Single-winding non-bearing magnetic flux switching permanent magnetic motor

The invention belongs to the technical field of a motor, and relates to a single-winding non-bearing magnetic flux switching permanent magnetic motor. The single-winding non-bearing magnetic flux switching permanent magnetic motor comprises a stator iron core, a rotator iron core, permanent magnets embedded in the middle of stator teeth, and concentrated windings. A stator and a rotor are both of double-salient pole structures. The single-winding non-bearing magnetic flux switching permanent magnetic motor is characterized in that the stator iron core is composed of six U-shaped laminations; a permanent magnet capable of tangential alternative magnetizing is embedded between every two laminations so that a stator tooth which is axisymmetric is formed; the stator teeth are provided with the concentrated windings, the end portions of the windings are quite small, and the windings, which are opposite to each other in terms of space, on two stator teeth form a phase so that a three-phase winding is formed; and the excitation of winding currents is of a radial excitation mode, each winding is independently controlled, the winding currents can perform bidirectional flow in positive and negative directions, the current size can be controlled according to needs, and the currents has the same phase as a back electromotive force. The single-winding non-bearing magnetic flux switching permanent magnetic motor has the advantages of high speed, large power, high efficiency, high power density, high operation stability, high reliability, and adaptability to an AC operation mode.
