How would superconducting motors/generators work?

  1. Dec 27, 2015 #1
    How can superconductors improve motor/generator's performance?

    A superconductor will expel a magnetic field, how can it generate a Lorentz force in the case of a motor, and a induced EMF in the case of a generator?

    It's makes sense that we can only improve the windings of the electromagnet, to make it superconducting generating higher fields. But what about the rotor of a motor if it's a superconducting... having higher currents would lead to greater torques & speeds,due to the combination of a stronger field & higher current?
