- Technology leads to a new class of actuators for systems in combustion, hybrid and electric vehicles, including park lock and disconnect applications - Optimized brushless DC motor with integrated electronics offers industry-leading dynamics and durability to latest generation of AWD coupling AUBURN HILLS, Mich., Aug. 22, 2019 /PRNewswire/ — The latest generation of BorgWarner’s all-wheel drive (AWD) coupling has been optimized with a compact brushless direct current (BLDC) motor and highly integrated electronics. The resulting actuator unit has very high durability and weight savings of approximately 15 percent in comparison to a conventional AWD coupling. The lightweight, high performance design has best-in-class response times, torque density and accuracy. As a result, vehicle handling, stability and traction are enhanced. At the core of the coupling is a patented 6-piston centrifugally controlled piston pump that both creates and controls system hydraulic pressure. Now powered by BorgWarner’s in-house design of BLDC motor, the latest generation coupling is a key enabler for Eco mode systems due to its high stop/start capability. Motor control algorithms, ...
