ABSTRACT:
An electronic throttle assembly uses a torque motor and mechanical system to position the throttle. The assembly is configured to keep the throttle slightly open during times of electrical power failure to the torque motor. Inherent electromagnetic qualities of the torque motor provide a reluctance torque that varies depending on internal stator/rotor geometry and is present in the absence of electrical power to the motor. A mechanical system provides a counter torque. Aligning the throttle to the desired slightly open position at a point where the reluctance torque is countered by the mechanical torque, allows an engine controlled by the throttle to continue to operate even if electrical power to the torque motor is lost.
