Abstract
Description
Die Erfindung betrifft eine elektrische
Maschine, insbesondere Startergenerator, die sowohl motorisch als
auch generatorisch betreibbar ist. Eine solche elektrische Maschine
ist aus der japanischen Offenlegungsschrift
Vorteile der ErfindungAdvantages of invention
Die erfindungsgemäße elektrische Maschine mit den Merkmalen des Hauptanspruchs hat den Vorteil, dass durch das Tragen des Signalgebers durch einen Lüfter kein zusätzlicher Bauraum außerhalb des eigentlichen elektrische Maschine erforderlich ist. Das Signalgeberrad kann innerhalb der elektrischen Maschine gehalten werden.The electrical machine according to the invention with the features of the main claim has the advantage that No additional wear of the signal generator by a fan Installation space outside the actual electrical machine is required. The signaling wheel can be kept inside the electrical machine.
Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen der elektrischen Maschine nach dem Hauptanspruch möglich.By the measures listed in the subclaims are advantageous developments of the electrical machine according to the main claim possible.
Besonders einfach und kostengünstig ist es, wenn die Lüftertragscheibe eine Signalgeberkontur trägt.Is particularly simple and inexpensive it when the fan support disc carries a signal generator contour.
Am einfachsten ist die Verbindung zwischen Lüftertragscheibe und Signalgeberkontur ausgebildet, wenn die Signalgeberkontur beispielsweise als Verzahnung in die Lüftertragscheibe integriert ist, beispielsweise durch Ausstanzen, so dass Zähne am Außenrand der Lüftertragscheibe verbleiben.The easiest is the connection between fan support disk and signal generator contour, if the signal generator contour, for example as a toothing in the fan support disk is integrated, for example by punching out, so that teeth on the outer edge the fan support disc remain.
Eine weitere Möglichkeit, die Signalgeberkontur über die Lüftertragscheibe zu halten bzw. zu tragen besteht darin, die Signalgeberkontur zumindest mittelbar über einen Lüfter an der Lüftertragscheibe zu befestigen. Eine derartige Ausbildung hat den Vorteil, dass die Signalgeberkontur dadurch näher zu einer Außenseite der elektrischen Maschine angeordnet ist, und einerseits elektromagnetische Störungen auf das Sensorsignal durch die größere Entfernung zum Läufer bzw. Rotor verringert werden und andererseits die Sensorbaugruppe kleiner gestaltet werden kann.Another way to control the signal generator contour Fan support disk to hold or to carry is at least the signal generator contour indirectly via a fan on the fan support disk to fix. Such training has the advantage that the This means that the signal generator contour is closer to an outside the electrical machine is arranged, and on the one hand electromagnetic interference the sensor signal by the greater distance to the runner or rotor are reduced and on the other hand the sensor assembly can be made smaller.
In einer weiteren Ausgestaltung ist vorgesehen, dass die Signalgeberkontur Teil einer Deckscheibe ist, die die Luftführung des Lüfters zusätzlich verbessert.In a further embodiment provided that the signal generator contour is part of a cover plate, the air duct of the fan additionally improved.
Des Weiteren ist vorgesehen, dass die Lüftertragscheibe auf der Seite der elektrischen Maschine angeordnet ist, auf der die Kontakte zur Bestromung des Rotors angeordnet sind. Dies ermöglicht eine günstige Anordnung von Sensorleitungen im Bezug zur elektrischen Maschine. Die Sensorleitungen können somit sehr effektiv mit Anschlüssen für einen erforderlichen Wechselrichter zusammengefasst werden.It is also provided that the fan support disk is arranged on the side of the electrical machine on which the contacts for energizing the rotor are arranged. This enables one favorable Arrangement of sensor lines in relation to the electrical machine. The sensor lines can therefore very effective with connections for one required inverters can be summarized.
In einer weiteren Ausgestaltung ist vorgesehen, dass das Lüftertragscheibe aus einem austenitischen Stoff gefertigt ist, um sicherzustellen, dass die Sensorsignale keinen Störungen durch magnetischen Streufluss unterworfen sind.In a further embodiment provided that the fan support washer is made from an austenitic fabric to ensure that the sensor signals have no interference are subject to magnetic stray flux.
In den Zeichnungen sind Ausführungsbeispiele der erfindungsgemäßen elektrischen Maschine sowie verschiedene Ausführungsbeispiele für mögliche Ausführungsformen eines Signalgebers im Zusammenhang mit einem Lüfter dargestellt.Exemplary embodiments are shown in the drawings the electrical according to the invention Machine as well as various embodiments for possible embodiments of a signal generator in connection with a fan.
