摘要

The dynamo has a rotating disc (10) with a set of clamps, and a magnet (20), which is formed in ring shape. Two iron claw rings (30) are formed as round shaped metal discs, and a set of magnetic claws is bent inwardly at the inner edge. A winding set (40) is formed at the outer side of an insulating wheel disc by windings. An outer cover (60) is formed fixedly and covers the rotating disc in a form fit manner. The cover encases the magnets, rings, winding set and a bearing and gripped in the rings in a form-fit manner to prevent the rotation of the winding set.
