Die Erfindung betrifft eine elektrische Maschine, die zum Antrieb eines Kraftfahrzeugs geeignet ist, mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to an electrical machine, which is used to drive a Motor vehicle is suitable, with the features of the preamble of claim 1.
Statoren kleiner elektrischer Maschinen werden üblicherweise aus aufeinander geschichteten Blechringen, die eine Wicklung tragen, aufgebaut. Bei der Fertigung dieser Blechringe entsteht erheblicher Blechverschnitt. Die Wicklungen werden nach der Fertigung des Blechkörpers entweder direkt bzw. „räumlich" in die Nuten gewickelt oder sie werden nach vorheriger „ebener" Wicklung von Einzelspulen in einem zweiten Fertigungsschritt in die Nuten eingezogen. In bestimmten elektrischen Maschinen ist es möglich, so genannte Einzelwicklungen zu verwenden, bei denen die Spulenschrittweite eine Nutteilung beträgt. Bei solchen Wicklungen wird jeweils eine Spule um einen Zahn geschlungen.stators Small electrical machines are usually made out of each other layered sheet metal rings carrying a winding built up. at The production of these metal rings creates considerable sheet metal waste. The windings become after the manufacture of the sheet metal body either directly or "spatially" wound in the grooves or they are after previous "flat" winding of individual coils in one second manufacturing step fed into the grooves. In particular electrical machines it is possible use so-called single windings, where the coil step size a slot pitch is. In such windings, a coil is wound around a tooth.

Stromversorgung der auf dem Polbereich eines Statorsegments angebrachten Wicklung angeordnet ist. Die direkte Anordnung der Leistungselektronikeinheit auf dem jeweiligen Statorsegment hat den Vorteil, dass keine Leitungsverluste auftreten können. Der Gesamtwirkungsgrad der elektrischen Maschine steigt demnach. Weiterhin können die Leistungselektronikeinheiten wegen der direkten Anordnung auf dem Stator leicht an die Kühlung der elektrischen Maschine angekoppelt werden.The electrical according to the invention Machine with segmented stator structure is characterized by that on each stator segment a power electronics unit for Control or Power supply mounted on the pole portion of a stator segment Winding is arranged. The direct arrangement of the power electronics unit on the respective stator segment has the advantage that no line losses may occur. The overall efficiency of the electric machine increases accordingly. Furthermore you can the power electronics units due to the direct arrangement the stator slightly to the cooling be coupled to the electric machine.
Statorsegmente mit je einer Leistungselektronikeinheit und je einer Einzelpolwicklung können vorteilhafterweise vor dem eigentlichen Zusammenbau der gesamten elektrischen Maschine hergestellt werden. Ein aufwändiges Anbringen von Wicklungen und Anschließen einer Leistungselektronikeinheit nach dem Zusammenbau entfällt.stator each with one power electronics unit and one single-pole winding each can advantageously before the actual assembly of the entire electric machine getting produced. An elaborate Attaching windings and connecting a power electronics unit according to the assembly is omitted.
In Ausgestaltung der Erfindung ist eine zumindest teilweise ringförmige Verschienung, eine so genannte Zwischenkreisverschienung vorgesehen, welche die auf den einzelnen Statorsegmenten angeordneten Leistungselektronikeinheiten elektrisch miteinander verbindet. Eine derartige, vorzugsweise kreisförmige Zwischenkreisverschienung zeichnet sich dadurch aus, dass sie besonders einfach in eine elektrische Maschine integriert und an einen Stator angebracht werden kann.In Embodiment of the invention is an at least partially annular busbar, a so-called DC link bus provided, which the on the individual stator segments arranged power electronics units connects electrically with each other. Such, preferably circular DC busbar is characterized by the fact that it is particularly easy to use in an electrical Machine can be integrated and attached to a stator.

Erfindung betrifft elektrische Maschinen, bei denen die Statoren
bzw. die aufeinander geschichteten Blechringe, aus denen die Statoren
aufgebaut sind, in einzelne Segmente, so genannte Statorsegmente,
zerlegt sind. In
Die Segmentierung von Stator und/oder Rotor führt zu einer Reduzierung der Materialkosten, da der Blechverschnitt erheblich reduziert wird. Außerdem werden hierbei kleine Bleche in großer Stückzahl verwendet, was zusätzlich die Fertigungskosten auf Grund der hohen Stückzahl und der kleinen Werkzeuge reduziert.The Segmentation of stator and / or rotor leads to a reduction of Material costs, as the sheet metal waste is significantly reduced. In addition In this case, small sheets are used in large quantities, which additionally the Production costs due to the high number of pieces and the small tools reduced.

Sämtliche Maschinentypen mit Drehfeldwicklung, zum Beispiel eine Asynchronmaschine, eine Synchronmaschine und eine Reluktanzmaschine, können mit Einzelzahnwicklung ausgeführt werden. Besonders vorteilhaft kann die Einzelzahnwicklung bei permanenterregten Synchronmaschinen und so genannten Switched-Reluctance-Maschinen eingesetzt werden. Bei diesen Ma schinentypen führt die Verwendung von Einzelzahnwicklungen gegenüber klassischer Wickeltechnik zu einem Betriebsverhalten (insbesondere der durch diese Maßnahme erreichte hohe Feldschwächbereich und die hohe Ausnutzung), welches sich als besonders günstig erweist, wenn die elektrische Maschine als Antriebseinheit in einem Kraftfahrzeug eingesetzt wird.All Machine types with rotating field winding, for example an asynchronous machine, a Synchronous machine and a reluctance machine, can with single tooth winding accomplished become. Particularly advantageous, the single-tooth winding in permanent-magnet Synchronous machines and so-called switched-reluctance machines used become. For these machine types, the use of single-tooth windings leads across from classic winding technology to a performance (in particular the by this measure reached high field weakening area and the high utilization), which proves to be particularly favorable, when the electric machine as a drive unit in a motor vehicle is used.
Derartige Maschinen können mit unterschiedlichen Strangzahlen hergestellt werden. Mögliche Kombinationen sind beispielsweise 13-, 15- und 17-strängige Maschinen mit 13, 15 und 17 Statorzähnen und 12, 14 und 16 Rotorpolen. Entsprechend der Bildungsgesetze für modulare Dauermagnetmotoren und der Regeln für Bruchlochwicklungen sind selbstverständlich noch weitere Kombinationen denkbar.such Machines can be produced with different strand numbers. Possible combinations are, for example, 13, 15 and 17-strand machines with 13, 15 and 17 stator teeth and 12, 14 and 16 rotor poles. According to the education laws for modular Permanent magnet motors and the rules for broken hole windings are Of course even more combinations conceivable.
Einer der Vorteile der Einzelzahnwicklung ist, dass jede einzelne Zahnspule bzw. Zahnwicklung unabhängig von den anderen Zahnspulen bestromt werden kann. Daher kann auch jede Zahnspule von einer eigenen Leistungselektronikeinheit, die bevorzugterweise in der Nähe dieser Spule angeordnet ist, bestromt werden.one The advantages of single tooth winding is that every single tooth coil or tooth winding independently can be energized by the other tooth coils. Therefore, too each tooth coil from its own power electronics unit, the preferably in the vicinity This coil is arranged to be energized.
