Abstract

Cette invention se rapporte à un moteur avec structure à deux rotors, lesquels sont placés sur l'arbre principal. Un stator cylindrique est fixé au logement du moteur et les deux rotors sont fixés sur le même arbre tournant dans le logement du moteur. Les deux rotors sont séparés l'un de l'autre par le stator qui est placé entre les rotors et un matériau magnétique est prévu sur la surface opposée des rotors. Dès lors que cette invention prévoit une structure à deux rotors, aucun couple de décrochage magnétique dans le champ magnétique des rotors n'est appliqué au stator et il n'y a pas de perte d'énergie, dès lors qu'aucune énergie n'est nécessaire pour surpasser le couple de décrochage magnétique. Ainsi, ce moteur se caractérise par des pertes d'énergie moindres pour l'activation, une charge d'activation plus grande, moins de perte sans charge et une plus grande puissance de sortie. Cette invention permet par conséquent d'économiser de l'énergie et d'accroître le rendement. Elle peut être utilisée pour des moteurs CA asynchrones, des moteurs CA synchrones, des moteurs CC sans balai électrique et des générateurs CA synchrones.
