Rotor for magnet generator

Abstract

Abstract PURPOSE:To improve the reliability, productivity and generating performance of a magnet motor by alternately forming contacting parts and parts having gaps between magnets, intimately contacting the holder of a thin magnetic plate with the inner periphery of the magnet and disposing the contacting parts between the magnets substantially to the center of the magnetized poles. CONSTITUTION:Annular holders 3 of nonmagnetic metal such as aluminum alloy or the like are disposed at both sides of a magnet 4, a projection 31 is formed on the side faced with the magnet 4 of the holder 3, and a plurality of magnets are disposed therebetween. The size of the projection 31 is set so that one side of the circumferential end of the magnet 4 is intimately contacted. On the other hand, the opening end of a flywheel 2 is formed thinly, the magnet 4 and the holder 3 are interposed between extruders 21, and the magnet 4 is secured to the inner periphery of the flywheel 2. Further, a cylindrical holder 6 made of a magnetic material having elastic property protects the inner periphery of the magnet 4, and the magnet 4 is pressed to the inner periphery of the flywheel 2.
