1. Traction Drive Speed Reducer for high speed traction motor This TDSR is suitable for high-speed operation like 20000rpm or higher, and it contributes to the downsizing and lightweight of EV drive system. Quietness is better because power is transmitted by traction oil film, no metal contact and vibration in the gear meshing. It can keep high efficiency even if high reduction ratio. 2. High Speed Ball Bearing for EV motors DmN value of this product is up to 14 million and it is suitable for high-speed operation like 30000rpm (eg.bearing ID=35mm) by the using the high speed grease, new cage and new cage material. It makes it possible for EV drive motors to increase the speed greatly.
