In the past 3 years, BRS shaft grounding products have been installed on more and more Electric Bus and other commercial vehicles and helped NEV enterprises to improve the product reliability and safety. Recently a major manufacturer King Long will install shaft grounding ring to protect the NEV motor, quantity more than 120 sets.

For electrical damage to the motor bearings, the main reason is the common-mode voltage, some time it will reach dozens V. Especially in start and braking stage. Electric motors in vehicle operate in a range from 1000 to 2000 rpm, and at such speeds the very small damage to the rolling elements will cause serious problem. To solve this headache to most of NEV engineers. BRS promote high performance shaft grounding products to divert the electric current before they build up on the motor shaft.

Since BRS became a major supplier of shaft grounding rings to Subway motor with CRRC 3 years ago. New business with NEV market has seen the most fast growing in recent years. At the same time BRS is continuing to develop new products, involving new material and high efficient manufacturing process, to serve more and more NEV industries in local and overseas market.
