Function & Operation

A run capacitor works by gathering and storing electrical energy, then releasing it as needed to maintain an optimal phase shift between current and voltage in the motor’s auxiliary windings. This ensures consistent torque, improved efficiency, and smoother operation. Unlike start capacitors that are only active during startup, run capacitors remain energised throughout the motor’s operation. They have lower capacitance values, longer lifespans, and are engineered for continuous-duty use with minimal failure rates.
