Problems solved by technology

[0002] The principle of the switched reluctance motor is that the magnetic circuit is always closed to the path with the smallest reluctance. The ideal magnetic circuit path is that the magnetic circuit starts from the energized salient pole of the stator core, passes through the air gap, and then passes through the salient pole of the rotor core. Then pass through the yoke of the rotor core, then pass through the salient poles of the rotor core, and then return to the energized salient poles of the stator core through the air gap; but due to the limitation of the iron core magnetization saturation and the characteristics of the magnetic circuit diverging outside the magnetic poles, some The magnetic circuit will deviate from the design path closure, and even generate reverse torque, resulting in a decrease in magnetic energy utilization and a decrease in output torque
[0003] It is further understood that the magnetic circuit is always concentrated to the magnetic poles. Since the salient poles of the switched reluctance motor have no magnetic pole polarity, the magnetic circuit cannot be concentrated to it, resulting in the low utilization rate of the magnetic energy of the existing switched reluctance motor.
