Abstract: Magnetically-assisted mechanical gear systems and other power transmission systems, and related methods of operation and assembly, are disclosed herein. In an example embodiment, such a system includes a driving gear, a driven gear, and a first magnetomotive force (MMF) source that generates a magnetic flux. A first portion of the flux is communicated between at least one driving gear teeth and at least one driven gear teeth so that one or more magnetic forces are exerted between the gears. When the first rotational movement of the driving gear alternates from being in the first rotational direction to being in a third rotational direction opposite the first rotational direction, then the driven gear is driven by the one or more magnetic forces so that the second rotational movement also alternates, and a first amount of backlash movement between the driving and driven gears is avoided or reduced.

Abstract: A rotor that includes a rotor core assembly secured to a shaft. The rotor core assembly includes a magnet and an end cap secured to an end of the magnet. Each of the magnet and the end cap has a bore into which the shaft extends. The end cap forms an interference fit with the shaft. The magnet forms a clearance fit with the shaft and an adhesive is located in the clearance between the magnet and the shaft. Additionally, a method of manufacturing the rotor. The method includes inserting the shaft into the bore of the end cap. An adhesive is then introduced into the bore of the magnet and the shaft is inserted into the bore of the magnet so as to cause adhesive to be drawn into the clearance defined between the magnet and the shaft.
