The main objective in the development of electric drives is the continuous effort to increase the performance. One possibility to achieve this is the use of shaped litz wires. However, shaped litz wires present major challenges regarding the contacting process. In the preparation of the contacting process, the individual conductors of the litz wires must be completely stripped without residues and brought into a defined geometry. This preliminary process step is also known as compacting. The compacting process is the basis for the subsequent contacting of the litz wires with each other or with contact elements. One process for contacting the litz wires is laser beam welding. In the context of this publication, the process chain consisting of ultrasonic compacting and laser beam welding is evaluated. The focus is put on the possible variations of the litz wire topologies, which differ in single wire diameter, number of wires and degree of insulation. Depending on this, parameters for the two processes are elaborated. To evaluate the results, electrical and mechanical testing of the litz wire connections is carried out. In addition, different approaches for the qualification of the compaction quality, in particular the evaluation of insulation residues, are considered.
