Single-Phase Induction Motors
The single-phase engine operates beneath the same principle as the polyphase motor, except that the rotating magnetic field effect produced by the stator will not exist until running rpm is reached. Since no beginning Single Phase Induction Motor china torque is available, a design system is included to begin the motor. They are the various designations:

Torque-Speed Curves of Different Single-Phase Induction Motors

Shaded-pole: Have only 1 main winding and no start winding. This configuration causes a shift of the applied magnetic field in relationship to the rotor, creating stating torque. Applications consist of fans and small appliances.

Split-Phase (induction start motor)
Has two pieces of stator windings. The “start” windings are positioned 90 degrees to the “run” windings and shift the magnetic field of the stator, inducing starting torque. Applications include small grinders, small followers, and blowers.

Capacitor-Start
The most common single-phase motor found in industrial applications. It is a altered split-stage motor with a capacitor in series with the start winding to supply a start boost. Software include small conveyors, large blowers, pumps, and direct-drives.

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