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.
