Patent ID: 7786646

Claim:
A magnetic force rotation device comprising: a rotor including a plurality of magnetic elements containing permanent magnet arranged along a circumferential direction about a revolving shaft to form a rotor wheel-shaped ring, with each said magnetic element having respectively two magnetic poles; anda stator including a plurality of magnetically isolated electromagnetic members coaxially arranged around said revolving shaft to form a stator wheel-shaped ring, each said electromagnetic member having twin poles,wherein said stator wheel-shaped ring at least partly surrounded by said rotor wheel-shaped ring is such that each pole of said twin poles of said electromagnetic members of said stator corresponds to one magnetic pole of said two magnetic poles of said magnetic elements of said rotor respectively,wherein two axial component air-gaps are defined between said stator and said rotor, andwherein one of said poles of said electromagnetic members and said corresponding magnetic pole of said two magnetic poles of said magnetic elements define said an axial component air-gap and two radial component air-gaps therebetween.
