Abstract

L'invention concerne l'utilisation d'un dispositif de démarrage pour moteurs à combustion interne, comprenant un moteur de démarrage (13) se présentant sous la forme d'un moteur électrique à courant continu présentant trois paires de pôles dans le stator (35), ainsi qu'un induit (37) pouvant être alimenté par l'intermédiaire d'un commutateur (52). Au moins deux paires de balais constituées respectivement d'un balai positif et d'un balai négatif reposent sur le commutateur (52) en vue de l'alimentation en courant, au moins une paire de balais étant réglée par rapport à une paire de pôles dans le stator (35) selon un angle de commutation mécanique (ßmech) supérieur à 8 degrés d'angle mécanique. Le dispositif de démarrage est caractérisé par le fait qu'il peut être utilisé dans un système de marche-arrêt.
