[0022] Example one
[0023] Reference figure 1 with figure 2 , The new switched reluctance motor in this embodiment is mainly composed of a coaxially arranged rotating shaft 6, a rotor core and a stator core, and the remaining part in the middle is an air gap. The stator core is made of integral stator poles 2 and Cylindrical stator yoke 1 is formed, stator poles 2 and stator yoke 1 are laminated by silicon steel sheets. Several stator poles 2 are distributed on the inner surface of stator yoke 1 at equal intervals in the circumferential direction. The rotor core is made of An integral rotor pole 4 and a cylindrical rotor yoke 5 are formed. Several rotor poles 4 are distributed on the outer surface of the rotor yoke 5 at equal intervals in the circumferential direction. The rotating shaft 6 is magnetically conductive and penetrates the rotor yoke 5. A stator winding 3 is provided in the gap formed between adjacent rotor poles 2 on the stator core. The stator winding 3 is a copp...

[0024] Example two
[0025] Reference image 3 The difference between this embodiment and the first embodiment is that the two sides of the rotor pole 4 protrude outward in an arc shape, and the two sides are arranged symmetrically with respect to the center of the rotor pole 4, and the two sides of the arc shape L 1 , L 2 Make the rotor pole 4 a trapezoid as a whole, and the angle between the arc tangent on the side of the rotor pole 4 and the vertical line of the upper and lower points on the same side is the deflection angle θ, and the deflection angle θ is 0° ~45°. With this arrangement, the motor vibration and noise have been significantly improved, and the loss under this scheme has also been reduced. Since the loss is reduced, the efficiency is improved, the heat density is reduced, and the temperature rise is reduced. Therefore, the structure is also suitable for the occasion in the first embodiment, and the loss is reduced and the power density is increased, which helps ...

[0026] Example three
[0027] Reference Figure 4 The difference between this embodiment and the first embodiment is that the two sides L of the rotor pole 4 1 , L 2 Are two straight lines inclined parallel to one side, and the angle between the vertical line of the side of the rotor pole 4 and the upper and lower points on the same side is the deflection angle θ, the deflection angle θ is 0° ~45°. In this way, the vibration, noise and temperature rise of the motor can be significantly improved. Based on the balanced performance of the structure on vibration, noise and temperature rise, it can be used in more sophisticated, more complex and more demanding occasions, such as military industry, aerospace and ships.
