Abstract

« Procédé d'optimisation d'un moteur électrique en vue d'une mesure de vitesse ou déplacement ou position, notamment dans un actionneur de freinage automobile » L'invention propose un moteur électrique périodique, notamment rotatif, comprenant des moyens de commutation électrique alimentant d pôles chacun seulement une partie de période. Ils absorbent le courant selon un profil temporel, couvrant seulement une partie de ladite période. Au moins un pôle repère est agencé ou commuté de façon à absorber un courant selon un profil repère(p'3,p'10), différent du profil temporel des autres pôles pour une même tension d'alimentation; pour créer dans l'alimentation du moteur un signal avec des variations spécifiques liées à la commutation desdits pôles repères, permettant ainsi à une unité électronique de détecter ces pôles repères en mesurant l'intensité et/ou la tension d'alimentation pour y détecter ces variations. Un collecteur rotatif peut comporter un contact repère d'une géométrie différente. Un circuit de commutation ou de pôle peut prévoir un circuit pour créer un signal repère supplémentaire.
