Abstract: An electric motor contains a mechanical mechanism that causes a rotor to move in an epitrochoidal path. Disposed around the epitrochoidal path are stators that may impel or force the rotor to rotate. The mechanical mechanism that creates the epitrochoidal path may consist of an output shaft with an eccentric lobe, where the rotor revolves around the eccentric lobe. A fixed mounted sun gear may engage a ring gear mounted to the rotor to cause the epitrochoidal motion. Some embodiments may have two or more rotors, and may include controllers with feedback sensors to operate the electric motor at a specific speed or to control the speed as defined in a speed profile.
