![]() They will be the most reliable single-phase electric motor because no centrifugal beginning switch is required. Uses identical primary and auxiliary windings with a capacitor to supply starting torque. Application include small conveyors, large blowers, pumps, and direct-drives. It is a altered split-stage engine with a capacitor in series with the beginning winding to provide a start boost. The most typical single-phase motor used in industrial applications. ![]() Applications include small grinders, small supporters, and blowers. The “start” windings are positioned 90 degrees to the “run” windings and shift the magnetic field of the stator, inducing beginning torque. Split-Phase (induction start electric motor) Applications consist of fans and small appliances. This configuration causes a change of the used magnetic field in relationship to the rotor, creating stating torque. Shaded-pole: Have only one main winding no start winding. Torque-Speed Curves of Different Single-Phase Induction Motors They are the various Single Phase Induction Motor designations: Since no starting torque is obtainable, a design mechanism is included to start the motor. The single-phase motor operates beneath the same principle as the polyphase electric motor, except that the rotating magnetic field effect produced by the stator will not exist until running rpm is reached.
