<p>A cycle wheel hub (2) having a DC generator arranged in it has a hub spindle (5) which is attached to frame parts (F) of the cycle and runs between a first end and a second end, as well as a first coil arrangement (7) which is supported on the hub spindle (5) and around which a wire (9) is wound, coaxially with respect to the hub spindle (5). In addition, a large number of magnets (8; 8a) are arranged radially outside the coil arrangement (7) such that they can be rotated relative to said coil arrangement (7), the magnets (8; 8a) having magnetic poles which are aligned radially with respect to the coil arrangement (7). This cycle wheel hub (2) additionally has a second coil arrangement which is supported on the hub spindle (5) alongside the first coil arrangement and around which a wire (9) is wound, coaxially with respect to the hub spindle (5). <IMAGE></p> |
