Abstract:
An apparatus comprising:a fixed core; a central shaft having a central axis, the central shaft being rotatable about the central axis and disposed within the fixed core; at least one body having a body axis and coupled to the central shaft, the at least one body being rotatable about the body axis, the body axis being parallel to the central axis; a roller having an annulus and a roller axis, the roller being rotatable about the roller axis, the roller axis being parallel to the central axis, the annulus further having an inner surface and the at least one body engaging the inner surface of the annulus; a regulator having a regulator axis, the regulator being rotatable about the regulator axis, the regulator axis being parallel to the central axis, the regulator engaging the inner surface of the annulus so that the roller is rotatable about the roller axis; and drive means connecting the roller to the fixed core so that when the at least one body rotates about the body axis the roller orbits around the fixed core and causes the central shaft to rotate about the central axis.
