A method of making a rotor (10) for a permanent magnet motor, said rotor comprising a rotor body (14) for emplacement of magnets (MS) thereon, the rotor body having a generally cylindrical shape with an interior surface and an exterior surface, which method comprises the steps of: (a) applying a plurality of magnets (MS) to a surface of the rotor body (14), the magnets held to the rotor body by magnetic force; (b) emplacing a shunt structure (30) ove r the plurality of magnets on said rotor body to inhibit inter - magnet action during application of further magnets adjacent said plurality of magnets, whereby each pole on said rotor may be constructed from a plurality of magnets with the same magnetic pole orientation on sa id rotor body.

La présente invention concerne un procédé de fabrication de rotor (10) pour moteur à aimant permanent, ledit rotor comprenant un corps de rotor (14) sur lequel placer des aimants (MS), le corps du rotor étant de forme généralement cylindrique et comportant une surface intérieure et une autre extérieure ; le procédé se compose des étapes suivantes : (a) application d'une pluralité d'aimants (MS) ) sur une surface de corps de rotor (14), les aimants étant retenus au corps du rotor par une force magnétique ; (b) placement d'une structure de dérivation (30) sur la pluralité d'aimants sur le corps du rotor pour empêcher l'action inter-aimant lors de l'application d'autres aimants adjacents à la pluralité d'aimants existants ; chaque pôle dudit rotor peut être construit d'une pluralité d'aimants ayant la même orientation de pôle magnétique sur ce corps de rotor.
