Intake Manifold Throttle Valves (IMTV) are a critical component in meeting the increasing demand for better vehicle fuel economy, emissions and drivability. For throttle valve applications, the actuation solutions 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 IMTV electric motor is a critical element in engine performance.
Johnson Electric's IMTV solutions are custom designed for high dynamic response and reliable operation in the most stringent operating modes and environments. The motors can tolerate temperatures up to 160°C and vibration levels of 50g in all directions. Johnson Electric's ETC motors are also differentiated by high torque density delivering industry-leading torque per unit mass or volume. In addition Johnson Electric's family of IMTV motors 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 IMTV motors includes a line of compact motors using high performance ferrite magnets avoiding the uncertainties associated with rare earth magnets.
