The economic production of automotive electric drives challenges manufacturers and OEMs. In order to support the cost optimal technology choice, a real lamination stack production is assessed with respect to quantity and variant flexibility. Therefore the process chain of a sample product is analyzed from the coil material to the finished stack. The cost interdependencies are analytically modeled in order to calculate the production costs from a bottom-up perspective. The cost calculation is done for a punching as well as a laser-cutting line. Based on this evaluation manufacturing processes can be chosen and volume-flexible series production lines can be designed. Furthermore, the achievable quality is a key aspect in the production of electric drives. The geometric features of the single sheet and the lamination stack, respectively, influence the performance of the electric drive significantly. Therefore, the perspective on suitable evaluation criteria for the processdependent quality characteristics of the individual components is given in this paper.
