Micro motor with riveted electric brush

Abstract

The invention discloses a micro motor with a riveted electric brush, comprising a stator component, a rotor component and an end cover component, wherein the end cover component comprises a cover body, an anode electric brush, a cathode electric brush, an anode electrifying elastic sheet and a cathode electrifying elastic sheet; the end cover component further comprises two metal connectors which are used for electrically connecting the anode electric brush and the cathode electric brush with the anode electrifying elastic sheet and the cathode electrifying elastic sheet correspondingly; the metal connectors are fixedly arranged in the cover body, the anode electric brush and the cathode electric brush are riveted on the respective metal connectors; as the structure that the electric brushes are riveted on the metal connectors replace the structure that the existing lead wire is welded on the electric brush, thus the disadvantages of electric brush deformation caused by welding and low production efficiency can be effectively made up, and the product quality and production efficiency are effectively improved.

Description

technical field [0001] The invention relates to a micro motor, in particular to a micro motor with riveted electric brushes. Background technique [0002] The brush is an important part of a brushed micro motor. Factors such as the elasticity, shape, and arrangement of the brush will affect the performance of a micro motor. [0003] At present, in the production of micro-motor end cover components, the brushes and wires are welded and then put into the end cover, and then the electric shrapnel is welded to the wires. The welding production of wires and brushes is not only inefficient, but also in welding The high temperature in the process can easily cause the brush to deform and reduce its elasticity, seriously affecting the quality of the brush, and then affecting the quality of the micro motor. [0004] In view of the above deficiencies, it is necessary to improve the connection method between the brush of the micro-motor and the shrapnel connected to the electric shrapn...

Problems solved by technology

[0003] At present, in the production of micro-motor end cover components, the brushes and wires are welded and then put into the end cover, and then the electric shrapnel is welded to the wires. The welding production of wires and brushes is not only inefficient, but also in welding The high temperature in the process can easily cause the brush to deform and reduce its elasticity, which seriously affects the quality of the brush, and then affects the quality of the micro motor

[0004] In view of the above deficiencies, it is necessary to improve the connection method between the brush of the micro motor and the shrapnel connected to the electric shrapnel, so as to avoid the problems of brush deformation, reduced elasticity and low production efficiency caused by welding, and improve product quality and production efficiency
