As part of the “Central Innovation Program for SMEs” (ZIM) from the Federal Ministry of Economic Affairs and Energy, LSP has been working on the development of a high-performance electric motor for high-voltage systems since 2018. For their work, engineers at the Unterfoehring-based operation decided on the concept of a permanently excited synchronous machine that can be scaled up to an output of 100 kW. The new motor is suitable for voltages ranging from 230 V – 400 V.

By using ceramic cooling elements and novel high-temperature resistant polymers, LSP was able to form the basis for developmental success. These innovative materials, combined with an additive manufacturing process in which individual components were built up layer by layer, allowed for enormous flexibility and ultimately an ultra-compact design with the highest performance metrics. The power and torque characteristics of LSP’s new high-voltage motor can also be adapted to whatever application is currently at hand.

The high power density of up to 8 kW/kg as well as its high efficiency rating make the new HV motor a further milestone on the road to more sustainable mobility.
