An upper flange 21 and a lower flange 31 are formed on the outer periphery of the upper end of the upper stator support 2 and the outer periphery of the lower end of the lower stator support 3, respectively. When the upper stator support 2, the lower stator support 3, and the stator core 1 are installed, the upper flange 21 and the lower flange 31 are respectively fitted and fixed to the inner side of the upper end face and the inner side of the lower end face of the stator core 1.

The upper stator support 23 and the lower stator support 33 are respectively provided on the end face of the three-end face. The lower end face of the upper stator support 2 around the upper stator support 23 is provided with an upper support protrusion 24, and the upper end face of the lower stator support 3 around the lower stator support 33 is provided with a lower support protrusion 34. When the upper stator support 2 and the lower stator support 3 are installed and fixed, the upper support protrusion 24 and the lower support protrusion 34 fit together. Since the upper support protrusion 24 and the lower support protrusion 34 protrude from the upper stator support 2 and the lower stator support 3, a heat dissipation gap 4 is formed between the upper stator support 2 and the lower stator support 3.

[0021] like Figures 1 to 5 As shown, upper fixing pins 25 and lower fixing pins 35 are formed on the outer periphery of upper heat dissipation hole 23 and lower heat dissipation hole 33, respectively. When upper stator bracket 2 and lower stator bracket 3 are fixedly installed, upper fixing pin 25 passes through lower heat dissipation hole 33 and lower fixing pin 35 passes through upper heat dissipation hole 23. There are three upper fixing pins 25 and three lower fixing pins 35. The upper fixing pins 25 and lower fixing pins 35 are distributed at intervals on the outer periphery of upper heat dissipation hole 23 and lower heat dissipation hole 33, and the positions of upper fixing pins 25 and lower fixing pins 35 are also distributed at intervals.

The insulated end plate 5 for the outgoing line and the insulated end plate 6 for the Hall effect are located on one side of the upper stator support 2 and the other side of the lower stator support 3. The winding 7 is fixed on the stator core 1 outside the insulated end plate 5 for the outgoing line and the insulated end plate 6 for the Hall effect.

[0023] To elaborate further, such as Figures 1 to 5 As shown, several upper fixing grooves 26 and lower fixing grooves 36 are respectively provided on the upper end face of the upper stator bracket 2 and the lower end face of the lower stator bracket 3. The upper fixing grooves 26 and lower fixing grooves 36 are used for bolts to pass through and fix the upper stator bracket 2 and the lower stator bracket 3 together.

[0024] To elaborate further, such as Figure 1 As shown, stator steel sleeves 8 are fixedly inserted into the upper shaft hole 22 and the lower shaft hole 32, and the stator steel sleeves 8 serve to support this embodiment.
