The SEAC motor described in this paper utilizes superconductive windings both for the stator and the rotor and operates the same as a conventional motor by supplying power to the stator. The rotor of a simple SEAC motor has a small and a large winding and two switches. The axes of the two rotors winding are normal to each other. The rotor is initially stationary and the windings are exposed to the rotating stator field. Flux pumping is employed to charge the rotor windings. As the field rotates by 180 degrees from being parallel to the axis of the small winding of the rotor, a switch which is connected in series with the windings, is designed to automatically open allowing the magnetic flux to penetrate the winding.
