Abstract

The invention provides a switched reluctance motor with a multidirectional magnetic field characteristic. The switched reluctance motor comprises a stator, an intermediate rotor, a left side rotor, a right side rotor, a shaft, and a cable. The intermediate rotor is installed between the left side rotor and the right side rotor. The stator is installed in space formed by the intermediate rotor, the left side rotor and the right side rotor. The shaft passes through an axle hole of the stator, a through hole of the left side rotor and a through hole of the right side rotor, and is connected witha stator iron core. A leading-out terminal of a stator winding is connected with one end of the cable. The other end of the cable is led to external of the motor. The switched reluctance motor has high power density. Utilization rate of the stator winding is high. Output reluctance torque is large, and since full length of the stator winding is fully utilized to energy conversion, on the premise of a same output rotating speed, a motor with structure of the present invention has the advantages of light quality and small volume, and satisfies a requirement of a low speed dragging occasion well.

Description

technical field [0001] The invention relates to a motor in the field of electrical engineering. Background technique [0002] Various existing switched reluctance motors can be divided into three types according to the distribution characteristics of the internal air gap magnetic field: radial magnetic field, axial magnetic field and transverse magnetic field. In these three different types of switched reluctance motors, the air-gap magnetic field has only a single characteristic, which limits the further improvement of the motor power density. Contents of the invention [0003] The purpose of the present invention is to provide a switched reluctance motor with multi-directional magnetic field characteristics by improving the structure of the existing switched reluctance motor, making full use of the magnetic circuit inside the motor, and then improving the power density and overall performance of the switched reluctance motor . [0004] The purpose of the present invent...
