Aerospace demands high power density, efficiency, and reliability — H3X's products deliver all three to power the future of flight.
In airborne applications, every kilogram counts. Our products deliver 8-12 kW/kg continuously at direct-drive speeds, eliminating the need for a gearbox — reducing maintenance and complexity.
With peak efficiencies up to 97%, our products minimize energy storage and heat rejection needs, allowing for significant weight and drag reductions at the aircraft-level.
Our multisector architecture ensures fault tolerance and safety for aviation, with each drive sector electrically, magnetically, and thermally isolated from one another — allowing for continued operation even after an electrical failure.
Built to aerospace-grade standards, our products deliver the durability, reliability, and performance demanded in the most challenging flight environments.
Aviation is at a pivotal point in history. It’s one of the fastest growing sectors of greenhouse gas emissions, and we need to take aggressive action towards decarbonization to meet global climate goals, including those outlined in the Paris Agreement and the White House's Net-Zero Game Changers Initiative.
Aircraft are very sensitive to mass. Current aviation-grade megawatt-class electric motors have power densities in the 3-4 kW/kg range. This is not sufficient and will result in aircraft with suboptimal range that is prohibitive for commercial operations. Numerous studies have been done and the general consensus is we need >10 kW/kg for commercially viable regional and single-aisle electric aircraft.
H3X was founded to solve this problem and create the enabling technology for electric aviation, specifically Regional Air Mobility. We have developed novel integrated motor drive technology scalable to the MW-class with power densities >10 kW/kg and cruise efficiencies as high as 97%.
H3X's multisector products shown below are designed for primary propulsion on aircraft and are intended to be certified via Part 33 through the FAA.
