is correct. A two-value capacitor motor is preferred to permanent-split single-value capacitor motor where frequent reversals are required because it has higher starting torque. This is because the starting capacitor provides a higher starting current, which results in a higher starting torque.
• Option C: This is incorrect. A two-value capacitor motor has higher starting current than a permanent-split single-value capacitor motor. This is because the starting capacitor provides a higher starting current. However, the running current of a two-value capacitor motor is the same as that of a permanent-split single-value capacitor motor.
• Option D: This is correct. A two-value capacitor motor does not have high starting torque. This is because the starting capacitor provides a higher starting current, which results in a higher starting torque. However, the starting current is only required for a short period of time, and the running current of a two-value capacitor motor is the same as that of a permanent-split single-value capacitor motor.
