Specific implementation mode
The utility model is further described with reference to the accompanying drawings and detailed description.
Embodiment 1：In embodiment as shown in Figures 1 to 5, a kind of brushless motor stator and shell part structure, including method
Blue disk 1, stator 2 and shell 3, ring flange are arranged on the shell；
The ring flange be equipped with disk through-hole, shell be equipped with for allow rotor shaft by shell through-hole 31；
The housing interior side-wall is equipped with several screens protrusions 5, and stator, which is equipped with, to be corresponded with several with screens protrusion
Screens straight slot, screens protrusion is stuck in corresponding screens straight slot.
The housing interior side-wall is equipped with several positioning protrusion 6 for being used to support stator, and positioning protrusion contacts stator, in method
Blue dish axle is upward：Ring flange, stator and any positioning protrusion are sequentially arranged.
The surface of the positioning protrusion and stator contact is a flat surface, and each positioning protrusion is circumferentially sequentially distributed along ring flange.
The length direction of the screens protrusion is parallel to stub shaft to each screens protrusion is circumferentially divided successively along ring flange
Cloth.
The ring flange includes big disk body 11 and small disk body 12, and small disk body is in shell, and small disk body contacts stator, shallow bid
External side wall is equipped with annular groove 13, and shell is equipped with several handle holes 4, is equipped in handle hole at least one for being caught in ring
Riveting body 41 in connected in star.The riveting body is an integral molding structure with shell, and the riveting body number in each handle hole is
