Abstract

L'invention concerne un moteur linéaire peu coûteux tel qu'il est facile de retirer une petite pièce magnétique attirée par un aimant permanent, et dont l'heure d'assemblage personne est réduite. Ledit moteur linéaire comprend des pôles magnétiques (3) composés d'aimants permanents (2) agencés de manière linéaire de sorte que les polarités de ces pôles sont alternées; un noyau d'induit possédant des dents et des fentes espacées des pôles magnétiques; et un enroulement d'induit composé d'une bobine et monté dans une fente dudit noyau d'induit. Les pôles magnétiques sont des aimants permanents (2a) en forme de parallélogramme pouvant constituer une unité magnétique permanente équivalente à plusieurs aimants permanents, et sont fabriqués par magnétisation multipôle d'une ébauche d'aimant permanent d'une seule pièce en forme de parallélogramme.
