[0011] Preferably, the cross-sections of the first slot and the second slot are both rectangular structures.

[0012] Preferably, a through hole is provided on an outer wall of one side of the rotor.

[0013] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0023] It should be noted that, since the coils in existing motors are usually directly mounted on the stator or rotor, and during the operation of the motor, especially during high-frequency vibration, the wires of the coils may scatter, and the scattering of the coils will affect the normal rotation of the rotor. In this embodiment, the stator coil winding slot 3 and the coil baffle 12 plugged into the stator 2 cooperate with each other, so that the coils wound inside the stator coil winding slot 3 can be limited in multiple directions. The coils are applied with extrusion pressure to avoid the problem of the coils wound on the stator coil winding slot 3 becoming loose or even falling off due to the high-frequency vibration of the motor during the process, thereby ensuring the normal operation of the motor, and through the limiting clamping connection between the first triangular rib 11 and the second triangular rib 14, the plug 13 can be inserted into the required depth according to the thickness of the coil, thereby better applying a limiting force to the coil.

[0024] Specifically, in this embodiment, this scheme mainly includes a stator 2 and a coil baffle 12. When in use, the coil is wound in the stator coil winding slot 3 of the stator 2. After the winding of the coil is completed, the coil baffle 12 is picked up, and the two plug plates 13 on the coil baffle 12 are inserted into the first slot 4 and the second slot 5. The second triangular rib 14 contacts and squeezes the first triangular rib 11. Through the cooperation of the limiting rod 9 and the limiting hole 10, the limiting rod 9 is limited and moved, and the clamping plate 8 is pushed and then squeezes the spring 7. The distance between the coil baffle 12 and the stator 2 becomes closer and closer. The coil baffle 12 limits the coil after contacting it. The second triangular rib 14 is stuck between the two adjacent first triangular ribs 11 to achieve the limitation of the second triangular rib 14, thereby achieving the fixation of the position of the coil baffle 12. The coil can be limited and protected by the coil baffle 12 to prevent the coil from falling off.

[0025] In a further preferred embodiment of the present invention, Figure 1 As shown, there are six stators 2 in total, and the six stators 2 are symmetrically arranged on the inner wall of the motor housing 1, and the cross section of the motor housing 1 is an "I"-shaped structure.

[0026] In this embodiment, the “I”-shaped stator 2 can provide space for winding the coil and limit the position of the coil.

[0027] In a further preferred embodiment of the present invention, Figure 1-4 As shown, the cross-sections of the first triangular rib 11 and the second triangular rib 14 are both right-angled triangle structures, and the inclined surfaces of the first triangular rib 11 and the second triangular rib 14 match each other.

[0028] In this embodiment, by fitting the first triangular rib 11 and the second triangular rib 14 , the second triangular rib 14 can be stuck between two adjacent first triangular ribs 11 , so as to limit the second triangular rib 14 and fix the position of the coil baffle 12 .
