Abstract

To optimise the needed space, weight and functional integration, BMW Group and PSA Peugeot Citroën switched to brushless DC technology for the fully variable valve control in the process of further developing the “TwinPower” turbo engine. Sonceboz Automotive SA, in cooperation with Moving Magnet Technology, the subsidiary for research and advance development in the area of actuators and sensors, has developed a suitable new brushless DC motor with redundant, digital angle measurement. The fully automated production of such a complex and highly stressed electrical actuator was and is at least just as challenging as its development and qualification.
