Abstract:
1. A magnetoelectric generator comprising: a bowl-shaped flywheel having a cylindrical portion and a bottom portion; a plurality of permanent magnets fixed to an inner peripheral wall surface of said cylindrical portion so as to be arranged circumferentially; a resin material filled between adjacent pairs of said permanent magnets, said resin material fixing said permanent magnets integrally to said flywheel; a stator core disposed radially inside said flywheel such that an outer peripheral surface of said stator core faces said permanent magnets; and a generating coil configured by winding a conducting wire onto said stator core, said magnetoelectric generator generating electric power by electromagnetic induction between said permanent magnets and said generating coil due to rotation of said flywheel, wherein: a plurality of press-worked protrusions, which forcibly increase roundness of said flywheel, are formed by press working on said bottom portion of said flywheel.
