ABSTRACT:
A bicycle dynamo with a rotary-current generator having a stator and a rotor which can be rotated relative to the stator. The stator or the rotor has radially extending pole fingers which are wound individually with one surrounding magnetic coil winding respectively. The ratio of the number of poles of the rotor to the number of poles of the stator is a non-integer value, and the ratio of the number of poles of the stator to the number of poles of the rotor is a non-integer value. This permits the implementation of a bicycle dynamo of a high efficiency even at a relatively low riding speed, which may be used, for example, to power bicycle lighting systems.
