Dynamo light machine especially for bicycle

摘要

The light machine includes a fixed, ring shaped armature and a ring shaped stator. The stator is fastened to the wheel and rotates next to the armature. The armature and the stator each comprise a ring (1). An even number of preferably curved induction coils (2) wound alternately right and left are attached to the armature ring. The induction coils are connected in series by connector wires (3). One connection is interrupted at a point and the two resulting cable ends serve as terminals (4). Axially magnetised, preferably curved permanent magnets are fastened to the stator ring and are arranged such that opposite poles follow consecutively. The number of magnets is precisely the same as the number of induction coils on the armature. The entire generator can be attached to the cycle without great constructive changes.
