A active steering apparatus includes a housing, an input shaft, an output shaft, and an electrical motor. The electric motor has a stator fixed to the housing and a rotor. A first gear set interconnects the input shaft and the output shaft and includes a sun gear fixed to an end of the input shaft, a ring gear fixed to the output shaft, and a plurality of planet gears positioned between and interconnecting the ring gear and the sun gear. A second gear set is mounted onto the rotor and interconnects the ring gear and the housing such that rotation of the rotor relative to the housing imparts movement of the ring gear relative to the housing.
