What is the function of capacitors on refrigeration motors?

Capacitors in refrigeration motors serve the critical function of storing electrical charges, which is essential during the starting and running phases of the motor. When a refrigeration motor starts, it requires a surge of electrical energy to overcome initial inertia. The capacitor provides this boost by releasing stored energy, enabling the motor to start effectively and reach operational speed.

Once the motor is running, the capacitor continues to play a role in improving the overall efficiency of the motor by supplying energy as needed during operation. This capacity for energy storage and release allows the motor to function smoothly and maintain consistent performance, preventing fluctuations that could lead to operational issues.

By assisting in the initial startup and supporting the motor during running, capacitors contribute significantly to the reliability and efficiency of refrigeration systems. This is why the function of capacitors is accurately described as storing electrical charges during the starting and running phases of the motor.
