Embodiment Construction
[0045] The present invention is further described below in conjunction with accompanying drawing.
[0046] refer to Figure 1 to Figure 7 , Transition asynchronous start permanent magnet synchronous motor is mainly composed of stator parts and rotor parts. The rotor part is installed in the stator part, and the transitional asynchronous start permanent magnet synchronous motor adopts a transitional starting mode or a direct starting mode.
[0047] The stator part is mainly composed of the stator core 8, the stator winding 9 and the motor frame, the stator winding 9 is installed on the stator core 8, the stator core 8 and the stator winding 9 are installed in the motor frame, the inner cavity of the motor frame A bearing is respectively assembled on both axial sides, which are bearing one 19 and bearing two 20 respectively.
[0048] The rotor part is mainly composed of a rotating shaft 1, a buffer pad 1 2, a buffer pad 2 11, an open retaining ring 14, a magnetic isolation bush ...
