A wire brush for a slipring includes a contact section, from which a stabilizer arm is extending backwards towards the brush block of the slipring. The stabilizer arm holds a friction section, which is in friction contact with the contact section at a friction contact area. Such contact, in operation, generates internal friction within the brush when the brush is moved and, therefore, suppresses oscillations of the brush.

A bearing isolator and explosion-proof current diverting device may be configured to dissipate an electrical charge from a rotating piece of equipment to ground, such as from a motor shaft to a motor housing. One aspect of an explosion-proof current diverter ring may include a stator that may be mounted to the equipment housing and a rotor that may be mounted to a shaft. The rotor may rotate with the shaft. A conductive assembly may be positioned in a radial bore formed in the stator such that the conductive assembly contacts the rotor to conduct electricity from the shaft to the housing through the explosion-proof current diverting device. The explosion-proof current diverting device may be configured to define a flame path to achieve various explosion-proof certifications.

A brush device having the longitudinal direction of a coil shaped coil spring aligned with the face of a brush holder, in which one end of a support post at the surface of a brush base is formed as a hollow cylinder and a projection at the other end is insert molded into the brush holder. There is a step on the support post. The step and the brush holder receive a cover plate which, when viewed from a direction perpendicular to the face of the brush holder, covers a winding of the coil shaped coil spring. One end of the support post is fixed to the surface of the cover plate by spreading the end of the hollow cylinder of the support post.
