BorgWarner says its compact brushless actuator, designed to optimize engine performance and reduce nitrogen oxide emissions for on- and off-road commercial diesel vehicles, features the latest advancements in electronic rotary actuators. From turbocharger and exhaust gas recirculation systems to exhaust brake applications, the compact brushless actuator is designed with proprietary smart electronics to control various complex engine emissions and performance systems.

To deliver a combination of compact size and higher torque, BorgWarner says its engineers optimized the brushless DC motor and gear drive using an advanced heavy-duty gear train to withstand the harsh duty cycles of off-road environments. The device is designed to perform in temperatures up to 284 degrees Fahrenheit and provide continuous operation up to 266 degrees Fahrenheit; for even higher temperature capability, two water cooling options are available.

BorgWarner says that by using electric rather than pneumatic actuation, response time is reduced to 150 milliseconds. The actuator, available for both 12V and 24V systems, communicates via a controller-area network and features proprietary “smart seating” algorithms to adapt to changes in mechanical components over time due to wear or temperature, while proprietary advanced power management functions optimize performance while protecting the actuator from extreme operating conditions. The fully sealed compartment is designed to protect electronics even if fully immersed.
