Motor Start Capacitor: Functions, Applications, and Failure Modes

Figure shows a circuit with a motor start capacitor and a motor run capacitor

A motor start capacitor is an essential component in single-phase electric motors. It provides the extra torque needed to start the motor under load. This capacitor creates a temporary phase shift in the electrical supply, generating a stronger rotating magnetic field to initiate motor operation. Start capacitors have a high capacitance value, typically ranging from …
