Capacitor Start/Capacitor Run AC Induction Motor
Capacitor Start/Capacitor Run AC Induction Motor motor has a start type capacitor in series with the auxiliary winding like the capacitor start motor for high starting torque. Like the permanent split capacitor (PSC) induction 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 overload torque.
This type of ac induction motor can be designed for lower full-load currents and higher efficiency. This ac induction motor is costly due to start and run capacitors and centrifugal switch.
And it is able to handle applications too demanding for any other kind of single-phase motor. These include woodworking machinery, air compressors, high-pressure water pumps, vacuum pumps, and other high torque applications requiring 1 to 10 horsepower (hp).
