Magnet-type power generator and method of manufacturing the same
A magnet-type power generator includes a rotor having a bowl-shaped flywheel and plural magnets disposed on an inner circumferential surface of the flywheel so as to be spaced at a predetermined interval, and a stator having plural cores facing the magnets and each having a coil wound therearound. The magnets include a bonded magnet integrally molded with the flywheel.
1. A magnet-type power generator comprising:
a rotor having a bowl-shaped flywheel and a plurality of magnets disposed on an inner circumferential surface of the flywheel so as to be spaced at a predetermined interval; and
a stator having a plurality of cores facing the magnets, each having a coil wound therearound,
wherein the plurality of magnets comprises a plurality of bonded magnets integrally molded with the flywheel on the inner circumference surface and a bottom surface of the flywheel,
wherein the bonded magnets are molded so as to be coupled to each other by coupling parts formed on a bottom side of the flywheel.
2. A method of manufacturing a magnet-type power generator comprising a rotor having a bowl-shaped flywheel and a plurality of magnets disposed on an inner circumferential surface of the flywheel so as to be spaced at a predetermined interval, and a stator having a plurality of cores facing the magnets and each having a coil wound therearound, the method comprising:
using a bonded magnet as at least one of the plurality of magnets; and
injection molding the bonded magnet integrally with the flywheel on the inner circumference surface and a bottom surface of the flywheel.
3. The method of manufacturing a magnet-type power generator according to claim 2 , further comprising:
after injection molding the bonded magnet, plating the bonded magnet simultaneously with the flywheel.
