Problems solved by technology

[0004] In the prior art, conductive fibers are generally evenly bonded to the inner circumference of the shell of the conductive ring through conductive glue. If the conductive fibers want to achieve sufficient fixing strength, thicker conductive glue must be applied, resulting in the thickness of the entire conductive ring. Cannot meet the requirements of new energy vehicle motors

Abstract

The invention discloses an ultra-thin side circuit conductive ring. The ultra-thin side circuit conductive ring comprises an annular outer cover and conductive elements arranged on the annular outer cover; the conductive elements comprise at least one conductive fiber bundle and a conductive sleeve for fixing the conductive fiber bundles; a fixing part used for fixing the conductive sleeve is arranged on the annular outer cover; and the conductive fiber bundles and a motor shaft are in interference contact. By adopting a novel structure, the problem existing in realization of stability and fastening of the conductive fiber bundles on the annular outer cover under relatively thin thickness requirement is solved; and fixation and durability of conductivity are fully guaranteed.

Description

technical field [0001] The invention relates to the field of motors, in particular to a conductive ring of a motor. Background technique [0002] When the frequency conversion of the new energy vehicle motor is performed, the voltage on the shaft will increase, and the shaft voltage will be released through the bearing through the current. When the current is released, the surface of the bearing race and the ball is galvanically corroded, and the corrosion process is slow. In this process, the driver will feel that the power of the new energy vehicle is getting smaller and smaller. When the car is lying down, the bearing of the car motor has been damaged, which is manifested by blackening of grease, melting pits on the surface of the bearing race and balls, and the particles in the melting pit layer are sealed in the bearing by the sealed bearing. These reasons eventually lead to the failure of the bearing Shorter lifespan. [0003] Therefore, in order to prevent the occu...
