SHADING COIL TYPE SINGLE-PHASE INDUCTION MOTOR

摘要

PURPOSE: A shading coil type single-phase induction motor is provided to form the rotating field of sine waveform by installing rotatably a permanent magnet between a stator and an inductive rotor. CONSTITUTION: A shading coil type single-phase induction motor includes a housing(10), a shading coil type stator(20), a rotor(30), and a rotary shaft(40). The housing(10) includes a predetermined receiving region. The shading coil type stator(20) is fixed to an inner circumference of the housing. The rotor(30) is rotatably installed at a center of the stator. The rotary shaft(40) is fixed to a center of the rotor in order to transmit the torque to the outside. The shading coil type single-phase induction motor includes a cylindrical permanent magnet(50). The cylindrical permanent magnet(50) is located between the stator and the rotor. The cylindrical permanent magnet is independently rotated on an outer circumference of the rotor.
