Once a PCS motor starts, what remains in the circuit?

When a Permanent Capacitor Start (PCS) motor begins its operation, both the capacitor and the windings are essential components that remain in the circuit.

The windings refer to the coils of wire that create a magnetic field, allowing the motor to function. Once the motor has started, the capacitor plays a crucial role in maintaining the efficiency and performance of the motor by providing additional phase shift necessary for effective operation.

In a PCS motor setup, after the initial start phase is completed, the capacitor remains connected to the circuit to ensure that the motor runs smoothly and with the required torque. This is different from other motor types, where the capacitor might be disconnected after starting. The combination of the windings and the capacitor allows for effective motor operation, whereas components like the start relay and switch may not necessarily remain in the circuit once the motor is running. Therefore, the presence of both the capacitor and windings in the circuit is pivotal for the ideal functioning of a PCS motor.
