Abstract
An electric motor or actuator having a housing and a stator mounted to the housing about a central axis. The actuator includes a rotor that is mounted within the housing in surrounding relationship to the stator for moving in an orbiting manner with respect to the stator poles in response to the magnetic force. The rotor has an axis that is eccentrically positioned from the central axis by a distance e.sub.1 and further includes a double eccentric that is mounted in rotating, surrounding relationship to the rotor and drivingly coupled thereto for transmitting the motion of the rotor to a ring gear. A stationary gear is attached to the housing and is mounted in surrounding relationship to the ring gear. The stationary gear includes a set of gear teeth which react with a coacting set of gear teeth on the ring gear, thus causing the ring gear to turn in response thereto. The rotating motion of the ring gear is transmitted to an output gear which is mounted in surrounding relationship to the stator gear and to the ring gear.
