In a PSC motor, which winding is energized during normal operation?

In a permanent split capacitor (PSC) motor, both windings are energized during normal operation. The run winding is connected directly to the supply, while the start winding is fed through a capacitor to create a phase shift between the two windings. This phase shift produces a rotating magnetic field that starts the rotor and then maintains torque as the motor runs. There’s no switch that disconnects the start winding in PSC motors, unlike some other motor types that drop the start winding after startup. So, during regular operation, both windings are energized.
