Brushless electric DC motors

Electric actuators for AMT, CVT, DCT, Torque Management, or EV & Hybrid Transmissions


To reduce CO2 emissions and to maximize driving dynamics for an improved driver's comfort; by smoothly changing the gear ratio of a hydraulic CVT, and enabling the engine to run at its most efficient operating points (BMEP / RPM),

Key features

  • Integrated drive electronics and redundancy encoder
  • Very high positional precision: 8000 positions
  • High torque: up to 2.5 Nm
  • Wide operating temperature: -40° to +150°c
  • Withstands up to 15 g vibration

Your benefits

  • Fast time-to-market for customized solution
  • All-in-one actuator: motor + gears + sensors + electronics
  • Leader and benchmark design in agricultural CVT
  • No maintenance needed: excellent reliability, robustness, and durability in harsh conditions
  • Easy mechanical integration in tight space constraints

Sonceboz smart actuators provide a precise, high-resolution angular setting that determines the reduction ratio of a continuously variable transmission (CVT). Used together with a redundant sensor, it is part of a safety circuit in the vehicle. Thanks to a seamless waterproof and dustproof (IP 6K9K) design, they can withstand severe vibrations and electromagnetic interference, operate in extreme temperatures, featuring an expected lifetime of 20,000 hours. They easily integrate into automatic manual transmission (AMT) searching for an efficient linear electric actuator that features a CAN communication bus.
