Single-Phase Induction Motors
The single-phase motor operates beneath the same principle as the polyphase engine, except that the rotating magnetic field effect generated by the stator does not exist until running rpm is reached. Since no beginning torque is offered, a design mechanism is included to begin the motor. They are the various designations:
Torque-Speed Curves of Different Single-Phase Induction Motors
Shaded-pole: Have only one main winding no start winding. This configuration causes a change of the applied magnetic field in romantic relationship to the rotor, creating stating torque. Applications include followers and small appliances.
Split-Phase (induction start motor)
Has two models of stator windings. The “start” windings are positioned 90 degrees to the “run” windings and change the magnetic field of the stator, inducing Single Phase Induction Motor china starting torque. Applications include little grinders, small enthusiasts, and blowers.
Capacitor-Start
The most typical single-phase motor found in industrial applications. It is a modified split-stage electric motor 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 primary and auxiliary windings with a capacitor to provide starting torque. They will be the most reliable single-phase electric motor because no centrifugal starting switch is necessary. Applications include followers and pumps in HVAC and refrigeration industries.
