Abstract
(DE)
Es ist schon eine Maschinenkomponente einer elektrischen Maschine bekannt, umfassend Zähne, an denen jeweils ein Erregermodul vorgesehen ist, das jeweils Eingangsanschlüsse zur Verbindung mit einer Gleichspannungsquelle oder mit einer Wechselspannungsquelle, jeweils zumindest eine Leiterbahn zur Bildung einer Einzelzahnwicklung und zumindest einen Halbleiterschalter zur Erzeugung einer an der zumindest einen Leiterbahn anliegenden Phasenwechselspannung aufweist. Die Leistung einer die erfindungsgemäße Maschinenkomponente aufweisenden elektrischen Maschine kann während des Betriebs der elektrischen Maschine einfach eingestellt oder verstellt werden, so dass eine einfache Drehzahl- bzw. Drehmomentregelung ermöglicht wird. Erfindungsgemäß ist vorgesehen, dass die auf dem jeweiligen Erregermodul (3) ausgebildete Einzelzahnwicklung (5) jeweils aus mehreren elektrisch parallel geschalteten Teilspulen (10) gebildet ist und dass auf dem jeweiligen Erregermodul (3) pro Teilspule (10) mindestens ein Halbleiterschalter (6) zur Erzeugung einer an der jeweiligen Teilspule (10) anliegenden Phasenwechselspannung vorgesehen ist.

A machine component of an electric machine is already known, comprising teeth on which a respective exciter module is provided, which has respective input connections for connecting to a DC voltage source or to an AC voltage source, a respective at least one conductor path for forming a single tooth winding, and at least one semiconductor switch for generating a phase AC voltage applied at the at least one conductor path. The power of an electric machine having the machine component according to the invention can be simply set or adjusted during operation of the electric machine, such that a simple control of rotational speed or torque is permitted. According to the invention, the single tooth winding (5) formed on the respective exciter module (3) is formed of multiple sub-coils (10) electrically connected in parallel, and at least one semiconductor switch (6) is provided per sub-coil (10) on the respective exciter module (3) for generating a phase AC voltage applied at the respective sub-coil (10).

La présente invention concerne un composant de machine d'une machine électrique déjà connu, comprenant des dents sur lesquelles est disposé un module d'excitation respectif, qui présente des connexions d'entrée respective à une source de tension continue ou à une source de tension alternative, un trajet de conducteur respectif pour former un enroulement de dent individuel, et au moins un commutateur à semi-conducteur pour générer une tension alternative de phase appliquée au niveau dudit trajet de conducteur. La puissance d'une machine électrique ayant le composant de machine selon l'invention peut être réglée ou ajustée de manière simple pendant le fonctionnement de la machine électrique, de telle sorte qu'une commande simple de vitesse de rotation ou de couple est permise. Selon l'invention, l'enroulement de dent individuel (5) formé sur le module d'excitation respectif (3) est constitué de multiples sous-bobines (10) électriquement connectées en parallèle, et au moins un commutateur à semi-conducteur (6) par sous-bobine (10) est disposé sur le module d'excitation respectif (3) pour générer une tension alternative de phase appliquée à la sous-bobine respective (10).
