Three-degree-of-freedom magnetic suspension switch reluctance motor

The invention relates to a three-degree-of-freedom magnetic suspension switch reluctance motor, and belongs to the field of magnetic suspension switch reluctance motors and magnetic suspension bearings. A motor stator is composed of a radial magnetic filed motor stator body and two magnetic bearing stator bodies. The radial magnetic filed motor stator body and the two magnetic bearing stator bodies are of a salient pole structure, a motor winding winds each stator tooth of the radial magnetic filed motor stator body, and a magnetic bearing winding winds each stator tooth of each magnetic bearing stator body. A rotor is composed of a salient pole rotor body and two cylindrical rotor bodies in an axial superposition mode, the salient pole rotor body is located between the two cylindrical rotor bodies and is used for generating torque, and the cylindrical rotor bodies are used for generating radial and axial suspension force. The three-degree-of-freedom magnetic suspension switch reluctance motor integrates a bearingless switch reluctance motor and an axial magnetic suspension bearing, and is high in integrity. Only one set of windings is arranged on the radial magnetic bearing stator teeth, the stator bodies are of the salient pole structure, and therefore a plurality of structure modes can be selected. The minimum inductance area is used for suspension control, suspension current has little influence on torque current, and the inter-phase coupling effect is little.
