Does this motor design scale down? It's not clear from the article - the article focuses more on the relative efficiency gains over the previous model.
A 30lb 1000hp motor doesn't necessarily mean that they can also produce a 3lb, 100hp motor. It would be cool if it did, but I doubt that it does because usually component strength doesn't scale linearly.
That being said, these are still valuable for traditional EVs. Even if they are only a modest weight savings in the grand scheme of modern vehicle weight, their ability to improve packaging options will be a boon. One thing the industry has dicovered is that the generic "skateboard" platform doesn't make for the best vehicles, in terms of packaging.
- NathanKP 1y agoI'm more fascinated by the question of whether it scales up... imagine much smaller and more efficient electric engines for cruise liners and cargo ships.
- ApolloFortyNine 1y agoYour average cruiseship already has an electric engine, they just have massive generators onboard to power it.
- lazide 1y agoNotably, it’s probably also not very efficient, and eventually they’ll likely upgrade with some of the improvements from these types of motors to save on fuel.
- RogerL 1y agoThe article and the press release it was derived from says nothing about "more efficient", just smaller. https://yasa.com/news/yasa-smashes-own-unofficial-power-density-world-record-pushing-state-of-the-art-electric-motor-to-staggering-new-59kw-kg-benchmark/ https://yasa.com/news/yasa-smashes-own-unofficial-power-dens...
