The BLDC smart brushless dc actuator from Sonceboz is an electronically commutated actuator designed for controlling emissions in large diesel engine applications. High torque values are offered in a compact housing, suitable for integration in a narrow engine compartment. The BLDC actuator features CAN bus control electronics and operates between 9 and 32 V. In the event of power failure, a return-to-zero spring and customizable failsafe position are included. The brushless actuator delivers short positioning times while providing accuracy for finer flow control and acts as a modular stand-alone unit with design flexibility and a torque range for valves requiring smart actuation. Applications in medium- and heavy-duty engines include air admission and charging and exhaust gas applications; operating temperature range is -40 to +140°C (-40 to +284°F).
