Cc/neu Motors

I wonder if a Electromagnet-Electromagnet motor is possible instead of a electromagnet-permanent magnet... That would be sweet if it is possible.

I think that would have to be brushed then - gotta have some way to keep that electromagnetized rotor electrified :P

I want some induction motors for RC use though, that would be cool. means theyd need an a/c speed control.. I wonder what the limitations are and why it hasnt been done? That doesnt use any permenant magnets.

Yes that would imply a brushed motor, until there is a way to send power wirelessly there is no way to have an electromagnet rotor without brushes. I built larger 140mm -280mm diameter brushed motors for 5 years, it was interesting to see and know how they where built, but no money involved in manufacturing

sending power wireless aka Induction ...

you may find that interesting:
