[0002] The stator is the stationary part of the motor. The stator consists of three parts: a stator core, a stator winding, and a frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by the magnetic lines of force in the rotating magnetic field to generate (output) current.
[0003] In the traditional stator assembly, the stator core is fixed to the outer shell by bolts or rivets. During long-term use, the vibration of the motor easily shakes off the rivets or bolts, causing the stator winding and the stator core to deform. Secondly, the installation is rather troublesome and requires individual installation and fixation. For this reason, we provide a stator assembly of an AC motor. After installing the stator winding on the stator core, the stator core is slidably fixed on the inner support frame through iron core sliders, and the outer side is slidably connected to the stator core through frame sliders, which can facilitate its quick installation and fixation and effectively make up for the above problems.
