Optimised hairpin stators for the automotive sector!
In a collaborative research project with Ford Motor Company, we have optimised a hairpin stator to achieve higher efficiency and better packaging.
Thanks to the combination of hairpin conductors with a constant cross-section, variable profile and our optimized production technologies, we were able to improve the end winding and reduce the length by 25 % and the resistance by 18 %!
PEEK insulation is used to avoid effects such as partial discharge and to ensure durability. The material has excellent dielectric behaviour, high abrasion resistance and very good chemical compatibility with the transmission fluid. Since the end of the project, Additive Drives has developed other thin film insulation systems with high performance materials.
The production of the stators is carried out in a very short time and without tooling costs. This makes the development of new electric motors simpler than ever!
