Abstract
A brush device, comprising a brush holder and a brush assembly, for providing electrical contact with a moving part while suppressing electrical noise generated during the interaction of the brush device with the moving part. The brush holder includes a housing adapted to receive a brush assembly within the housing, and noise suppression arrangement, mounted on the housing and electrically connected to a brush assembly, for suppressing electrical noise generated during the interaction of the brush assembly and the moving part by providing an inductive impedance in the electrical path of the brush assembly. The brush holder may further include a connector cap, electrically connected to the noise suppression arrangement, adapted to provide a mating connection between the noise suppression arrangement and an external connector. The brush assembly is positioned within the housing such that sliding electrical contact is made with the moving part.
