Electric generator for bicycle or individual wheel with rotor at rotatable wheel - equipped with permanent magnets and stator formed by coil system for receiving induced voltage is fixed on wheel spindle and generator can be used as servo motor

摘要

An accumulator (3, fig 1) is provided for storing the electrical power generated by the travel movement. An electronic circuit arrangement on a PCB(23) is switchable, such that selectively the lighting and/or the generator driven as a motor (2) are supplied from the accumulator (3). Magnetic field dependent semiconductors are arranged with predetermined angular spacing are arranged between the windings of the stator (20), which with motor operation working in conjunction with the electronic circuit arrangement, ensure that always at least one stator winding is excited. ADVANTAGE - Electrical generator can be used as motor for drive assistance without mechanical contact. Illumination maintained at standstill also for short journeys.
