How can the direction of a PSC motor be changed?

Changing the direction of a Permanent Split Capacitor (PSC) motor is primarily accomplished by modifying the connections of the stator windings. In the case of a PSC motor, this typically involves reversing the leads on either the start winding or the run winding. The winding configuration determines the magnetic field direction, and by reversing one of the connections, you effectively change the rotation direction of the magnetic field, which in turn changes the direction the motor spins.

This method is a practical and effective solution for altering motor direction without requiring extensive modifications or replacement of motor components. The other options offered do not effectively change the rotation direction or do not apply to PSC motors specifically.
