We have developed a multi-stage reduction gear suitable for electric vehicles (EVs) by utilizing our proprietary processing technology. Equipping it with a low-output motor and reducing battery capacity leads to reduced heat generation and power consumption, which has been confirmed to be very effective for vehicles powered by motors. This reduction gear is not only targeted at automobiles (EVs, FCVs, PHVs) but also serves as an effective product for new modes of transportation powered by motors (small mobility) that are expected to see significant market expansion in the future, aiming for energy efficiency. 【Benefits of Developing a Dedicated Reduction Gear】 1. Utilization of the efficient parts of the motor 2. Weight reduction 3. Effective use of space 4. Possibility of EV conversion for vehicles without MT settings *For more details, please refer to the PDF materials or feel free to contact us.
