ABSTRACT:
The present invention discloses a same polarity induction generator comprising a casing, a stator composed of a plurality of magnetic poles spaced away at a predetermined mechanical angle, a rotary shaft, a rotor mounted on said rotary shaft and composed of two pairs of ferrite magnets each pair having one polarity located outwardly of a circumference of the rotor and the other polarity located inwardly of the circumference, the respective pairs being arranged so as to have different polarities on the outer circumference of the rotor, magnetic cores fixedly mounted on the casing, and coil wirings each wound around said respective magnetic cores so as to intersect magnetic fluxes formed among said ferrite magnets. The stator may be composed of two magnets fixedly mounted on said casing and located on both ends of said rotary shaft, each magnet including quartered, arched sub-magnets, the sub-magnets having magnetic poles of the same polarities located on an outer circumference of the stator which polarities are different from those of said ferrite magnets. The rotor may be located at the center of said casing and operatively connected to said rotary shaft, the rotor being configured with vane members located at both ends of the rotary shaft through a cylindrical member disposed therebetween and being made rotatable interiorly of said stator segmented sub-magnets.
