The stator consists of three parts: the stator core, the stator windings, and the 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 magnetic lines of force within this rotating magnetic field, thereby generating or outputting current. Currently, when troubleshooting existing electric motor stators manually, the compact structure makes disassembly difficult, resulting in a time-consuming and labor-intensive repair process. Furthermore, reassembly after repair is inconvenient. Summary of the Invention

[0010] S1: The stator coil is wound by a stator coil fixing frame, and each stator coil fixing frame is an independent structure. The wiring groove set on the top of the rotor shaft sleeve is used for stator coil wiring.
[0011] S2: After the stator body end cover is installed, the limiting plate at the bottom of the stator body end cover will fit against the side of the rotor shaft sleeve, so that the wiring groove forms a relatively sealed cavity.
