Single-Phase Induction Motors
The single-phase electric motor operates under the same principle as the polyphase motor, except that the rotating magnetic field effect generated by the stator will not exist until running rpm is sprockets reached. Since no beginning torque is available, a design mechanism is included to start the motor. They are the various designations:

Torque-Speed Curves of Different Single-Phase Induction Motors

Shaded-pole: Have only one main winding and no begin winding. This configuration causes a shift of the applied magnetic field in romantic relationship to the rotor, creating stating torque. Applications include enthusiasts and small appliances.

Split-Phase (induction start engine)
Has two models of stator windings. The “start” windings sit 90 degrees to the “run” windings and shift the magnetic field of the stator, inducing starting torque. Applications include small grinders, small supporters, and blowers.

Capacitor-Start
The most common single-phase motor used in industrial applications. It really is a altered split-stage engine with a capacitor in series with the beginning winding to provide a start boost. Application include small conveyors, huge blowers, pumps, and direct-drives.

Permanent-Split-Capacitor (PSC)
Uses identical main and auxiliary windings with a capacitor to supply starting torque. They will be the most reliable single-phase engine because no centrifugal beginning switch is necessary. Applications include fans and pumps in HVAC and refrigeration industries.
