Abstract:
An electric power generator comprising:a stator including a plurality of stator members, each stator member including a coil and top and bottom elements separated by a gap, each of said top and bottom elements include a face having a shape;a rotor having a plurality of magnets, said rotor being rotatably mounted, such that said magnets pass within said gaps in said stator members when said rotor is rotated with respect to said stators, said magnets having a top surface and a bottom surface, wherein said top and bottom surfaces being shaped to substantially match said shape of said stator faces; andeach of said magnets overlapping said stator faces as said rotor rotates a distance, such that an area of overlap and non-overlap of each of said magnets changes non-linearly as the distance between each of said magnets and said stator faces changes linearly to thereby produce a non-linear magnetic field interaction between said magnets and stator members.
