Description

Electric brush assembly

Technical Field

The utility model mainly relates to the technical field of electric brushes, in particular to an electric brush assembly.

Background

A brush is a conductive member that makes sliding contact with a moving member to form an electrical connection. The brush is used in a commutator or a slip ring as a sliding contact body for leading and leading current. It has excellent electric, heat and lubricating performance, certain mechanical strength and the instinct of inhibiting commutation spark. Almost all direct current motors as well as commutating motors use brushes, which are important components of the motor. However, in the existing traditional carbon brush assembly, a copper wire is connected with the carbon brush and welded with a conducting strip, the process is complex, a large amount of manual operation is used, and the quality is unstable.
