About
At H3X, we are making the lightest, high-power electric propulsion systems in the world to enable a large-scale revolution in aircraft electrification. Our first product is a 250-kW (335 HP) integrated motor drive in an 18 kg package. It combines the electric motor, inverter, and gearbox into a single powerful unit and is the culmination of patent pending innovation in multiple areas.
