Smaller, higher speed motors with large gear reduction ratios create unique design challenges to ensure top performance of the EV drivetrain. Many factors influence reduction gearing performance, which must be considered throughout the design process, including:

Speed requirements
Cost
Weight, size and packaging requirements
Efficiency
Reliability
Noise, vibration and harshness (NVH)

We work with you to help balance these requirements to your unique design objectives, utilizing our existing know-how to optimize the gear design for your application.

Our gear modeling capabilities help EV customers solve their challenges of compact, lightweight and low noise EV drivetrains, while providing maximum efficiency and range.

Our solution development methodology helps customers minimize their investment to optimize their EV gearing design. Using simulation, modeling and solution analysis to evaluate gear performance across various drive cycles, we leverage our proprietary manufacturing know-how to design for key manufacturing outcomes including wear resistance, hard finishing, and quality.

EV gearing design and manufacturing is part of our complete portfolio of ePowertrain and eMobility solutions, including integrated gear and motor shafts, EV reduction gearing, and EV differentials, all designed to manage the unique torque requirements of EVs.
