Abstract:
1. A directed flux motor, comprising: permanent disc magnet; a first ferrous member non-rotatably fixed to said permanent disc magnet; a second ferrous member non-rotatably fixed to said permanent disc magnet; a non-ferromagnetic filler interposed between said first and second ferrous members, said filler providing an electrically isolation of said said first and second ferrous members; said first and second ferrous members defining first and second outer ring members provided with internal stator teeth, said stator teeth being wound with wire to define electromagnets; first and second inner rotating ring members circumscribed respectively by said first and second outer ring members, said first and second inner rotating ring members provided with rotor teeth facing said stator teeth; first and second grounded sun members respectively circumscribed by said first and second inner rotating ring members; a first plurality of planet gears interposed between said first inner rotating ring member and said first grounded sun member, and a second plurality of planet gears interposed between said second inner rotating ring member and said second grounded sun member, said first and second plurality of planet gears having teeth that mesh with corresponding teeth on said inner rotating ring members and said grounded sun members; a first output put shaft driven by said first plurality of planet gears, a second output shaft drive by said second plurality of planet gears, wherein a first flux path passes from said permanent magnet through said first ferrous member to said first inner rotating ring member through said first plurality of planet gears then through said first grounded sun member and back to said permanent magnet, said first flux path causing rotation of said first inner rotating ring member due to an attraction between said stator and said rotor teeth, and wherein rotation of said first inner rotating ring member causes rotation of said first output drive shaft through rotation of said second plurality of planet gears.
