minus-squareSkyrmir@lemmy.worldlinkfedilinkEnglisharrow-up5·1 month agoMore torque per weight of motor, or more power generated per torque applied to it.
minus-squaregandalf_der_12telinkfedilinkarrow-up1·1 month agoi 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.
minus-squareironeagl@sh.itjust.workslinkfedilinkarrow-up2·1 month agoAlso 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.
