Embodiment Construction
[0026] Such as Figure 1 ~ Figure 3 As shown, the permanent magnet motor includes a stator base 1 , a stator core 2 , a stator winding 3 , a permanent magnet 7 , a rotor core 6 , a rotor shaft 4 and a bearing 5 . A stator core 2 is fixed inside the stator frame 1, and a stator winding 3 is arranged on the stator core 2; wherein, the stator frame 1 can be fixed by a conventional motor installation method, and the stator core 2 is a part of the magnetic circuit of the motor , The stator winding 3 is generally a three-phase winding. The rotor shaft 4 is fixedly arranged in the stator frame 1 through the bearing 5, and the rotor core 6 is fixedly arranged on the rotor shaft 4, and a permanent magnet 7 is arranged on the rotor iron core 6, and the magnetization direction of the permanent magnet 7 is radial, The polarities of the permanent magnets 7 are alternately arranged, and the rotor shaft 4 can drive the rotor core 6 and the permanent magnets 7 to rotate around the axis.
