Abstract

In derselben Ebene eines lamellierten Kernpaketes (5) befindliche Jochlamellen (11) für ein lamelliertes Jochteilpaket (51) und Pollamellen (12) für ein lamelliertes Polteilpaket (52) werden jeweils durch Teilschnitte gefertigt. In einem mittleren Schenkel (112) des Bereiches der Jochlamelle (11) ungefähr symmetrisch zu und ungefähr parallel zu der Längsachse des Schenkels (112) werden zwei ungefähr gleich lange und zueinander parallele einfache Trennteilschnitte (a, a') durchgeführt, die zusammen mit Teilschnitten (b, c2, c2') den mittleren Schenkel (112) von der Pollamelle (12) trennen. Danach wird der mittlere Schenkel (112) mit Teilschnitten (c1, c1'), die auf der einen und der anderen Seite der parallelen einfachen Trennteilschnitte (a, a') ungefähr senkrecht zu diesen und in der Verlängerung voneinander verlaufen, zurückgeschnitten.In the same level of a laminated core package (5) existing yoke blades (11) for a laminated Yoke part package (51) and pollen slats (12) for a laminated one Pole pack (52) are each by partial cuts manufactured. In a middle leg (112) of the area the yoke lamella (11) approximately symmetrical and approximately parallel to the longitudinal axis of the leg (112) are two approximately the same length and parallel simple ones Partition cuts (a, a ') performed together with Partial cuts (b, c2, c2 ') the middle leg (112) of separate the pollamelle (12). After that, the middle one Leg (112) with partial cuts (c1, c1 ') on one and the other side of the parallel simple Partition cuts (a, a ') approximately perpendicular to these and in extending from each other, cut back.

Zwischen den nach dem vervollkommneten Verfahren gefertigten lamellierten Teilpaketen (51, 52) des Joches beziehungsweise des Poles werden eine gute mechanische Verbindung und eine zeitlich stabile magnetische Verbindung ermöglicht. Die Aufschiebekraft und die Ausziehkraft ändern sich nicht mit der Zahl der Aufschiebungen.

Figure 00000001
A good mechanical connection and a temporally stable magnetic connection are made possible between the laminated partial packets (51, 52) of the yoke or the pole manufactured according to the perfected method. The postponement force and the pull-out force do not change with the number of postponements.
