Embodiment

[0025] Below, refer to Figure 1-Figure 6 , the disc-shaped coaxial counter-rotating generator 1 of the embodiment of the present invention will be described in detail.

[0026] Such as figure 1 As shown, the disc-shaped coaxial counter-rotating generator 1 of the present embodiment has a disc-shaped shell body 11 as a whole, and is driven by a natural energy source, such as a windmill 101 that is rotated by wind force as described later. Driven to rotate to efficiently obtain power generation output.

[0027] Such as figure 2As shown, the disc-shaped coaxial counter-rotating generator 1 is provided with: a fixed annular shaft 2, for example, a belt for supporting a support pillar 102 constituting a windmill 101 described in detail later is installed in a through hole 3 in the center. The stepped pillar part 103, the fixed ring-shaped shaft 2 is fixed to the stepped pillar part 103; the hollow disc-shaped shell main body 11 has a disc-shaped upper shell 12 and a disc-shape...

Abstract

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.

Description

technical field [0001] The present invention relates to a disk-shaped coaxial counter-rotating generator and a wind power generator using the disc-shaped coaxial counter-rotating generator. Background technique [0002] As is well known, for example, in wind power generators that have received attention in recent years, wind turbines are rotated using wind power as a natural energy source, power is generated using the rotational force of the wind turbines by a generator, and power generated based on wind power as a natural energy source is obtained for each A load device supplies power. [0003] In such a wind power generation device, especially a wind power generation device using a vertical axis / vertical airfoil wind turbine, the structure is often as follows: the wind turbine is arranged on the upper part of the pillar, and the disk generator is coaxially arranged directly below the wind turbine. , the rotational force of the windmill is transmitted to the disc-shaped ge...
