Automotive

We have long been a competent development partner to our customers in the automotive industry. We offer structured development processes, short time-to-market and the desired functionality at low costs. Virtually no other organization can compete with our comprehensive mechatronic knowledge of the entire drive train. Our years of experience in electric mobility and hybrid drives are also raising the bar in the industry.

Our drives break new ground and impress customers with maximum power density, limited weight and outstanding efficiency. Our catalog includes traction drives for hybrid and electric vehicles, generators and motors for function-critical auxiliary equipment and products such as servo pumps and oil pumps. Our product line is completed with modified power electronics and smart control software.
