The lightest electric aircraft motors in the world.

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.

Eric Maciolek
Founder
I am responsible for all operations and mechanical design at H3X. In prior roles, I have led projects developing control systems for electric and hybrid powertrain systems from the ground up. I have a BS in Mechanical Engineering from University of Wisconsin-Madison. I come from a proud heritage of craftsmen – from butchers and bakers to electricians and steamfitters. This unique background has enabled me to bridge the gap between advanced engineering theory to practical and scalable solutions.
