Hi,
I saw few threads here about air-gap in motors, and I wonder what if we ignore mechanical issues and make an "iron-gap" in the motor.
for example: in linear motor(e.g. this cute one: https://www.physicsforums.com/threads/linear-motor-equations.794499/) if we make the tube between the stator and the rotor from iron, it would be more efficient, due to reduce in the magnetic reluctance.
but, it will produce undesirable effects like eddy currents, maybe it will be a Faraday cage.
what do you think? there is a way to overcome those problems?
e.g. cutting a length-wise slot down the tube can mitigate eddy currents
