The invention relates to a device for generating electrical energy, in the form of a windmill. Said device comprises a rotor (20) with at least one winding (22), a stator (10) with at least one magnet (11); and at least one electrical consumer (23). The at least one electrical consumer is situated on the rotor and is connected to the at least one coil. It is therefore unnecessary to transmit power from the stator to the rotor to supply the consumer e.g. by means of sliding contacts, with the result that the running and starting resistance of the rotor is reduced. This is especially important for a windmill. Said consumers are preferably small lamps such as light- emitting diodes or similar, which light up as soon as the windmill begins to be turned by the wind. This creates attractive effects, especially when a number of differently coloured light-emitting diodes are used on the blades (21) of the windmill.
Dispositif, tel qu'une éolienne éclairée, à production d'énergie électrique, qui comporte un rotor (20) doté d'au moins une bobine (22), un stator (10) doté d'au moins un aimant (11) et au moins un dispositif de consommation électrique (23). Le dispositif de consommation électrique est disposé sur le rotor et connecté à la bobine au moins. Un transfert de courant pour alimenter le dispositif de consommation électrique du stator au rotor, par exemple à l'aide de contacts frottants, n'est donc pas nécessaire, une réduction de la résistance de démarrage et de rotation du rotor étant ainsi obtenue, ce qui est particulièrement important pour une éolienne. Les dispositifs de consommation d'énergie sont de préférence des petites lampes telles que des diodes électroluminescentes (DEL) ou analogues qui s'illuminent aussitôt que l'éolienne commence à tourner sous l'influence du vent. L'utilisation en particulier d'une pluralité de diodes de différentes couleurs sur les pales (21) de l'éolienne permet d'obtenir de jolis effets.
