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.
