Motor end cover with good heat dissipation performance

Abstract

The invention discloses a motor end cover with good heat dissipation performance. The motor end cover comprises a motor end cover body, wherein the inside and the outside of the motor end cover body are subjected to rust-proof treatment through a galvanization technology; the motor end cover body comprises a motor end cover bottom and an outer barrel of the motor end cover; at least two straight threaded sections which are not connected with each other are arranged on the inner wall of the outer barrel of the motor end cover; a through hole is formed in the center of the motor end cover bottom; at least one heat dissipation hole which is formed along the circumferential direction of the through hole is also formed between the through hole in the motor end cover bottom and the outer barrel of the motor end cover in a circular manner; a fixed structure is arranged on the outer wall of the outer barrel of the motor end cover; and a thread fixing hole is formed in the fixed structure. The defect that heat in the axial direction of a motor is not easy to dissipate along the axial direction in an accelerating manner during heat dissipation in the prior art is solved; and the motor end cover capable of further accelerating heat dissipation along the axial direction is designed, so that the motor can be subjected to heat dissipation along the circumferential direction during operation, and simultaneously can be subjected to heat dissipation along the axial direction; the heat dissipation is quickened; and a running fault of the motor is avoided.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to a motor end cover with good heat dissipation performance. Background technique [0002] The motor is mainly composed of magnetic core, coil winding, shell, etc., and the motor end cover is an important part of the shell of the motor, and its quality directly affects the normal operation of the entire motor. [0003] Motor (English: Electricmachinery, commonly known as "motor") refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. In the circuit, it is represented by the letter M (the old standard is D). Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit. Its main function is to convert mechanical energy into electrical energy. At present, the most commonly ...

AI Technical Summary

Problems solved by technology

[0028] The purpose of the present invention is to provide a motor end cover with good heat dissipation performance, which solves the problem that heat dissipation in the prior art is often carried out from the side wall, and the heat in the axial direction of the motor is not easy to accelerate the heat dissipation along the axial direction, resulting in Due to the lack of motor failure, a motor end cover that can further accelerate heat dissipation in the axial direction is designed, so that the motor can not only dissipate heat in the circumferential direction during operation, but also dissipate heat in the axial direction, so that the heat dissipation speed is accelerated, avoiding A motor malfunction has occurred
