During the 13th Transmission Symposium China, hosted by the China Society of Automotive Engineers (SAE), Vitesco Technology, a leading international provider of modern drive technologies and electrification solutions, exhibits its new generation of highly integrated electric axle drive for the first time.
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. Utilising the development and industrialisation expertise from the successful EMR3 and previous models, the new platform shows a high level of integration, modularisation, scalability, and standardisation. 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 EMR3, which is used in multiple award-winning vehicles, the EMR4 is even more energy efficient. It weighs 25 percent less at the same power level and is further cost optimised.
"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 which will meet and exceed the requirements of vehicle manufacturers around the world," said Thomas Stierle, Executive Vice President Electrification Technology business unit, Vitesco Technologies.
