Conductive Ring Carbon Fiber Conductive Brush Shaft Grounding Ring for EV Bearing Protection

Description

Product Overview

Volsun VS-RD Series Shaft Grounding Rings

Description
VS-RD series conductive rings solve the problem of motor shaft electrocorrosion by bypass grounding. It is composed of conductive fibers, metal bodies, etc., and is used for electrocorrosion protection of variable frequency motors and their coupled equipment. VS-RD series conductive rings can reduce the induced potential between the bearing and the grounded housing, effectively reduce the damages of electrocorrosion caused by shaft current, protect motor bearings to ensure long-term and stable operation of the motor.
