摘要
The present invention relates to an axial phase-split permanent bearingless switched reluctance flywheel motor with a sleeve pole shoe gear, comprising a rotor iron core, a rotor sleeve, a stator sleeve, a stator iron core, a permanent magnet, and a flywheel. The rotor iron core, the rotor sleeve, and the flywheel are concentrically embedded from inside to outside to form a whole. The stator iron core and the stator sleeve are concentrically embedded and mounted on a fixed shaft. The stator iron core and the rotor iron core are divided into m sections according to the number of phases along an axial direction. Twelve rotor poles are arranged at equal intervals at an inner side of each phase of rotor iron core. Each phase of stator iron core is provided with eight torque poles and four suspension poles. The torque poles and the suspension poles are selected from pole shoe gears. Control coils are wound on the torque poles and the suspension poles, separately. An axial magnetized permanent magnet is mounted between two phase stators. According to the present invention, the suspension poles and the torque poles are modified into pole shoe gears, which improves the space of a stator groove, effectively improves the density and suspension output of a motor torque, significantly improves the utilization rate of a permanent magnet, decreases the number of permanent magnets, and achieves the effects of saving costs and improving the output.
