Electrical machine topologies have been traditionally limited by the manufacturing methods available. The electric steel laminations normally used to minimize core losses make geometries other than 2D extruded difficult and expensive to manufacture. In the same way, the layout of the windings is also limited by both the wire geometry and size, as well as the insertion method and the end-turn arrangement. This is particularly challenging when using square conductors, since they cannot be bundled and bent in the same way as thinner round wires. However, new manufacturing methods, such as additive manufacturing, enable a much larger geometry flexibility.

The German company Additive Drives (invited to the Workshop) has developed several products using this technology, and counts with VW, Porsche, Rolls Royce, Ford, Toyota and Airbus among their customers. In Sweden, RISE has established an Application Centre for Additive Manufacturing in order to promote the adoption of the technology across Sweden, thus contributing to a sustainable transition and resilient value chains. Together, Lund University and RISE run a SEC funded prestudy to investigate how the additional design freedom provided by Additive Manufacturing can be used to enhance cooling in the end-windings. In this Workshop, we will learn from the experiences of both Additive Drives and RISE Application Centre for Additive Manufacturing.

Moreover, we will have the opportunity to visit RISE facilities and take a look at their equipment to gain firsthand experience on the manufacturing possibilities. The day will conclude with a joint exercise to identify interesting research topics and collaboration opportunities.
