Modeling of Hairpin Winding in Ansys Motor-CAD
This paper demonstrates the bespoke modeling capabilities in Motor-CAD for the analysis and design of hairpin windings. The modeling method of the hairpin winding using Motor-CAD is shown, as well as design rules and checks in the software. Based on a representative traction motor example, the influence of introducing more winding layers on the copper losses has been analyzed, with the following conclusions:
- Using a higher number of winding layers does not always result in lower copper loss.
- The trade-off between DC and AC losses under different operating points should be considered when designing for the optimal number of winding layers.
