Abstract
The utility model discloses a motor end cap, relating to the field of fan manufacturing and process. The motor end cap comprises a cover plate and an inner ring. The cover plate is centrally provided with a shaft hole. A plurality of positioning flanges are arranged under the cover plate to ensure the positions of a brush box plate and a bearing chamber. A ring-shaped projection, which is centered by the axis of the shaft hole, is arranged above the cover plate, forming an inner cavity, and used for placing a bearing box. The inner wall of the projection is provided with barbs for fixing the bearing box so as to prevent the bearing box from sliding out. The inner ring is connected with a casing of a motor to ensuring the coaxality of the motor end cap and the casing. The inner wall of the inner ring is provided with bosses. The cover plate is connected with the inner ring. The motor end cap is made of aluminium alloy by die-casting. According to the utility model, the accuracy and reliability of the motor are improved, and the whole end cap is opened, so that the ventilation and heat radiation effects of the motor are greatly improved.
