Abstract
A rotor of a magnetic generator has a plurality of permanent magnets (13) disposed on an inner surface of a peripheral wall (11a) of a bowl-shaped flywheel (11). The permanent magnets (13) are held in place by a magnet-holding cylinder (14) having plural outward protrusions (14c) formed in a radial direction at a first open end and an outward flange (14e ) formed on a second open end thereof. Resin (15) is provided to fill empty spaces of this assembly so that the magnets (13), the magnet-holding cylinder (14) and the flywheel (11) are made of an integral piece thereby.
Claims6
A rotor of a magnetic generator, comprising:
- a bowl-shaped flywheel having a disc-shaped bottom part and a cylindrical peripheral wall part of a first inside diameter;
- a plurality of magnets, disposed on an inner surface of said peripheral wall of said flywheel at intervals of a predetermined angle;
- a magnet-holding cylinder having an inner cylindrical surface of a predetermined second diameter smaller than said first inside diameter having an outward flange formed on a first open end and a plurality of outward protrusions circularly formed on a second open end at intervals of another predetermined angle, said plurality of magnets being respectively positioned thereby to be parallel to the axis of said magnet-holding cylinder;
- and
- a resin molded member, that fills in spaces formed between said flywheel, said magnets and said magnet-holding cylinder for making said flywheel, said magnets and said magnet-holding cylinder in one piece so as to leave an inside open space contiguous with said inner cylindrical surface.
