DISC-TYPE COAXIAL COUNTER-ROTATION GENERATOR AND WIND POWER GENERATION DEVICE USING DISC-TYPE COAXIAL COUNTER-ROTATION GENERATOR

WIPO Patent Application WO/2012/029168

A1

A disc-type coaxial counter-rotation generator (1) of the present invention comprises: a fixed annular shaft (2); a disc-shaped housing body (11) rotatably supported by the fixed annular shaft (2); disc-shaped flux interlinking magnets (21, 22) attached to the inside of the housing body (11); a disc-shaped coil body (31) disposed in the housing body (11) between the flux interlinking magnets (21, 22), in a state where a coil section (32) of the coil body (31) faces the flux interlinking magnets (21, 22) without making contact therewith and a center portion of the coil body (31) is rotatably attached to the fixed annular shaft (2); counter-rotation magnets (41) provided protruding from the outer periphery of the fixed annular shaft (2); a disc-shaped driving magnet (51) attached in a position facing the counter-rotation magnets (41) without making contact therewith; and a disc-shaped driven magnet (61) attached in a position facing the coil body (31) without making contact with the counter-rotation magnets (41). Thus, the disc-type coaxial counter-rotation generator can obtain high power generation output with less mechanical loss, less noise, and improved maintenance properties.
