Brushless electric DC motors

Robust, high torque density BLDC for electrical variable valve lift and cam phasing


To optimize combustion dynamically in a real-time response to changing engine speeds and loads. Valve control parameters are now effectively decoupled from the engine speed, which permits a significant improvement in efficiency, performance, and emissions.

Key features

  • Direct drive Brushless DC motors with high-resolution integrated sensors
  • High torque and mechanical power in a compact design
  • HALT tested: -70 to 200°C at 40g RMS
  • High dynamic positioning up to 10,000 RPM
