Patent attributes
The invention relates to a laminated core for electromagnetic applications with at least two segments (2), of which at least one on a side-edge (11), comprises an engagement groove (12) and the other at an opposite side-edge (9) comprises a corresponding engagement projection (10), via which the two segments (2) are connected to one another into a component, wherein the engagement groove (12) comprises an undercut in the form of a widened section (26) distanced to the groove opening, and the engagement projection (10) and the engagement groove (12) are dimensionally matched to one another in a manner such that the engagement projection (10) and/or engagement groove (12) are plastically deformed by way of inserting the engagement projection (10) into the engagement groove (12), so that the engagement projection (10) engages into the widened section (26) of the engagement groove (12), as well as to a method for the manufacture of such a laminated core.
