A switched reluctance motor includes a stator defining a plurality of radially-inwardly-extending poles and a rotor defining a plurality of radially-outwardly-extending poles. The poles of the stator and the rotor are respectively divided into at least two longitudinal sections, with each pole section featuring a different shape when viewed in radial cross-section. The shape of one rotor pole section is such as to subdivide the pole into three teeth, namely, a central tooth flanked on either side by a side tooth, further characterized in that the shape of the central and side teeth are symmetric relative to a radius bisecting the central tooth. In a preferred embodiment, the circumferential spacing between the central tooth and each side tooth of one rotor pole is less than the circumferential spacing between the opposed side teeth of adjacent rotor poles.
Moteur SRM composé d'un stator définissant un certain nombre de pôles rayonnant vers l'intérieur et d'un rotor définissant un certain nombre de pôles rayonnant vers l'extérieur. Les pôles du stator et du rotor sont respectivement divisés en au moins deux sections longitudinales, chacune présentant une forme différente en coupe transversale. Du point de vue de la forme, une section de pôle de rotor subdivise le pôle en trois dents, soit une dent centrale flanquée de deux dents latérales, les trois dents formant un ensemble symétrique de part et d'autre d'un rayon médian de la dent centrale. Dans une version préférée, l'espacement à la périphérie entre la dent centrale et les dents latérales d'un pôle de rotor est inférieur à celui qui sépare les dents latérales opposées des pôles de rotor adjacents.
