Motor Run Capacitor

Available in: Dry Type in PP & Aluminum Can in both Pin & Wire type

MOTOR RUN CAPACITOR Single-phase AC electric motors require a “Run Capacitor” to energize the second-phase winding (auxiliary coil) to create a rotating magnetic field while the motor is running. Motor run capacitors are designed for continuous duty while the motor is powered. Run capacitors are mostly polypropylene film capacitors and are energized the entire time the motor is running. Motor run capacitors are also usable for general sine wave applications such as filters, inverters, UPS devices, etc.

Faqs

What is the difference between a Motor Run Capacitor and a Motor Start Capacitor?

A Motor Run Capacitor provides continuous power to the motor during operation, while a Motor Start Capacitor is used only during the motor's start-up phase.

How do I choose the right Motor Run Capacitor for my equipment?

Always select a capacitor with the voltage and capacitance ratings specified by the motor manufacturer to ensure compatibility.

What happens if a Motor Run Capacitor fails?

A failing capacitor can lead to reduced motor efficiency, overheating, or complete motor failure.

Are Halcap Motor Run Capacitors suitable for HVAC systems?

Yes, they are widely used in HVAC systems, refrigerators, and other equipment requiring consistent motor performance.
