Description

Parallel zur Achse sich erstreckender, in lappenartige Ansätze endigender Wendepol für elektrische 1Kaschinen mit schrägen Ankernuten. Um in einer Wendepohnaschine ein möglichst wirksames Wendefeld zu erzielen, muß man oftmals den Wendepolschuh sehr schmal halten. Eine hinreichende Verringerung der Wendepolschuhbreite ließ sich aber z. B. bei Maschinen mit schrägen Ankernuten bisher nicht immer durchführen, ohne daß sich der eine Teil der Ankernut schon außerhalb des Wendefeldes befindet, während der andere Teil noch gar nicht in dessen Bereich gelangt ist.Extending parallel to the axis, ending in flap-like approaches Reversible pole for electrical 1-machine machines with inclined armature slots. To in a reversible machine To achieve the most effective turning field possible, you often have to use the reversible pole shoe keep it very narrow. A sufficient reduction in the reversible pole shoe width allowed but z. B. not always carried out on machines with inclined anchor grooves, without that one part of the anchor groove is already outside the turning area, while the other part has not yet reached its area.

Die Erfindung betrifft nun einen Wendepolschuh, der einerseits ein kräftiges Wendefeld schafft und anderseits ein gleichzeitiges Durchschreiten der schrägen Ankernut auf ihrer ganzen Länge hin durch das Wendefeld ermöglicht.The invention now relates to a reversible pole shoe, the one hand creates a strong turning field and on the other hand a simultaneous passage through the oblique anchor groove made possible over its entire length by the turning field.

Erfindungsgemäß erhält der Wendepolschuh, ;der auf einem großen Teil seiner Länge hin sehr schmal ist, an seinen beiden Enden auf entgegengesetzten Seiten in der Umfangsrichtung einseitig Lappen, so daß der Lappen an einem Ende des Polschuhes dem Lappen am andern Ende entgegengerichtet ist.According to the invention, the reversible pole shoe receives on a large part its length is very narrow, at both ends on opposite sides lobes on one side in the circumferential direction, so that the lobe is at one end of the pole piece is opposite to the flap at the other end.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Grundriß dargestellt. Die lappenartigen Vorsprünge sind mit a und b, die Längsachse des Wendepolschuhes mit W-W bezeichnet. Die schräge Nut des Ankers ist durch die gestrichelten Kantenlinien angedeutet. Aus der Zeichnung ist ersichtlich, daß sich die Nut beim Durchschreiten des Wendefeldes auf ihrer ganzen Länge hin gleichzeitig in dessen Bereich befinden kann.In the drawing, an embodiment of the invention is shown in plan. The tab-like projections are designated with a and b, the longitudinal axis of the reversible pole shoe with WW. The inclined groove of the anchor is indicated by the dashed edge lines. It can be seen from the drawing that the groove can be located in its area over its entire length when passing through the turning field.

Die Lappen können, wie in der Zeichnung veranschaulicht, mit dem Polschuh aus einem Stück bestehen. Sie können aber auch für sich hergestellt und an dem Polschuh befestigt werden. Bei manchen Maschinen können sie auch an Keilen befestigt werden, die sich an den Polschuh anlehnen und die zwischen jedem Polschuh und dem benachbarten Zahn liegende Wicklung abstützen.The tabs can, as illustrated in the drawing, with the pole piece consist of one piece. But they can also be made for themselves and attached to the pole piece be attached. On some machines they can also be attached to wedges, which lean against the pole piece and those between each pole piece and the neighboring one Support the tooth winding.

PATENTANSPRUCH: Parallel zur Achse sich erstreckender, in lappenartige Ansätze endigender Wendepol für elektrische Maschinen mit schrägen Ankernuten, dadurch gekennzeichnet, daß jene Ansätze (a, b) einseitig angeordnet sind, und zwar so, daß sie in der Umfangsrichtung des' Ankers nach entgegengesetzten Seiten vorspringen. Claim: Reversing pole extending parallel to the axis and ending in tab-like approaches for electrical machines with inclined armature grooves, characterized in that those approaches (a, b) are arranged on one side, namely in such a way that they are in the circumferential direction of the 'armature on opposite sides protrude.
