How powerful is the magnetic field in typical brushless motor? Even if it can’t be used for an MRI machine, it could do wonders for efficient (and/or compact) robotics and electric vehicles.

I’m also very curious what kind of inductors you could make for switching power supplies using superconductors.



1.5-2 Tesla you hit the knee of the BH curve and you saturate the steel.


Do you need steel? What about a brushed(Assume some fancy future micrometer gallium filled gap that doesn't wear or something) motor that just has superconducting coils attracting each other?


Yeah I guess if you have superconductors you prob don’t need steel. Bonus, no cogging.


Can't wait to replace all the resistors in my PSU with SuperConducting Resistors. :-)
