Description
Stand der TechnikState of technology
Die
Erfindung geht aus von einer elektrischen Maschine nach dem Oberbegriff
des Patentanspruchs 1 mit mehreren Wicklungssträngen. Aus der EP-B-917755 oder
der
Es ist außerdem ein Verfahren und eine Anordnung bekannt (EP-B-689054), mit deren Hilfe die Auswertung des analogen Signals des Kommutierungsstromes mit geringem Aufwand schaltungstechnischer und kostenmäßiger Art teilweise gelöst wird.It is also a method and an arrangement known (EP-B-689054), with the Help the evaluation of the analog signal of the commutation current with little effort circuitry and cost Art partially solved.
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße elektrische Maschine mit den kennzeichnenden Merkmalen des Patentanspruchs 1 hat den Vorteil, dass Fehlzählungen durch Synchronisationspulse korrigiert werden.The electrical according to the invention Machine with the characterizing features of patent claim 1 has the advantage of miscounting be corrected by synchronization pulses.
Hierzu weist die elektrische Maschine mehrere Wicklungsstränge auf, von denen mindestens ein Wicklungsstrang elektrisch unterschiedlich zu den anderen Wicklungssträngen ausgeführt ist.For this the electric machine has several winding phases, of which at least one winding strand electrically different to the other winding strands accomplished is.
Auf einfache Weise lässt sich dies erreichen, indem der Widerstand wenigstens eines Wicklungsstrangs anders als der von anderen Wicklungssträngen ausgeführt ist. Dies lässt sich am einfachsten bewerkstelligen, indem der ohmsche Widerstand wenigstens eines Wicklungsstrangs niedriger oder höher als der von anderen Wicklungssträngen ausgeführt ist. Die einfachste Umsetzung ist die, wenigstens ein Wicklungsstrang mit wenigstens einer Windung mehr oder weniger als andere Wicklungssträngen zu versehen.On easy way lets achieve this by the resistance of at least one winding strand unlike that of other winding strands. This is possible the easiest way to accomplish this, by the ohmic resistance at least a winding strand is made lower or higher than that of other winding strands. The simplest implementation is the, at least one winding strand with at least one turn more or less than other winding strands Mistake.
Weitere Vorteile und vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen und der Beschreibung.Further Advantages and advantageous developments emerge from the subclaims and the Description.
