Johnson Electric is the technology and market leader for turbo wastegate motion solutions. Increasingly vacuum-actuation of the turbo wastegate does not provide adequate dynamic response and position control in order to meet the increasingly stringent fuel economy and emissions standards.
Johnson Electric's family of turbo wastegate motor platforms are designed for high dynamic response and reliable operation in the most stringent operating modes and environments. They can tolerate temperatures up to 160°C and vibration levels of 50g in all directions. Johnson Electric's wastegate motors are differentiated by high torque density delivering industry-leading torque per unit mass or volume. Motors are custom engineered for low cogging torque to ensure proper valve fail-safe operation when needed and lower inertia to allow faster dynamic response.
