Validation through partial demonstrators

“Axial flow machines are currently characterized by relatively low production volumes, manufacturing processes that are not yet fully developed, and special requirements in terms of tolerances and design processes”, says PEM Director Professor Achim Kampker. “NAFTech” therefore pursues an integrated approach to topology, multi-domain machine design, and production methods, supported by data-based optimization of tolerance chains. During the project, the simulative design of the machine and the suitability of the manufacturing processes will be validated with the aid of specially constructed partial demonstrators.

AF-SynRM promises economic advantages, especially for small and medium-sized enterprises (SMEs), as it enables stable production costs and reduces dependence on volatile prices, which are prevalent with rare-earth magnets. “A magnet-free motor generally also reduces material costs by up to 50 percent, which can strengthen the competitiveness of SMEs and lower barriers to market entry”, Kampker says. Meanwhile, there is growing pressure to develop sustainable solutions to reduce carbon emissions and comply with legal requirements. According to PEM, early investment in magnet-free technologies can give SMEs an innovative edge and open up opportunities in high-growth markets. Photo above courtesy of IEEE Explore.
