Embodiment Construction
[0035] see figure 1 and figure 2 , the present invention includes a stator 1, a rotor 2, a rotating shaft 6 and an end cover 7, the stator 1 and the end cover 7 are fixedly connected together, and the end cover 7 is fixedly installed on the base 8. The rotor 2 is coaxially sleeved inside the stator 1 , and the rotating shaft 6 is coaxially fixed at the center of the rotor 2 . There is an air gap between the inner wall of the stator 1 and the outer wall of the rotor 2, and the thickness of the air gap is related to the power level of the motor, the selected permanent magnet material, and the processing and assembly process of the stator 1 and rotor 2. Both the stator 1 and the rotor 2 are formed by laminating silicon steel sheets with a thickness of 0.35 mm, and the lamination coefficient is 0.95. The rotating shaft 6 is composed of non-magnetic materials.
[0036] See 1 and image 3 , The stator 1 is composed of stator teeth 9 , stator slots 10 , and stator yoke 11 . A st...
