Title (EN) AN ELECTRICAL MACHINE WITH A STATOR HAVING MULTIPLE SECTIONS WINDING COIL AND SWITCH COMBINATIONS
(FR) MACHINE ÉLECTRIQUE POURVUE D'UN STATOR À SECTIONS D'ENROULEMENT MULTIPLES ET À COMBINAISONS DE COMMUTATEURS
Abstract:
(EN) The present invention relates to an electrical machine for attaining varying torque at different speeds in vehicles by using switch combinations. The electrical machine comprises a coil with multiple sections C1, C2, C3, C4, C5, C6 connected such that all sections are in a series configuration to increase the Kt and some of the sections C1, C2, C3, C4, C5, C6 are connected in parallel to reduce the Ke. This increases the no-load speed during the motoring mode and reduces the voltage generated by the machine during the generation mode, by using switch arrangements. When the sections C1, C2, C3, C4, C5, C6 are connected in parallel, it reduces the resistance of each phase thereby reducing the copper losses and thus improves the efficiency of the machine. The applications are in integrated starter generator (ISG) system of any vehicles to provide high starting torque and to generate less voltage at high rpm. Also, can be used in any motor to provide torque to the vehicle at higher speeds.
(FR) La présente invention concerne une machine électrique permettant d'obtenir un couple variable à différentes vitesses dans des véhicules en faisant appel à des combinaisons de commutateurs. La machine électrique comprend une bobine à sections multiples (C1, C2, C3, C4, C5, C6) qui sont connectées de façon à être toutes dans une configuration en série afin d'augmenter le Kt, et certaines sections parmi les multiples sections (C1, C2, C3, C4, C5, C6) sont connectés en parallèle afin de réduire le Ke. Ainsi, en faisant appel à des agencements de commutateurs, la vitesse à vide augmente pendant le mode d'entraînement et la tension générée par la machine pendant le mode de génération diminue. Quand les sections (C1, C2, C3, C4, C5, C6) sont connectées en parallèle, la résistance de chaque phase est réduite, ce qui permet de réduire les pertes de cuivre et d'améliorer l'efficacité de la machine. L'invention peut être appliquée dans un système de générateur-démarreur intégré (ISG) de n'importe quel véhicule afin de fournir un couple de démarrage élevé et générer moins de tension à un tr/min élevé. En outre, l'invention peut être destinée à n'importe quel moteur afin de fournir un couple au véhicule à des vitesses plus élevées.
