Multiple Choice

A permanent split-capacitor motor has a _______.

In a permanent split-capacitor motor, the phase shift needed to create torque comes from a run capacitor that stays connected to the auxiliary winding during operation. There is no separate start capacitor or centrifugal switch in this design, so the motor starts and continues to run with the same capacitor in place. This continuous, smaller phase shift provides running torque efficiently, without a distinct startup capacitor being disconnected later. That’s why the description is run capacitor only. The other options would imply a start capacitor, no capacitor at all, or both run and start caps, which doesn’t match how PSC motors are built.
