Metal Additive Manufacturing (AM) offers unparalleled geometric freedom in the design of electrical machine windings, enabling new approaches to AC loss reduction, thermal management, and electrical insulation options that can unlock step changes in power-density and efficiency.

In this presentation, the state of the art in AM of coils and conductors will be presented, including design tool developments, challenges in manufacturing and post-processing, and the wide array of opportunities brought by AM. The benefits will be showcased through a recent Innovate UK supported case-study where AM delivered significant reduction in AC loss and minimised packaging volume of a high-speed automotive compressor applications, in collaboration with Technelec, UK. During this session we will deep dive on the following:

• Metal Additive Manufacturing (AM) offers new design freedoms in coil and winding production
• AC loss reduction improved thermal management, and opportunity for alternative electrical insulation systems will be discussed.
• The benefits of AM will be showcased through a high-speed automotive compressor application, developed with Technelec, UK.

During this session, we will discuss the findings from original experimental studies concerning lightning performance of a variety of dielectric liquids applied in power transformers. The issues presented come from the joint research of academia and industry. An approach to new types of tests aimed at verification of dielectric properties of insulating liquids will be presented.

• Presentation of experimental studies on the lightning performance of various dielectric liquids used in power transformers

Driven by the green energy transition, the demand for transformers is growing rapidly. Inside of a transformer, there is an extensive amount of paper and board which are made from pulp. To make sustainable transformers, we need low carbon pulp from sustainably managed forests.

• The increased demand for transformers will require growth in transformer board and paper, which form an integral part of any transformer design.
• To fulfill this demand responsibly, we need to use sustainable materials. Pulp from Nordic forests is sustainable and comes from sustainably managed forests.
• To guarantee long-term sustainability and a net positive impact on climate and biodiversity, we need to work both in the forest as well as increase the sustainability of the products, e.g. by lowering the carbon footprint.
• Join this session to learn about how forests are managed and used in a sustainable manner and hear more about what a tree can do.
