Vitesco Technologies Reveals Next Generation Electric Axle Drive – EMR4

Vitesco Technologies has showcased its new generation   of highly integrated electric axle drive the EMR4 at the 13th Transmission Symposium China,

The EMR4 (Electronics Motor Reducer) offers high power density, compact dimensions, and low weight. The comprehensive platform covers power requirements from 80 kW to 230 kW. Utilizing the development and industrialization expertise from the successful EMR3 and previous models, the new platform shows a high level of integration, modularization, scalability, and standardization. This allows vehicle manufacturers worldwide to offer different power levels of the drive-in one model without having to touch interfaces or mounting points. Compared to the award-winning EMR31, the EMR4 is even more energy efficient. It weighs 25 percent less at the same power level and is further cost-optimized.

“Electromobility is picking up speed. The key to supporting this megatrend lies in high efficiency and reliability as well as affordability for high-performing electric drive systems. We have anticipated this with the EMR4 design. This new axle drive platform offers a combination of benefits that will meet and exceed the requirements of vehicle manufacturers around the world”, said Thomas Stierle, Executive Vice President Electrification Technology business unit, Vitesco Technologies.

"Although EMR3 already set ambitious benchmarks in weight, compactness, and power density, EMR4 surpasses the current third generation. It delivers up to 5 percent increased efficiency of the whole axle drive (compared with the predecessor generation), significantly greater power scaling between 80 kW and 230 kW, and substantial cost reductions. “This is the result of consistent system optimization on detail level within numerous effect chains in the axle drive”, said Gunter Mühlberg, head of Product Management Axle Drives at Vitesco Technologies
