Description

A generator, built in a wheel nave, is disclosed. The wheel nave and a casing (2), enclosing the generator rotate around a fixed wheel axis (1). The generator comprises a coil (14) concentric with the wheel axis and fixed to wheel axis (1). The generator is especially characterised in that magnets are provided, concentric with the coil (14) turning a first group with alternating N- and S-magnet poles (21, 22) to a first plane, and a second group with alternating N- and S-magnet poles to an opposite second plane. A first and a second pole changer (12, 13) are provided to rotate in relationship to the wheel axis (1), whereas during the rotation one of the pole changers (12) passes relatively close to the first group of magnet poles and the second pole changer (13) passes relatively close to the second group of magnet poles.

Générateur monté dans un essieu de roue. L'essieu de roue et un boîtier (2) renfermant le générateur tournent autour d'un axe (1) fixe de roue. Ce générateur comporte une bobine (14) concentrique à l'axe de la roue et fixée à cet axe (1). Ce générateur est en particulier caractérisé en ce que des aimants sont placés concentriques avec la bobine (14), un premier groupe d'aimants à pôles (21, 22) alternés N et S tournant dans un premier plan et un second groupe d'aimants à pôles N et S alternés tournant dans un second plan opposé au premier. Des premier et second commutateurs de polarité (12, 13) sont conçus pour tourner avec l'axe (1) de la roue et pendant la rotation, un (12) des commutateurs de polarité passe relativement près du premier groupe de pôles magnétiques et le second commutateur de polarité (13) passe relativement près du second groupe de pôles magnétiques.
