There are also non rare earth magnets being explored. Niron - Iron nitride - magnets and ultrasonic compaction and other tech that wasn't feasible a while back are now becoming very practical. Japan could probably get to a dominant place with a solid research program, it'd give them a huge advantage for EVs and other motors.
- wisplike 7mo agoDont forget about good old externally excited motors like what Renault uses, no rare earths needed.
- observationist 7mo agoDefinitely, and new engineering around axial flux / pancake motors are getting really exciting. 1000 HP motors in a single wheel - 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... Incredible what can be done. If Japan ever wants actual mecha warriors for their military, they're going to need motors like that.
