Description

technical field [0001] The invention relates to electrical machines 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 radial and transverse magnetic field characteristics, which has high stator winding utilization rate and high power density. [0004] The purpose of the present invention is achieved like this: [0005] A switched reluctance motor with radial and transverse magnetic field characteristics of the present...
