A rotary direct current electric motor in which rotor and stator members are each configured as annular rings, concentric with respect to each other, about an axis of rotation. Either of the rotor or stator members is formed of groups of electromagnet pole pairs, the groups substantially equidistantly distributed along the angular extent of the annular ring, each of the groups comprising magnetic material magnetically isolated and separated from the other groups. The other member comprises a plurality of permanent magnet poles substantially equidistantly distributed with alternating magnetic polarity along the angular extent of the radial air gap formed between the members, the permanent magnet poles having a discontinuous magnetic return path, thereby dividing the member into magnetically isolated groups of permanent magnet poles.
Moteur électrique rotatif à courant continu dans lequel des éléments rotor et stator sont chacun configurés sous forme de structure annulaire et sont concentriques l'un par rapport à l'autre autour d'un axe de rotation. L'élément stator ou l'élément rotor est constitué de groupes de paires polaires d'électroaimants, lesdits groupes étant répartis de manière équidistante sur l'extension angulaire de la structure annulaire. Chacun des groupes comporte de la matière magnétique magnétiquement isolée et séparée des autres groupes. L'autre élément comporte une pluralité de pôles d'aimants permanents répartis de manière essentiellement équidistante et selon une polarité magnétique alternée sur l'extension angulaire de l'entrefer radial formé entre les éléments, les pôles d'aimants permanents ayant un trajet de retour magnétique discontinu, ce qui divise l'élément en groupes magnétiquement isolés de pôles d'aimants permanents.
