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
