Motor Start Capacitors

Our Motor Start Capacitors are engineered to deliver the high starting torque required for single-phase electric motors. Designed with superior dielectric materials and robust construction, these capacitors ensure quick motor start-up, improved efficiency, and long service life across demanding industrial and commercial applications.

As a trusted motor start capacitor manufacturer, we supply capacitors that meet international quality and performance standards, making them suitable for OEMs, panel builders, and maintenance professionals.

What Is a Motor Start Capacitor?

A motor start capacitor is a short-duty capacitor used to provide an extra power boost during motor start-up. It creates a phase shift in the auxiliary winding, enabling the motor to overcome initial inertia and reach operating speed smoothly. Once the motor starts, the capacitor is disconnected from the circuit.
