H3X Technologies’ Post

H3X has been awarded a $1.9M TACFI contract with the United States Air Force to advance hybrid-electric powerplants for eVTOL aircraft in military operations. We’re excited to build on our successful Phase II work with AFWERX and continue our collaboration. Electrified aircraft have the potential to provide the Air Force with a range of cost-effective crewed and uncrewed aircraft capable of performing new and valuable missions. These aircraft offer operational independence from traditional runways, increased maneuverability, and the ability to operate from decentralized bases. Hybrid-electric propulsion systems, which combine an engine with an electric machine to generate electricity for propulsion, are now making it possible to harness the benefits of electric motors while also leveraging the superior energy density of liquid fuels. This architecture allows for greater range and endurance, while also eliminating the need for charging infrastructure in forward operating locations, further enhancing their operational utility. This ensures that electric aircraft can meet operational requirements for mission success while benefiting from the strengths of both technologies.

Today we are announcing that we have officially closed our $20M Series A funding round! The round was led by Infinite Capital, with participation from Hanwha Asset Management Co., Ltd., Cubit Capital, Origin Ventures, Industrious Ventures, Venn10 Capital, LP, and follow-on investors that include Lockheed Martin, Metaplanet, Liquid 2 Ventures, and TechNexus Venture Collaborative. This funding will primarily be used to: 1. Scale up production and operations to deliver on some very large aerospace and defense contracts in our pipeline. 2. Finish development of our megawatt-class machines. 3. Continue to improve the robustness and reliability of our core technology through endurance, thermal cycling, and accelerated aging testing. We couldn't have reached this point without an amazing group of customers, advisors, investors, partners, and most of all, everyone at H3X. While we're celebrating this milestone, we will not rest on our laurels and will continue to push at a relentless pace towards our mission of becoming the world leader in electric motors to enable sustainable aviation, decarbonize the marine and industrial sectors, and unlock next-generation electrified defense technology.

The HPDM-140 has arrived! 🤘 IPM motor, SiC inverter, DMLS housing with synergistic cooling - all integrated in one mega power-dense package. The images below show the -140 coupled to our HPDM-30 for testing. First customer unit shipped out last week, ahead of schedule!

One of our customers asked us if we could de-integrate our axial inverter and sell it in a standalone package so they could use it to drive some pumps and other loads on their aircraft. We said sure, no problem. Two months later, we’re shipping out the first four HPDI-190s! Here are the notable features: + Silicon Carbide (SiC) three-phase inverter + Continuous Power: 190 kW (at PF=1) + Max Bus Voltage: 450VDC or 800VDC + Max Phase Current: 190 Arms + Mass: 2 kg + Power Density: 95 kW/kg + Peak Efficiency: > 99% + Control Modes: Torque, speed, generator (voltage setpoint) + Integrated common mode filtering If you need an extremely power dense inverter, shoot us a message!

140kW in a 11kg package ⚡ We present the HPDM-140, our most power dense integrated motor drive yet. The HPDM-140 builds off H3X's proprietary core technology and pushes the limits of what's possible with electric machines and power electronics through novel materials, advanced manufacturing technologies, and unparalleled integration. Shipping to select customers in August this year. For full specs, see link in comments. #motors #powerelectronics #aerospace #defense

We had the privilege of sitting down with Rory Jackson from our favorite magazine, E-Mobility Engineering, to discuss our technology and how we are pushing out the pareto curve of electric motor performance to unlock widespread commercial electric aviation. This cover story goes deeper than ever before and we uncover everything from the #electricmotor design to the #powerelectronics and the integration between them. If you take away one thing from this article, it should be that there is that there is no silver bullet. Getting to >10 kW/kg power density requires significant advancements in several different areas. While many competitors rely on complex topologies and traditional optimization techniques to achieve higher power density, the performance levels needed for electric aviation require us to go a step further by questioning the most fundamental assumptions that feed into the engineering optimization process. This has driven H3X to innovate on a deeper level with new materials, in-house manufacturing technologies, and novel integration techniques.

2023 was an amazing year for H3X. We hit some huge milestones in proving out our core technology, ramping up manufacturing, and commercialization. Here’s a quick recap of some of the major achievements: • Moved into our new 17,000 sq-ft headquarters facility in Louisville, CO and built out pilot production. • Closed key strategic investment from Lockheed Martin. • Achieved industry leading power densities of 12.5 kW/kg for the HPDM-250 and 8.5 kW/kg for the HPDM-30 on our dyno. • Manufactured over 25 motors. • Secured firm orders from some of the best aerospace and defense companies in the world working on everything from hypersonic aircraft to hydrogen-powered commercial aviation. • Shipped product to these customers. • Closed out our NASA contract ahead of schedule, won another one. • Completed all technical deliverables for our AFWERX Ph II contract. • Ground tested the HPDM-250 with our partner, Stralis Aircraft (YC W23), in their aircraft and successfully completed mission profiles ahead of our first flight next year. • Doubled the size of our team. Special thanks to our incredible customers, investors, partners, and, most of all, our team members and families for making this our best year yet. We’re about to kick it up a notch in 2024 and are fired up to get back to work and hit the ground running. Happy Holidays and Happy New Year from all of us at H3X.
