Reactor Start Split Phase Induction Electric Motor Internal Wiring Diagram

Split Phase Capacitor Start Electric Motor

May be defined as a form of split-phase motor having a capacitor connected in series with the auxiliary winding. The auxiliary circuit is opened by the centrifugal switch when the motor reaches 70 to 80 percent of synchronous speed. Also known as a capacitor-start, induction-run motor. The rotor is a squirrel cage. The main winding is connected directly across the line, while the auxiliary or starting winding is connected through a capacitor which may be connected into the circuit through a transformer with suitably designed windings and capacitor of such values that the two winds will be approximately 90 degrees apart.
Motors of this type are suited for air conditioning and refrigeration applications, belt driven fans, etc.
