Re: magnetism question

A non-stick pan doesn't have to contend with changes in dimensions of the
rotor and stator as they heat up and put the squeeze on. There is also the
problem that nothing is "perfectly true". This increases with the size of
the machine. The limitations are mechanical.
I ran an experimental motor with an aluminum shell rotor- all was good until
the rotor heated up- then the squealing started and, if left, the rotor
would have jammed on the stator. A teflon coating wouldn't have helped.
