Abstract (en)
[origin: WO9964127A1] According to the invention, a generator for generating an electric current is provided inside a wheel for inline skates. Said generator consists of a magnet carrier (6) with a number of magnets (5), a short circuit ring (14) and a rotor (R). According to the invention, a pole disk (15) is arranged between the rotor (R) and the magnet carrier (6) and has a defined position in relation to the magnet carrier (6). The pole disk (15) has a number of pole elements (16) corresponding to the number of magnets (5). The shape of each pole element (16) is approximately that of a segment of a circular ring. Each pole element (16) is situated in a defined position in relation to one of the magnets (5), in such a way that the area centre of the pole element (16) is aligned with that of the magnet (5). The generator is more efficient as a result, and this can be used to measure the generator differently so as to reduce its braking effect. The magnet carrier (6) advantageously has a second defined position in relation to the pole disk (15), in which the area centres of the magnets (5) are situated exactly between two area centres of adjacent pole elements (16). The generator does not supply a current in the second position, and has no braking effect.
