Abstract

Machine électrique tournante permettant de réduire de façon notable le couple crénelé dû aux dents ainsi que le couple ondulant. La machine comprend un aimant permanent qui forme des pôles nord et sud placés l'un après l'autre, et un noyau d'induit qui est placé coaxialement à l'aimant permanent et comporte plusieurs pôles saillants en face de cet aimant Des enroulements polyphasés sont bobinés sur la base des pôles saillants. Grâce à la présence d'une partie dentelée sur la face principale des pôles saillants en face de l'aimant permanent, on peut réduire de façon notable le couple crénelé; de plus en prévoyant des pôles saillants auxiliaires, le couple ondulant peut également être réduit. Application aux machines électriques tournantes.
