Description

Die. Herstellung der Bleche -für die Ständerpakete elektrischer Maschinen erfolgt meist so; daß im Folgeschnttverfahren :die einzelnen Bleche aus Blechstreifen nacheinander ausgeschnitten oder ausgestanzt werden. Bei der üblichen runden Form der Bleche entsteht dabei ein erheblicher Blechabfall, der das Herstellungsverfahren unwirtschaftlich macht.The. Production of the sheet metal - for the stator packs of electrical machines is usually done like this; that in the sequential cutting process: the individual sheets are cut out or punched out from sheet metal strips one after the other. With the usual round shape of the sheets, a considerable amount of sheet metal waste arises, which makes the manufacturing process uneconomical.

Gemäß ,der Erfindung 'kann dies dadurch vermieden und dabei noch .die Herstellung der Bleche wesentlich vereinfacht werden, wenn die Ständerbleche eine sich der viereckigen Form möglichst nähernde Gestalt erhalten. Dadurch ist es möglich, die aufeinanderfolgenden Bleche durch einen einfachen geraden Schnitt ohne wesentlichen Abfall voneinander. zu trennen: Eventuelle Unebenheiten am Umfang der Bleche werden vorteilhaft durch ein Umspritzen des Ständerblechpaketes ausgeglichen. Die Ecken der Ständerbleche können hierbei im wesentlichen beibehalten werden und dienen als Kühl- oder Haltekörper. Das Ständerblech wird zweckmäßig derart in Spritzguß eingebettet, daiß, ein die Ecken der Ständetbleche harmonisch aufnehmender gewellter oder mit Spitzen oder Rippen versehener Umriß entsteht.According to "the invention" this can be avoided while still .the Manufacture of the sheets are significantly simplified if the stator sheets a obtain a shape that is as close as possible to the square shape. This makes it possible the successive sheets by a simple straight cut without essential Falling apart from each other. to be separated: Any unevenness on the circumference of the sheets will be advantageously compensated for by overmoulding the stator core. The corners the stator plates can essentially be retained and serve as Heat sink or holding body. The stator plate is expediently embedded in injection molding in such a way that daiß, a corrugated or with Pointed or ribbed outline is created.

In der Zeichnung ist ein Ausführungsbeispiel eines Ständerblechpaketes dargestellt. Die Bleche i haben etwa rechteckige Form und ihre Ecken 2, die Kühlrippen bilden, liegen zwischen aufgespritzten Rippen 3 und ,4.The drawing shows an embodiment of a stator core shown. The sheets i have an approximately rectangular shape and their corners 2, the cooling fins form, lie between sprayed-on ribs 3 and 4.
