"high-speed motor for a fuel cell compressor to enable innovation in the utility vehicle and aviation domain. The electric machine should at least achieve a power density of 30 kW/kg by using innovative materials for direct cooling of the stator and maximizing the rotor's high-speed capability (< 150,000 rpm). The rotor design will use a new manufacturing process to glue and pot the magnets to be suitable for high circumferential speeds"
