Aren't mass produced electric motors made by machine?
A switched reluctance motor could get interesting. No magnets - just a rotor shaped to produce torque as the stator coils switch on and off. Just need access to a powerful CNC laser cutter to make all the stator and rotor pieces...
Maybe even use thin copper tubing painted with a special insulation paint as the windings. Then just pump oil through them to keep it cool.
