Electric Motor

Abstract

An electric motor comprising: a rotor having at least one permanent magnet and a first gear arranged on an inner surface of the rotor; a stator comprising at least one electromagnetic coil wound around a section of the rotor; a shaft arranged to be rotatably supported in the electric motor, the shaft comprising a second gear arranged on an outer surface of the shaft; at least one rotary gear member arranged in a space between the first gear and the second gear, wherein the at least one rotary gear member is in meshing engagement with the first gear and the second gear, wherein when current passes through the at least one electromagnetic coil, a magnetic field is generated to cause the rotor to rotate, thereby transferring torque to the shaft through meshing between the first gear and the at least one rotary gear member, and meshing between the second gear and the at least one rotary gear member.
