Estimating the term…
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.
A laminated core for electromagnetic applications with at least two segments (2), of which at least one at a first side-edge (11) comprises an engagement groove (12), and the other at an opposite second side-edge (9) comprises a corresponding engagement projection (10), via which the two segments 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) extends from the second side-edge (9) and comprises a free end and a web (16) that connects the free end to the second side-edge (9), and wherein the engagement projection (10) and the engagement groove (12) are dimensioned to one another in a manner such that at least one of the free end of the engagement projection (10) and the engagement groove (12) is elastically deformed by way of inserting the engagement projection (10) into the engagement groove (12) and at least one of the free end of the engagement projection (10) and the engagement groove (12) is 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) to establish a secure locking connection.
A method for manufacturing a laminated core, with which the laminated core is assembled into a component from at least two adjacent segments (2), of which at least a first segment at a side-edge (11) comprises an engagement groove (12), at least a second segment at an opposite side-edge (9) comprises a corresponding engagement projection (10), the method comprising:
A linear chain for electromagnetic applications having a plurality of stator segments (2) for forming an annular stator, one of the plurality of stator segments at one end of the chain having a side-edge (11) comprising an engagement groove (12), and another of the plurality of stator segments at an opposite end of the chain having an opposite side-edge (9) comprising a corresponding engagement projection (10), via which at least two of the stator segments 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, the engagement projection (10) and the engagement groove (12) being dimensioned to one another in a manner such that at least one of the engagement projection (10) and the engagement groove (12) is elastically deformed by way of inserting the engagement projection (10) into the engagement groove (12) and at least one of the engagement projection (10) and the engagement groove (12) is 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) to establish a secure locking connection.
