Single-Phase Induction Motors
The single-phase motor operates beneath 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 reached. Since no Single Phase Induction Motor china starting torque is obtainable, 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 1 main winding and no begin winding. This configuration causes a change of the applied magnetic field in romantic relationship to the rotor, creating stating torque. Applications include enthusiasts and small appliances.
Split-Phase (induction start electric motor)
Has two units of stator windings. The “start” windings are positioned 90 degrees to the “run” windings and shift the magnetic field of the stator, inducing beginning torque. Applications include small grinders, small fans, and blowers.
The most typical single-phase motor used in industrial applications. It really is a altered split-stage electric motor with a capacitor in series with the beginning winding to provide a start boost. Program include small conveyors, huge blowers, pumps, and direct-drives.
Uses identical primary 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 required. Applications include followers and pumps in HVAC and refrigeration industries.
