A permanent magnet D.C. motor (90) includes a stator assembly (112) with a plurality of upstanding discrete spaced-apart core components (116) formed in a circular locus generally parallel with the motor axis. Each core component includes a relatively lengthy winding association region and extending therefrom a pole piece region (128) providing a flux interaction surface. A field winding (122) mounted upon a bobbin is positioned over a core component at the winding association region. A permanent magnet component (130) is carried by a rotor (100) such that its interaction surface is adjacent to that at the pole piece region (128), and is spaced therefrom to define a flux working air gap (132).
L'invention concerne un moteur à courant continu à aimants permanents (90) qui comprend un ensemble stator (112) ayant plusieurs composantes noyau discrètes (116) en saillie et écartées les unes des autres, formant un site circulaire parallèle à l'axe du moteur. Chaque composante noyau (116) comprend une zone d'association de bobinage relativement longue et, partant d'elle, une zone d'élément pôle (128) fournissant une surface d'interaction de flux. Un inducteur (122) monté sur une bobine est placé au-dessus d'une composante noyau dans la zone d'association de bobinage. Une composante aimants permanents (130) est portée par un rotor (100) de sorte que sa surface d'interaction est adjacente à celle dans la zone d'élément pôle (128) et est écartée d'elle de manière à définir un entrefer de travail de flux (132).
