Abstract



Driven by electric mobility
innovative winding methods increasing the copper fill ratio and thus the power
density of electrical drives gain in importance. Compared to conventional
windings, bar-wound windings based on rectangular cross sections besides
optimized copper fill ratios also offer advantages in terms of automated
production. Because of the high number of joints necessary for the
manufacturing of the winding, contacting efforts increase significantly
wherefore the process of laser welding, due to its short process times and high
reproducibility shows potentials to realize the process step. This paper
examines the most important interactions within the process of laser welding of
insulated copper wires with rectangular cross sections in the context of
electric drives production. Besides workpiece specific factors, the focus is
set on process parameters, beam guidance strategies and specific quality
requirements. For this purpose, a parameter study based on design of
experiments is executed in which suitable measuring technologies are used to
quantify the properties of the samples.
