Abstract:
    A three-phase wound-rotor induction motor is prepared as setting triangle three-phase stator winding on stator and connecting wire outgoing end at top to wire outgoing end of three-phase power supply when motor is normally operated, series-connecting coils in each phase winding, switching on different power supply wire outgoing end and converting operation modes of start-up and normal operation by switch unit, arranging multiphase symmetric winding on rotor and forming composite coil by parallel-connecting two sub-coils with different number of turns in the same rotor groove.
