Motor capacitors temporarily store an electrical charge to provide extra torque and improve a motor's performance and efficiency. Start capacitors deliver extra torque during motor startup, then exit the circuit once the motor reaches operating speed. Run capacitors help the motor maintain a consistent charge while running. Power factor correction capacitors reduce motor power consumption caused by heavy inductive loads by balancing working power and supplied power. Motor capacitors are primarily used for powering motors in HVAC applications such as fans, blowers, and compressors, but they are also used in a variety of equipment including pumps, conveyors, and machine tools.
