A rotary electric motor comprises a rotor having a plurality of permanent magnet elements disposed in an annular ring configuration about an axis of rotation, the magnet elements successively alternating in magnetic polarity along an inner annular surface, and a stator spaced form the rotor by a radial air gap. The stator includes a plurality of magnetic core segments having respective coils wound thereon to form stator windings, the core segments separated from direct contact with each other and disposed along the radial air gap. Each stator segment comprises a pair of poles aligned with each other in a direction parallel to the axis of rotation. Thus the stator comprises a first set of stator poles in radial alignment and an axially displaced second set of stator poles in radial alignment.
Un moteur électrique rotatif comprend un rotor possédant plusieurs éléments magnétiques permanents disposés annulaires par rapport à un axe de rotation, les éléments magnétiques étant alternés successivement par rapport à la polarité magnétique sur une surface interne annulaire, et un stator séparé du rotor par un entrefer radial. Le stator comprend plusieurs segments de noyau magnétique possédant des bobines respectives enroulées sur ceux-ci de manière à former des enroulements de stator, les segments de noyau étant séparés, de manière à ne pas être en contact direct entre eux, et disposés le long de l'entrefer radial. Chaque segment de stator comprend une paire de pôles alignés l'un sur l'autre dans une direction parallèle à l'axe de rotation. Le stator comprend ainsi un premier ensemble de pôles de stator alignés radialement et un ensemble axialement déplacé de pôles de stator alignés radialement.
