New Energy Sources WhatsAppSo, this motor has 2 windings, one for driving the actual motor and the other for either starting the motor or keeping the motor spinning. I don''t know which of these my 3-wire capacitor is doing. What I know is that the capacitor provides a phase change in the second winding so it can apply force when the motor is running.
New Energy Sources WhatsAppOnce the motor has started, the start capacitor needs to drop out of the circuit to prevent compressor/motor damage. This is done in 3 different ways. PRD (Potential Relay Device) - Most commonly found on aftermarket Supco hard-start kits, a PRD uses coltage or current sensing to drop the start capacitor from the circuit.
