Lockheed Martin Ventures Invests In Electric Motor Company H3x Lj Aero H3x launches evtol electric motor “three times more efficient than current types”. november 11, 2020 philip butterworth hayes air taxis and personal transports. minneapolis based h3x has launched what it claims to be an integrated electric motor design, the hpdm 250, that can provide sustained power as some of the best electric aviation. The hpdm 1500 is an ultra high power density multisector imd for primary propulsor applications on large electric aircraft and marine vessels. based on the same core technology as the h3x hpdm 250, this epu has a continuous specific power of >10 kw kg and features the highest level of fault tolerance and reliability with its 8 independent drive.
H3x Ships Advanced Electric Drives For Customer Testing Aviation Week The 18.7 kg (41.2 lb) motor weighs a little more than the projected 15 kg (33 lb) 250 unit from back in 2020, owing largely to its integrated 6.7:1 gearbox, but still pulls off an impressive power. Fortunately, h3x’s motors seem tailor made for this application (and indeed in a sense can be said to be so). first, the design is reversible, meaning it can seamlessly act as a motor or a. The issue when it comes to electric flight is power versus mass. the startup h3x says it has developed a compact electric motor that develops more than 3 times the power and weighs less than most. H3x hpdm 250 electric aircraft motor design. the first version will weigh 15 kg (33 lb) and make 200 kw of continuous power, peaking at up to 250 kw. that's 13.3 continuous kilowatts per kilogram.
