Capacitor Start & Run (CSCR) Motors are combination of both PSC and CSIR motors. Every CSCR motor has a start-type capacitor in series with the auxiliary winding like the capacitor-start motor for high starting torque. And, like a PSC motor, it also has a run-type capacitor that is in series with the auxiliary winding after the start capacitor is switched out of the circuit. This allows high breakdown or overload torque.
Advantage of Amber CSCR motor is that it is such designed that it consumes lower full-load current and gives higher efficiency. CSCR motor is a real power house which are able to handle applications too demanding for any other kind of single-phase motor which include woodworking machinery, air compressors, high-pressure water pumps, vacuum pumps and other high torque applications.
