Title:
POWER GENERATION DEVICE, ARMATURE STRUCTURE FOR POWER GENERATION DEVICE, AND METHOD FOR MANUFACTURING ARMATURE
Document Type and Number:
WIPO Patent Application WO/2015/111579
Kind Code:
A1
Abstract:
Provided are a power generation device, an armature structure for the power generation device, and a method for manufacturing the armature, such that a process of winding power-generating coils is unnecessary, a higher fill factor than with wires is achieved, and cogging does not occur. This power generation device is equipped with: two disk-shaped rotors (3, 4) that are fixed to a rotary shaft (1); a field system that has an even number of magnetic poles that are arranged on the same circumference, said magnetic poles comprising permanent magnets (9) that are fixed to the rotors (3, 4) in such a manner that the magnetization directions of the magnets are parallel to the axis of the rotary shaft (1) with the directions being alternately arranged; and a stator (2) that comprises coil substrates on which conductive patterns are formed so as to cross magnetic fluxes generated by the permanent magnets (9) when the rotors (3, 4) rotate. Multiple conductive patterns corresponding to the number of phases are disposed in the stator (2), and electric power generated for each phase can be independently output. A power-generating coil of the armature structure for the power generation device comprises a conductive pattern (Pu1 (Pv1, Pw1)) that is formed on a surface of a coil substrate (10) that is made of an insulating material, and multiple conductive patterns (Pu1 (Pv1, Pw1)) corresponding to the number of phases are disposed.
