Abstract

Le rotor (1) selon l'invention comprend une pluralité de pôles Nord (N) et pôles Sud (S) alternés et formés à partir d'une pluralité d'aimants permanents (3) présentant une section radiale polygonale et agencés dans des premiers évidements (4). Ces premiers évidements se prolongent axialement et sont répartis régulièrement entre une partie circonférentielle (5) et une partie centrale (6) de la masse magnétique (2) du rotor de manière à définir une pluralité de sections polaires (10) circonférentielles. Conformément à l'invention, la section radiale comporte une partie sensiblement rectangulaire (8) proche de la partie circonférentielle adjacente à une partie sensiblement trapézoïdale (7) proche de la partie centrale. Selon une autre caractéristique du rotor, un rapport R d'une première hauteur h de la partie trapézoïdale à une seconde hauteur H de la partie rectangulaire, dans une direction radiale, est prédéterminé de manière à rendre maximum le rendement de la machine électrique.
