Palm-sized magnet reaches 42 tesla, approaching the strength of the world’s most powerful magnets while using a few thousand times less power and over 1,000 times smaller coil volumes (interestingengineering.com)

more powerful

what does "more powerful" mean in this context? higher efficiency? or higher max torque?

[–] Skyrmir@lemmy.world 5 points 1 week ago (1 children)

More torque per weight of motor, or more power generated per torque applied to it.

i see so just more lightweight motors/generators then.

which makes sense considering that magnets are the functional part of the device and everything else is just there to provide mechanical stability.

Also better efficency. If you're throwing 10% of your output power just heating up a regular motor, then you grt a 10% boost using a superconducting motor. Or something like that.

Much higher efficiency these take little power relatively.
