capacitor-start induction motor

capacitor-start induction motor

An AC motor whose rotor is excited by voltage induced into it from the stator windings. A capacitor-start motor has two stator windings: a start winding and a run winding. The start winding is in series with a capacitor that shifts the phase of the current flowing through it, so it is out of phase with the current flowing through the run winding.

The magnetic field produced by the start winding and the field produced by the run winding work together to produce a magnetic field that rotates within the motor housing. The rotor follows this rotating field. When the rotor has accelerated to a specified speed, a centrifugal switch opens the start winding circuit, and the motor continues to operate on the run winding alone. Capacitor-start motors have a good starting torque.
