Abstract

L'invention concerne un générateur d'électricité de démarrage comprenant quatre bobines triphasées (1a-1d) et fonctionnant comme démarreur et comme générateur d'électricité. L'enroulement de la bobine (1d) générant l'électricité de démarrage est utilisé lorsque le générateur d'électricité de démarrage fonctionne comme générateur d'électricité et comme moteur, et disposé entre les bobines (1a-1c) destinées à être utilisées uniquement lorsqu'une machine dynamoélectrique fonctionne comme moteur. Pour générer de l'électricité, seule la bobine (1d) générant l'électricité de démarrage est utilisée. A cet instant, l'énergie électrique produite par l'enroulement (1d) générant l'énergie de démarrage s'annule en raison de la disposition des enroulements, de façon que les balances magnétiques soient égalisées durant la production d'énergie électrique.
