POWER GENERATION DEVICE, ARMATURE STRUCTURE FOR POWER GENERATION DEVICE, AND METHOD FOR MANUFACTURING ARMATURE

摘要

A power generation device equipped with: two disk-shaped rotors that are fixed to a rotary shaft; a field system that has an even number of magnetic poles that are arranged on the same circumference, said magnetic poles comprising permanent. magnets that are fixed to the rotors in such a manner that the magnetization directions of the magnets are parallel to the axis of the rotary shaft with the directions being alternately arranged; and a stator that comprises coil substrates on which conductive patterns are formed so as to cross magnetic fluxes generated by the permanent magnets when the rotors rotate. Multiple conductive patterns corresponding to the number of phases are disposed in the stator, and electric power generated for each phase can be independently output.

1. A device for generating electric power, including:
a disc-shaped rotor fixed to a rotation shaft; a magnetic field including an even number of magnetic poles arranged on a common circumference, said magnetic poles comprising permanent magnets fixed to said rotor, being magnetized in a direction in parallel with an axis of said rotor, and being magnetized in alternate directions; coil substrates on which electrically conductive patterns are formed for each of phases so as to cross magnetic fluxes generated by said magnetic field when said rotor is in rotation, leading-wire substrates through each of which ends of said electrically conductive patterns of said coil substrates fbr each of phases are extracted outwardly for full phase, and a stator comprised of said coil substrates in a number equal to a number of said phases and a single substrate comprised of said leading-wire substrate, said coil substrates and said single substrate being stacked one on another, wherein each of said coil substrates is in the shape of a disc formed with a through hole through which said rotation shaft is fixed, each of said electrically conductive patterns is defined by a plurality of rows of gear-shaped patterns electrically connected in series to one another, each of said gear-shaped patterns including linear patterns extending radially of said rotation shaft and arcuate patterns extending circumferentially of said rotation shaft such that said linear patterns and said arcuate patterns are alternately arranged to thereby be in the shape of a gear having N teeth equal to a number of said poles, and said electrically conductive patterns of said coil substrates are formed such that electric power generated in each of phases can be output independently of one another.
