Innovative strength – government-sponsored project focused on high-performance electric motors for high-voltage systems comes to a fantastic conclusion

After a brief two-and-a-half-year period, engineers from Unterföhring have completed a project to develop high-performance electric motors for high-voltage systems. Funded by the German Federal Ministry for Economic Affairs and Energy as part of the Central Innovation Program for SMEs (ZIM), the result was an ultra-compact electric motor that represents yet a further milestone on the road to sustainable mobility.

During development, a lot of attention was paid to the motor’s applicability in avionics, for example for air taxis. The units are characterized by maximum efficiency and power density, so the technical challenge was to ensure the best possible cooling in the smallest possible installation space. This was the starting point for LSP. From 20 different designs, the three most promising concepts were selected and brought to prototype maturity. Testing ultimately showed a significant increase in performance of up to 20% over nominal output.

What made this impressive improvement possible was a combination of innovative materials, optimized heat transfer and additive manufacturing, which allowed individual components to be built layer by layer. Building on these successes, LSP GmbH’s next step will be to approach customers in the avionics industry, but overall development is far from complete. Currently, optimized power electronics for redundant operation are being designed to meet the obviously more stringent safety requirements of the aviation industry. The challenge here will be to integrate all of the essential components into a highly compact power pack.
