An integrated electric motor and controller reduces weight and provides improved performance of devices associated with internal combustion engines such as EGR valves, turbocharger wastegates and the like. The integrated motor and controller includes an electric motor having an output shaft driving a first segmented wheel and adjacent sensor which provide signals regarding the rotation and direction of rotation of the motor output. The motor also drives a gear train having an output member which bi-directionally either rotates or translates linearly. A position coding feature is disposed on the output member and adjacent sensors provide signals regarding the position of the output member. The sensors drive a microcontroller which in turn drives the electric motor. The sensors, the electric motor, the gear train and the microcontroller are all disposed within a common housing.
