How is the capacitor wired in a PSC motor?

In a Permanent Split Capacitor (PSC) motor, the capacitor is wired in parallel with the motor windings. This configuration allows the capacitor to provide an auxiliary phase shift, enabling the motor to produce a rotating magnetic field. Because the capacitor is always connected in the circuit while the motor is running, it assists in starting and maintaining the required torque during operation. This design ensures that the motor operates efficiently and smoothly without the need for a starting capacitor that is disconnected after the motor reaches a certain speed.

The distinction of a PSC motor is specifically its reliance on the capacitor being in constant use for its operation. Hence, the correct understanding of how the capacitor is integrated provides insight into the motor's functionality and enhances troubleshooting and repair knowledge for technicians. This information is fundamental for oil heat technicians when working with such motors in heating systems.
