Abstract

La présente invention concerne un dispositif de prise de courant pour machines électriques à collecteur. La surface active du collecteur de courant comporte des micro-aspérités réalisées sous la forme de canaux 4 orientés, par rapport à la génératrice de la surface active, sous un angle alpha dont la valeur dépend du rapport entre le diamètre du collecteur de courant et la période de succession des canaux, la relation entre la largeur des canaux et la période de leur succession étant de 0,4 à 0,9. Applications : micromoteurs à courant continu.The present invention relates to a socket device for electrical machines with a collector. The active surface of the current collector comprises micro-asperities made in the form of channels 4 oriented, with respect to the generatrix of the active surface, at an alpha angle whose value depends on the ratio between the diameter of the current collector and the period of succession of the channels, the relation between the width of the channels and the period of their succession being from 0.4 to 0.9. Applications: direct current micromotors.
