Bearingless switched reluctance linear motor

The invention provides a bearingless switched reluctance linear motor. The bearingless switched reluctance linear motor comprises a stator unit and a rotor unit, the rotor unit comprises a supportingshaft and a plurality of rotor salient poles coaxially and fixedly sleeving the supporting shaft, the rotor salient poles are arranged at equal intervals in the axial direction of the supporting shaft, and each rotor salient pole is of a polygonal prism structure; the stator unit comprises a plurality of stators which are arranged at equal intervals in the axial direction of the supporting shaft,and insulating check rings are arranged between the adjacent stators. The stator is provided with a plurality of salient poles, the salient poles are evenly arranged in the circumferential direction of the stator at equal intervals, the number of the salient poles is equal to and corresponds to the number of the surfaces of the polygon prism, the salient poles of the stator are provided with excitation windings, and the sa
