Abstract
Description
Die Erfindung betrifft einen Elektroantrieb, insbesondere Elektroachse, mit mindestens einer elektrischen Maschine, die eine Mehrzahl von Spulen in einem Maschinengehäuse aufweist, und mit einem Steuergerät, das außerhalb des Maschinengehäuses angeordnet und mit den Spulen elektrisch verbunden ist.The invention relates to an electric drive, in particular Electric axis, with at least one electrical machine, the one Has a plurality of coils in a machine housing, and with a control unit that is outside arranged of the machine housing and is electrically connected to the coils.
Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, einen Elektroantrieb der eingangs genannten Art zur Verfügung zu stellen, bei dem die elektrische Verbindung zwischen dem Steuergerät und den Spulen im Hinblick auf einen geringen Spannungsabfall und eine möglichst einfache Fertigung und Montage optimiert ist.The present invention lies the task is based on an electric drive of the type mentioned Kind available to make, in which the electrical connection between the control unit and the Coils with a view to a low voltage drop and one if possible simple manufacturing and assembly is optimized.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass das Maschinengehäuse eine Öffnung aufweist, die durch ein Klemmbrett verschlossen ist, das aus elektrisch isolierendem Material besteht und mit einer Mehrzahl von elektrisch leitenden, das Klemmbrett durchsetzenden Bolzen versehen ist, wobei an den innerhalb des Maschinengehäuses angeordneten Bolzenenden jeweils eine Spule angeschlossen ist und die außerhalb des Maschinengehäuses angeordneten Bolzenenden jeweils mit dem Steuergerät elektrisch verbunden sind.This object is achieved according to the invention solved, that the machine housing an opening has, which is closed by a clipboard made of electrical insulating material and with a plurality of electrical conductive bolt that passes through the clipboard is provided, wherein on the bolt ends arranged inside the machine housing one coil each is connected and arranged outside the machine housing Bolt ends are each electrically connected to the control unit.
Gemäß einer vorteilhaften Weiterbildung der Erfindung wird vorgeschlagen, dass die außerhalb des Maschinengehäuses angeordneten Bolzenenden jeweils mit einer Stromschiene in Eingriff stehen, die mit dem am Maschinengehäuse befestigten und benachbart zum Klemmbrett angeordneten Steuergerät elektrisch verbunden ist.According to an advantageous development The invention proposes that the arranged outside the machine housing Bolt ends are each engaged with a busbar that with the one on the machine housing attached and arranged adjacent to the clipboard control device electrically connected is.
Eine besonders günstige Verbindung zwischen den Spulen und den Bolzen ergibt sich dadurch, dass die Spulen jeweils mittels eines Kabelschuhes am zugeordneten Bolzen angeschlossen sind.A particularly favorable connection between the coils and the bolts result from the fact that the coils each are connected to the assigned bolt by means of a cable lug.
Zu diesem Zweck ist es von Vorteil, wenn die Bolzen jeweils an dem innerhalb des Maschinengehäuses angeordneten Bolzenende mit einem Gewinde versehen sind. Hierbei kann es sich z. B. um ein Innengewinde handeln.For this purpose, it is advantageous if the bolts are each arranged on the inside of the machine housing Bolt ends are threaded. It can be z. B. act on an internal thread.
Gemäß einer anderen günstigen Ausgestaltung sind die Spulen jeweils mit einer Klemmverbindung direkt am zugeordneten Bolzen angeschlossen. Dies kann beispielsweise dadurch erreicht werden, dass die Bolzenenden jeweils eine hülsenförmige Klemmvorrichtung aufweisen, in der das zugeordnete Spulenende angeordnet wird.According to another cheap one The coils are each designed with a clamp connection connected directly to the assigned bolt. For example can be achieved in that the bolt ends each have a sleeve-shaped clamping device have, in which the associated coil end is arranged.
Die Bolzen weisen mit Vorteil jeweils eine form- und/oder kraftschlüssige Verdrehsicherung auf. Hierbei besteht eine mögliche Variante einer Verdrehsicherung darin, dass die Bolzen jeweils über einen Längsabschnitt mit einem Vierkant- oder Sechskantprofil verfügen.The bolts each have an advantage a positive and / or non-positive Anti-rotation lock on. There is a possible variant of an anti-rotation device in that the bolts are each over a longitudinal section with a square or hexagonal profile.
Zweckmäßigerweise sind die Bolzen jeweils in axialer Richtung fixiert, beispielsweise durch einen Sicherungsring.The bolts are expedient each fixed in the axial direction, for example by a locking ring.
Sofern die Bolzen jeweils an dem außerhalb des Maschinengehäuses angeordneten Bolzenende mit einem Gewinde versehen sind, lässt sich eine optimale Verbindung zwischen den Stromschienen und den Bolzen erzielen. Dabei kann es sich z. B. um ein Außengewinde handeln.If the bolts on each outside of machine housing arranged bolt end are provided with a thread an optimal connection between the busbars and the bolts achieve. It can be z. B. act on an external thread.
Der erfindungsgemäße Elektroantrieb weist kurze Verbindungswege zwischen den Spulen und dem Steuergerät auf, wodurch die Ohm'schen Widerstände klein sind. Aufgrund der geringen Anzahl an Bauteilen werden die Fertigung und die Montage vereinfacht, was im Ergebnis zu Kosteneinsparungen führt.The electric drive according to the invention has short Connection paths between the coils and the control unit on, whereby the ohmic resistances small are. Due to the small number of components, manufacturing and simplifies assembly, which results in cost savings.
Darüber hinaus wird die Anzahl der widerstandsbehafteten Kontakte reduziert und der Spannungsabfall. Auch der Spannungsabfall an den einzelnen Kontaktstellen ist gering, da diese jeweils als feste, jedoch lösbare Verbindung ausgebildet sind. Insgesamt verfügt deshalb der erfindungsgemäß ausgestaltete Elektroantrieb über eine erhöhte Leistung und einen geringeren Energieverbrauch. Störende Kabelverbindungen zwischen dem Klemmbrett und dem Steuergerät sind nicht vorhanden.In addition, the number of the resistive contacts is reduced and the voltage drop. The voltage drop at the individual contact points is also low, since these are each designed as a fixed but detachable connection are. Total features therefore the one designed according to the invention Electric drive over an increased Performance and lower energy consumption. Disruptive cable connections are not present between the clipboard and the control unit.
Weitere Vorteile und Einzelheiten der Efindung werden anhand eines in den schematischen Figuren dargestellten Ausführungsbeispiels nähererläutert. Die Figur zeigt einen Schnitt durch einen erfindungsgemäßen Elektroantrieb.Other advantages and details of the invention are illustrated by means of one in the schematic figures embodiment nähererläutert. The Figure shows a section through an electric drive according to the invention.
