The HPDM-250 is an ultra-high power density integrated motor drive for electric aircraft. It combines the electric motor, inverter, and gearbox into one powerful unit. It is the culmination of H3X innovation in multiple areas including:
Electromagnetics design optimization
DMLS 3D printed synergistic cooling jacket
3D printed copper stator coils
Robust fault tolerance
Thermal resistance reduction
High frequency SiC power electronics
The HPDM-250 is optimized entirely for power density and efficiency. It features the highest level of integration on the market, made possible by our holistic design methodologies rooted in first principles and multidisciplinary expertise in power electronics and electric machines.
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.
High fill factor
Streamlined automated manufacturing
Scalable to high volume
Greater design freedom
Faster development cycles
A team of multidisciplinary engineers brought together with the sole purpose of developing the most advanced electric aircraft propulsion systems in the world to enable sustainable aviation.
For electric aircraft to be commercially feasible, substantial improvements need to be made to electric propulsion system technology. Today, best-in-class motors and inverters have a combined power density of 3-4 kW/kg. ARPA-E has determined that for a Boeing 737 to complete a typical five hour flight, the propulsion system must be >12 kW/kg continuous.
We have the solution.
At 13 kW/kg continuous, the HPDM-250 exceeds ARPA-E’s requirements and is at least 3X better than current systems. It is a step change in electric propulsion technology and removes one of the main barriers blocking widespread commercialization of electric aircraft.
Any mass-sensitive, packaging-constrained, or high performance application.
Near-term applications: Urban air mobility, military, electric boats, motorsports (F1), select regional aircraft markets.
Long-term applications: Large commercial electrified aircraft for short-haul flights less than 1000 miles.
H3X brings together driven minds from the automotive, aerospace, and motorsports industries with deep knowledge in electric propulsion systems and vehicle engineering. We love what we do and are looking to hire people who share that same passion.
As CEO, Jason is responsible for overall business direction and power electronics development at H3X. His speciality lies at the intersection of business leadership and hardcore engineering. Prior to H3X, he started his own engineering consulting company where he has helped several companies in the automotive and aerospace industries bring their EV product visions to life. He has a B.S. and M.S. in Electrical Engineering from University of Wisconsin-Madison. Fun fact - Jason (and Max) co-founded UW-Madison’s electric Formula SAE team and built the first AWD electric racecar in the United States.
Max is a multidisciplinary engineer with a laser focus on physics fundamentals and deep knowledge in both mechanical and electrical engineering. As CTO, he is responsible for H3X’s overall product engineering, electric motor design, and core technology development. Max’s background includes holding key roles in vehicle modeling, architecture, and electric motor design in both the automotive and aerospace sectors. He has a B.S. in Mechanical Engineering and an M.S. in Electrical Engineering from University of Wisconsin-Madison.
Eric is responsible for all operations and mechanical design at H3X. In Eric’s prior roles, he has lead projects to develop control systems for electric and hybrid powertrain systems from the ground up. He has a B.S. in Mechanical Engineering from University of Wisconsin-Madison. Eric comes from a proud heritage of craftsmen – from butchers and bakers to electricians and steamfitters. This unique background has enabled to him bridge the gap between advanced engineering theory to practical and scalable solutions.
