Abstract:
An axial gap motor including:a radially extending stator supporting a radially extending electric conducting coil;a shaft extending essentially perpendicular to said radially extending stator and said radially extending electric conducting coil;a radially extending rotor, fixed to said shaft and rotatable therewith, adjacent to said radially extending stator and said radially extending electric conducting coil supported by said stator;magnet support means on said radially extending rotor movable radially inwardly and radially outwardly adjacent to said radially extending electric conducting coil;magnets held by said magnet support means such that a magnetic flux of said magnets can interact with a magnetic flux of said electric conducting coils to vary back emf generated within said electric conducting coil as said magnet support means moves radially inwardly and radially outwardly;said magnets at a radial inward at rest position are located adjacent to said radially extending electric conducting coil such that said flux of said magnets essentially overlaps said flux of said radially extending electric conducting coil;said magnets moved radially outward from said radial inward at rest position, results in only a partial radial overlap of said flux of said magnets and said flux of said radially extending electric conducting coil.
