Hybrid stator type permanent magnet biased magnetic suspension switch magnetic resistance motor

The invention relates to a hybrid stator type permanent magnet biased magnetic suspension switch magnetic resistance motor comprising a salient pole type external stator, a salient pole type rotor, three salient pole type internal stators and two permanent magnet rings. The external stator, the rotor and the three internal stators are nested from outside to inside in such a way that the same central axis is shared by the same; the three internal stators are horizontally distributed along an axial direction, the permanent magnet rings are placed between the three internal stators, and the permanent magnet rings are nested in such a way that the permanent magnet rings and the internal stators share the same central axis. The permanent magnet rings are magnetized axially, a bias magnetic field is provided, and suspension force is generated after the bias magnetic field is superposed on a control magnetic field generated via suspension windings on two internal stators. A magnetic flux pathof a main winding on the external stator and a suspension magnetic flux path are mutually independent; a coupling problem between a starting function and a rotor suspension function can be solved, the bias magnetic field is provided by the permanent magnet rings, operation loss of the motor is reduced, and reliability of motor operation can be improved.
