Abstract
A motor/generator that is operable in an inductive mode during a startup phase and in a synchronous mode thereafter. Superconductor material is included in either the stator or the rotator and a magnetic field generator is included in the other of these two members. Induced fields in a torque-shield provide coupling between the stator and the rotor during the startup phase and then a trapped field in the superconductor provides coupling between the stator and the rotor thereafter.
