| Zusammenfassung: | A brushless motor comprises a stator and a casing sleeved on the periphery of the stator, a limiting structure is arranged between the stator and the casing, and the limiting structure comprises a boss arranged on one of the periphery of the stator and the inner wall of the casing and a groove arranged on the other one of the periphery of the stator and the inner wall of the casing. The boss and the groove are matched in shape to limit circumferential rotation of the stator relative to the casing. The groove continues to be recessed in the recessed direction to form a first receiving groove, the boss is recessed inwards to form a second receiving groove matched with the first receiving groove, the limiting structure further comprises a fastening piece, and after the stator and the machine shell are assembled, the first receiving groove and the second receiving groove are spliced to form a receiving groove for receiving the fastening piece. And the fastener penetrates through the receiving groove to lock the b |
