Abstract:
1. A superconductive electro-magnetic device for use within a direct current motor or generator that includes an armature that rotates when a rotational force is applied thereto and a permanent magnet stator within which the armature rotates, the device comprising: a hollow shielding sleeve located between the armature and the stator, the shielding sleeve having an inner wall and an outer wall, such that a cooling fluid can flow within the shielding sleeve; and a plurality of superconductor plates located between the inner wall and the outer wall of the shielding sleeve and oriented around the armature, and at least one of the following: wherein the hollow shielding sleeve includes an inner core formed of urethane foam, or wherein the superconductor plates are attached to the inner wall of the shielding sleeve and are arranged at intervals of about 45° around the shielding sleeve, or wherein the superconductor plates are attached to the inner wall of the shielding sleeve and bulk fiberglass provides a flat contact surface between the superconductor plates and the shielding sleeve.
