The H3X HPDM 250 is the next step in the evolution of electric propulsion technology, with unrivaled power density – 13 kW/kg continuous.
The HPDM-250 features the highest level of integration on the market, is an ultra-high power density integrated motor drive for electric aircraft.
It combines the electric motor and inverter (+ optional gearbox) into one powerful unit. 250kW in a 15kg package.
It is the culmination of H3X innovation in multiple areas including:
Electromagnetics design optimization
DMLS 3D printed synergistic cooling jacket
SLM 3D printed copper stator coils
Robust fault tolerance
Thermal resistance reduction
High frequency SiC power electronics
H3X has developed a new kind of stator coil that is additively manufactured using pure copper with >93% IACS conductivity.
“Our AMcoils achieve >70% copper fill factor in the HPDM-250 and offer a 40% improvement over conventional windings in terms of maximum continuous current density.”
