Single-Phase Induction Motors
The single-phase electric 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 system is included to begin the motor. These are the various designations:
Torque-Speed Curves of Different Single-Phase Induction Motors
Shaded-pole: Have only one main winding no begin winding. This configuration causes a shift of the used magnetic field in romantic relationship to the rotor, creating stating torque. Applications include supporters and small appliances.
Split-Phase (induction start engine)
Has two pieces of stator windings. The “start” windings are positioned 90 degrees to the “run” windings and change the magnetic field of the stator, inducing starting torque. Applications include small grinders, small followers, and blowers.
The most typical single-phase motor used in industrial applications. It really is a modified split-stage electric motor with a capacitor in series with the beginning winding to supply a start boost. Software 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 starting switch is necessary. Applications include supporters and pumps in HVAC and refrigeration industries.
