A Colorado Firm Claims It Can Triple the Power of Electric Engines
An anonymous reader quotes a report from InterestingEngineering: Energy densities of lithium-ion batteries haven't reached the potential where long-range flights can be undertaken. So, a Colorado-based startup, H3X, looked to the electric motor for ways to improve its power capacity. The team started from scratch, looking at the various components of the electric motor. Comprised of a gearbox, a power delivery system, and a main motor, these components are usually housed separately to allow sufficient cooling space, without which could result in engine failure. However, using advances in material science and electronics, coupled with the ability to 3D-print structures such as copper, the team managed to put all components together into a single housing that weighs just 33 pounds (15 kg) without impacting their cooling needs. Their motor, called the HPDM-250, is much smaller than their contemporaries and has a lesser mass as well. The company claims that, according to the Advanced Research Projects Agency-Energy (ARPA-E) guidelines, a propulsion system of a commercial aircraft such as Boeing 737 must deliver a continuous power density of 12 kW/kg. However, conventional electric motors can only generate a maximum of up to 4kW/kg. Thanks to its reduced weight, the HPDM-250's power density clocks up to an impressive 13kW/kg. According to H3X, this is sufficient to power any mass-sensitive or high-performance application such as electric boats and has urban air mobility applications. Among the other targets for the company that remain in the distance are short-haul, large commercial flights in the sub-1000 mile range. Max Liben, Chief Technology Office at H3X, told TechCrunch that using advanced technologies made the manufacturing of their electric motor less laborious and yet not very expensive. Even when putting the components together, the team was conscious of maintenance needs and has ensured that servicing their motors is hassle-free as well. Whether powered by electric batteries or hydrogen fuel, these advanced electric motors are likely to play a role in enabling electric air mobility, even over longer distances.Read more of this story at Slashdot.
