In order to solve the above-mentioned technical problem, a kind of brshless DC motor end cap provided by the utility model, including bottom wall and
Positioned at the side wall of bottom wall side annular；The side wall has several axial positioning ribs, the axial direction close to the side of bottom wall
Positioning bar there is the muscle body of bar shaped and the engaging body of bar shaped positioned at muscle body side, the height of the engaging body is less than muscle body
Highly.The end cap periphery of the utility model motor with novel arrangement plastic housing is provided with a plurality of axial positioning rib, more with stator card slot
Coordinate well, and coordinated by skeleton, the influence of the shrinkage of material to cooperation greatly reduces, and improves assembly precision.
Preferably, the bottom wall is equipped with the boss of annular；The sunk area at the center of the boss constitutes bearing chamber.
Preferably, also there is the ring-shaped step positioned inside on the boss madial wall.
Preferably, the boss madial wall is equipped with several axial reinforcing ribs；The axial reinforcing rib both ends point are certainly
The lower end of the boss of annular extends to the upper end of boss.The utility model bearing chamber be equipped with fixing muscle, directly with bearing tight fit,
Traditional silica gel bearing housing structure is no longer used, the problem for being inconvenient to coordinate and coordinating deviation big is improved.
Preferably, the bottom wall is additionally provided with a pair of of partition board positioning column, and the partition board positioning column described in a pair is evenly distributed in
The outside of boss.
Preferably, the bottom wall is octagonal, and the axial positioning rib is four.
（Three）Advantageous effect
A kind of brshless DC motor end cap provided by the utility model, has the following advantages：
1, the end cap periphery of the utility model motor with novel arrangement plastic housing is provided with a plurality of axial positioning rib, with stator card
Slot preferably coordinates, and is coordinated by skeleton, and the influence of the shrinkage of material to cooperation greatly reduces, and improves assembly essence
