Abstract

Selon la présente invention, un noyau de stator entourant la périphérie d'un rotor comprend : une section tubulaire ; et plusieurs sections dents de pôle magnétique disposées à intervalles dans la direction circonférentielle de la section tubulaire, chacune d'entre elles dépassant de la section tubulaire vers l'intérieur dans la direction du diamètre. Chaque section dent de pôle magnétique comporte une bobine de stator. Un isolateur bobine-noyau se trouve entre la bobine de stator et le noyau de stator afin d'assurer l'isolation entre la bobine de stator et le noyau de stator. Cet isolateur bobine-noyau présente une section de chevauchement de section tubulaire destinée à être chevauchée par la surface circonférentielle intérieure de la section tubulaire. Un isolateur inter-bobines se situe entre les bobines de stator afin d'assurer l'isolation entre ces bobines de stator. Une rainure d'insertion, qui s'ouvre vers l'intérieur dans la direction du diamètre du noyau de stator, est présente à l'emplacement de la section de chevauchement de section tubulaire dans la direction axiale du noyau de stator. Ledit isolateur inter-bobines est fixé sur le noyau de stator grâce à l'insertion de l'isolateur inter-bobines dans la rainure d'insertion par glissement d'une section d'insertion, qui constitue une partie de l'isolateur inter-bobines, dans le sens de la longueur de la rainure d'insertion.
