The 4256 Series torque motor from Sonceboz is a brushless rotary actuator designed for medium- and heavy-duty applications. The robust device exceeds applications lifetimes and reduces maintenance costs. The compact unit features high torque boost capability, making it well suited for engine controls applications requiring fast and accurate positioning, such as exhaust gas recirculation valves and intake throttle bodies. It is based on a direct-drive concept with no gears, thus providing fewer moving parts for high reliability in a flat, compact design. It can be driven directly from the vehicle onboard electronic control unit for substantial cost savings compared to brushless actuators with integrated electronics. The device fits applications with extreme temperature and vibration conditions, and it meets the latest EU and U.S. EPA environmental standards. With a boost capability up to 1.5 N·m (1.1 lb·ft), which is 20% higher than the previous generations and even more in 24-V systems, the series can achieve full-stroke positioning times below 100 ms.
