Abstract

La présente invention porte sur une génératrice bidirectionnelle multiphase sans noyau et qui peut éviter un phénomène en dents de scie qui apparaît pendant la rotation d'un rotor correspondant à un stator qui est formé d'un empilement de tôles d'acier au silicium, et qui accroît la production d'électricité par rotation du rotor et du stator dans des directions inverses l'une de l'autre et, en même temps, par réalisation d'une construction de stator à étage multiple pour augmenter une dose d'émail. C'est-à-dire que l'invention porte sur une génératrice bidirectionnelle multiphase sans noyau dans laquelle un faisceau de bobinage formé par bobinage d'un fil émaillé est monté dans une encoche d'un boîtier de bobine entre des aimants permanents qui sont agencés de façon à avoir des pôles opposés face à face à un écartement prédéterminé, en liaison mutuelle de cette façon avec des lignes de flux issues des aimants permanents, et le stator bobiné avec un fil émaillé tourne dans le sens inverse de la rotation du rotor fixé aux aimants permanents de manière à induire une haute tension de génération, même à une faible vitesse de rotation. Pour cela, des éoliennes ayant des pales tournant dans des sens inverses sont reliées respectivement au rotor et au stator. Le stator bobiné avec un fil émaillé peut être fabriqué dans un procédé à phase multiple (par exemple à 2 phases) le long d'un cercle concentrique, de sorte que la génération d'électricité peut être augmentée.
