The Air Control Valve (ACV) is a critical component in meeting the increasing demand for better vehicle fuel economy, lower emissions and improved drivability. For ACV applications, system actuators must have high power density to provide sufficient torque under all engine conditions and across a wide range of ambient temperatures. Reliable performance and durability of the ACV electric motor technology is a critical element in engine performance.
Johnson Electric's air control valve platforms provide 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 air control valve motion platforms include a line of compact motors using high performance ferrite magnets avoiding the uncertainties associated with rare earth magnets.
