Johnson Electric develops industry-leading air valve motion solutions to enhance fuel efficiency, drivability, and safety. Current product platforms include engine management applications such as electronic throttle controls (ETC), exhaust gas recirculation (EGR), variable geometry turbo (VGT) and variable-length intake manifold (VLIM) and others.
Johnson Electric's air control valve motor platforms are differentiated by high torque density delivering industry-leading torque per unit mass or volume. In addition, they are custom engineered for low cogging torque to ensure proper valve fail-safe operation and lower inertia to allow faster dynamic response. Johnson Electric’s family of air control valve motors includes a line of compact motors using high performance ferrite magnets avoiding the uncertainties associated with rare earth magnets.
To satisfy the durability, efficiency and environmental requirements of the most demanding applications Johnson Electric provides brushless motor platforms with integrated electronics custom engineered for each application.
