APPARATUS FOR GENERATING ELECTRICITY IN THIN DISK SHAPE

摘要

An apparatus for generating electricity in a thin disk shape is provided to improve a generating efficiency by using a frame as a core since a coil is wound to the frame and to activate with a low rotation force since only a permanent magnet is rotated with the frame fixed. An apparatus for generating electricity in a thin disk shape includes a frame(100), a plurality of permanent magnets(200), a plurality of coils(300), a plurality driven gears(400), and a plurality of driving gears(500). The frame has a ring shape. A plurality of through holes(110) are arranged in a circumferential direction at a predetermined interval. The permanent magnets are rotatably installed in the through holes of the frame on an axis parallel to a center axis of the frame. The coils are wound by using as a core a portion between a predetermined pair of through holes adjacent to each other among the through holes of the frame. The driven gears are fixed to the permanent magnets and rotate together with the permanent magnets. The driving gears are in contact with the corresponding driven gears.
