Abstract

a. L'invention concerne un aimant en forme de segment pour machines électriques, comportant une surface polaire intérieure, de préférence cylindrique, tournée vers l'induit de la machine, et une surface extérieure s'appliquant sur une culasse de retour de flux, par laquelle l'aimant est collé à la culasse. b. Cet aimant est caractérisé en ce que des éléments écarteurs sont disposés entre la surface extérieure de l'aimant en forme de segment et la culasse de retour de flux. c. L'invention est applicable notamment aux petits moteurs électriques.
