Claim:
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; wherein the middle rotor comprises the plurality of concentrically disposed poles separated by and interlocked with the plurality of concentrically disposed middle interstitial members.
