Hyperdrives Ultra
- Integrated electric drive unit
- Stand-alone e-motor
Designed for the most demanding use in aviation and beyond. Delivers world-class continuous power density of > 12 kW/kg at superior load cycle efficiency. Available as an integrated system with SiC inverter and as a stand-alone motor.
Features and applications
Next level power.
Hyperdrives Ultra boosts unparalleled continuous power density of more than 12 kW/kg on a system level including our SiC inverter. Ideal for (hybrid-) electric aviation and all other applications that require the absolute maximum in continuous power density and efficiency.
Power. Continuous.
Hollow-conductor cooled hairpin architecture delivers 3× continuous currents (> 75 ARMS/mm²) and > 12 kW/kg continuous incl. inverter
Integrated system
Available as integrated power unit with high power dense three-phase SiC inverter and one shared cooling loop or stand-alone motor only
Rotor agnostic
Distributed winding layout allows for use of all rotor topologies (SPM as standard) and enable excellent NVH through low frequencies
Highly versatile
Best-in-class power-density and performance-to-cost for use as a motor or generator unit across aviation and high-performance
