Die
Erfindung geht aus von einer elektrischen Maschine, insbesondere
einem elektrisch erregten Klauenpolgenerator für ein Kraftfahrzeug, nach dem
Oberbegriff des Anspruchs 1. Hierzu ist aus der
Offenbarung der ErfindungDisclosure of the invention
Erfindungsgemäß wird vorgeschlagen, dass die Haltebleche für die Permanentmagnete jeweils wenigstens eine zusätzliche Arretierung aufweisen, mit der sie sich in axialer Richtung an den Polen abstützen und damit eine axiale Verschiebung verhindern. Eine besonders preiswerte und wirksame Arretierung der Haltebleche an den Polen lässt sich hierbei realisieren, wenn die zusätzlichen Arretierungen an den Halteblechen als Lappen ausgebildet sind, die vorzugsweise zu den Polen hin abgebogen oder abgewinkelt sind und sich an wenigstens einem axialen Endabschnitt der Pole abstützen.According to the invention, it is proposed that the retaining plates for the permanent magnets each have at least one additional locking, with they are supported in the axial direction of the poles and thus prevent axial displacement. A particularly inexpensive and effective locking of the retaining plates at the poles can be realize when the additional locks on the Holding plates are designed as a flap, preferably to the Poland are bent or angled out and at least support an axial end portion of the poles.
Bei einer als Klauenpolmaschine ausgebildeten elektrischen Maschine ergibt sich eine besonders einfache und zweckmäßige Gestaltung der Arretierungen, wenn an den Halteblechen vorspringende Lappen sich an den Polfingerspitzen abstützen, weil in diesem Fall ohne zusätzliche Bearbeitung der Klauenpole Überstände der Bleche im Bereich der Polwurzel vermieden werden. Andererseits erreicht man jedoch eine wirksame Abstützung der Haltebleche an den Polen auch durch eine Abstützung an den Polwurzeln, wobei im Falle einer seitlichen Abstützung von Lappen an den Polwurzeln vorzugsweise jeweils mindestens eine Aussparung vorgesehen wird für den Eingriff der Lappen an den Halteblechen der Permanentmagnete. Hierdurch wird es möglich, die Arretierungslappen an den Blechen abzubiegen ohne Überstand an der Polwurzel. Weiterhin kann es vorteilhaft sein, eine axiale Arretierung an beiden axialen Enden der Haltebleche vorzusehen, wobei eine besonders sichere Arretierung der Bleche erreicht wird, wenn jeweils an deren beiden Enden beidseitig Arretierungen, vorzugsweise in Form von Blechlappen ausgebildet werden.at a trained as Klauenpolmaschine electric machine results in a particularly simple and convenient design of the locks, if on the retaining plates protruding lobes at the Polfingerspitzen support, because in this case without additional Processing the claw poles projections of the Sheets in the area of the pole root are avoided. On the other hand you reach however, an effective support the holding plates at the poles also by a support the pole roots, wherein in the case of a lateral support of Lobe at the pole roots preferably at least one recess is provided for the engagement of the tabs on the retaining plates of the permanent magnets. This makes it possible, the Turn locking tabs on the sheets without overhanging at the pole root. Furthermore, it may be advantageous to have an axial To provide locking at both axial ends of the retaining plates, a particularly secure locking of the sheets is achieved if at both ends thereof on both sides detents, preferably be formed in the form of sheet metal tabs.
Zur Erleichterung einer exakten Positionierung der Permanentmagnete und der Haltebleche ist es zweckmäßig, wenn die Arretierungen an einem axialen Ende der Bleche vor ihrem Einfügen zwischen den Magnetpolen angebracht werden, weil sich so die Arretierungen gleichzeitig als Einschubbegrenzung für die Bleche mit den zuvor an ihnen befestigten Permanentmagneten verwenden lassen.to Relief of an exact positioning of the permanent magnets and the retaining plates, it is useful if the locks at one axial end of the sheets prior to their insertion between the magnetic poles be attached, because so the locks simultaneously as Einschubbegrenzung for the Use metal sheets with the permanent magnets previously attached to them to let.
