Abstract

L'invention concerne un rotor qui comporte N pôles, N étant un nombre pair, et comprend un empilement (LS) de plaques (L) de matière magnétique, chacune de celles-ci comportant N secteurs (1-4) angulaires adjacents; une pluralité correspondante de cavités ou d'ouvertures (C) sont formés dans cet empilement, et des éléments magnétiques permanents (M) correspondants se déploient à l'intérieur desdites cavités ou ouvertures. Lesdits éléments sont magnétisés dans chaque secteur (1-4) dans la direction opposée à celle des secteurs adjacents, et sont formés à partir d'une matière magnétique moulée dans les ouvertures ou cavités (C) de l'empilement (LS) des plaques (L).
