Flux focusing magnetic gear assembly using ferrite magnets or the like

摘要

The present invention relates generally to a flux focusing magnetic gear assembly using ferrite magnets or the like. The present invention also relates generally to a flux focusing magnetic gear assembly using ferrite magnets or the like that incorporates an outer stator assembly that converts a variable input to a constant output. The present invention further relates generally to an axially aligned flux focusing magnetic gear assembly using ferrite magnets or the like. The improved flux focusing magnetic gear assemblies of the present invention find applicability in traction, wind, and ocean power generation, among other applications.

1. A flux focusing magnetic gear assembly, comprising:
an inner rotor comprising a plurality of concentrically disposed inner magnets separated by a plurality of concentrically disposed inner interstitial members, wherein the magnetic fields within the plurality of inner magnets are magnetized azimuthally through their thicknesses such that their opposite poles are at their opposite major planar faces; a middle rotor disposed about the inner rotor and comprising a plurality of concentrically disposed poles separated by one of a plurality of concentrically disposed gaps and plurality of concentrically disposed middle interstitial members; and an outer rotor disposed about the middle rotor and comprising a plurality of concentrically disposed outer magnets separated by a plurality of concentrically disposed outer interstitial members, wherein the magnetic fields within the plurality of outer magnets are magnetized azimuthally through their thicknesses such that their opposite poles are at their opposite major planar faces.
