How does a run capacitor function?

A run capacitor’s primary role is to gather and store energy from its source, then release it as needed by the circuit. It introduces a phase difference between the current and voltage in the auxiliary start windings of a motor. By doing so, run capacitors consistently supply the system with the necessary power for optimal performance. Consequently, they remain energised while the system operates. A distinguishing feature of run capacitors, in comparison to start capacitors, is their notably lower failure rate and reduced capacitance value. They are engineered for continuous use.
