Abstract
The laminated core () comprises laminations (), which are arranged one over the other and which are each connected to each other by means of a first connection (). In addition, at least some of the laminations () are connected to each other by means of a second connection (). By using two connections, the advantages thereof can be bundled, whereby the number and/or size of the connection points can be reduced while the requirement for the laminated core () remains the same or very high requirements for the laminated core () can be met or even increased. Advantageously, an adhesive is used as one of the connections (), while the other connection () can be a form-fitting connection. The adhesive () is applied to the lower side () and/or upper side () of the laminations () before or after the punching of the laminations (). However, the two connections can also be formed by two adhesive systems. Finally, the connections () can also be formed by at least one weld seam and additionally by an adhesive.
