Abstract

An integrated motor end cover comprises an end cover body and further comprises two groups of inductor fixing clamps integrally formed with the end cover body, a wire outlet clamp and four groups of concave guide rails for installing electric brushes. The middle of the end cover body is provided with a fixing column or a bearing chamber for fixing a motor shaft, the circumference of the end cover body is provided with three hole columns for penetrating mounting screws, the end cover body is provided with a plurality of heat dissipation holes, a plurality of reinforcing ribs and two grooves for installing grounding pieces, the fixing column is provided with reinforcing ribs, a spring is embedded in the fixing column, strength of the position is improved, and the risk of cracking of plastic entering a shaft can be reduced. The integrated motor end cover has the advantages of high integration degree, less parts and materials, light weight, small size, short axial distance, good heat dissipation, high reliability and long service life.

Description

technical field [0001] The invention relates to a motor, in particular to an integrated motor end cover. Background technique [0002] The motor of prior art has following defective: [0003] A. The normal operation of the DC motor is inseparable from the brush basin, brush holder, connecting piece and two end caps, etc., so there are many materials and parts; [0004] B. The function is simple, and each part undertakes a single function: the end cover can only support the stator and place the bearing; the brush basin holds the brush holder and electrical components; [0005] C. Many processing procedures: In addition to multiple processing procedures for each part, it is also necessary to increase the installation and positioning of multiple brush holders and connecting pieces. [0006] The heat dissipation of the connecting piece is not good enough: the structure of the brush basin and the connecting piece are embedded inside the body of the brush basin, which is not con...
