You get by without the fancy iron teeth mechanical support they invented as long as you remain small enough. The main issue is miniaturizing magnet manufacture without per-magnet costs staying fixed.
I judge by COTS pricing, but the $/kW falling on magnets increases a lot below 5~15kW electrical.
- Robotbeat 7y agoYeah, if you have really tiny rare earth magnets, their cost-per-weight (for a given magnetic energy product) goes up a lot. Just finicky to deal with sintering a bunch of small things, I suppose.
