Abstract

L'invention se rapporte au domaine de l'électrotechnique et concerne notamment des générateurs électriques à faible vitesse de rotation, et peut être utilisée dans des installations éoliennes. Le générateur magnéto-électrique comprend un rotor qui est équipé d'aimants permanents, et un stator qui comprend deux plaques parallèles entre lesquelles sont disposés des enroulements annulaires. Les enroulements sont réalisés sous forme de trapèzes isocèles dont les côtés sont disposés radialement par rapport à l'axe de rotation du rotor. Les zones des enroulements dans les bases des trapèzes sont convexes en suivant un arc de cercle. Le rotor est constitué de disques parallèles montés sur un arbre et portant chacun sur leurs surfaces se faisant face des rangées annulaires d'aimants permanents dont la polarité alterne pour chaque rangée. Les pôles des aimants permanents d'une rangée faisant face aux pôles opposés des aimants permanents de l'autre rangée. Les enroulements d'extrémités sont enfichés les uns dans les autres, la distance 1 entre les zones d'enroulements annulaires dans la base des trapèzes dépasse la largeur b de la rangée annulaire d'aimants permanents. Entre les enroulements annulaires on a placé un enroulement plat supplémentaire sous la forme d'un trapèze isocèle dont les côtés latéraux sont disposés dans un même plan entre les côtés latéraux des autres enroulements annulaires.
