Abstract: Apparatus and methods provide for a high specific power electro-dynamo device that utilizes high-temperature superconductors, a dysprosium core, and superconducting coils to provide power. According to various embodiments, a rotor includes a number of rotor arms with a high-temperature superconductor attached to each arm. A stator includes a number of stator arms with stator coils wrapped around each arm. The stator coils may include superconducting wires for providing a charge to the high-temperature superconductors and non-superconducting wires for inducing a voltage from the trapped flux provided by the superconductors during operation in generator mode. The dysprosium core maximizes the magnetic flux saturated by the core while providing additional safety measures during operation. A backup power wheel or permanent magnets positioned in series with the high-temperature superconductors may provide emergency power at non-cryogenic temperatures.

Abstract: The present invention relates to cylindrical rotating electric machines which comprise armature and field coils, with either the field coil or the dual armature being the rotating component. The dual armature is composed of two concentric cylindrical sets of coils with the field coil situated in the gap between the inner and outer armature sections. Relative rotational motion between the field and armature coils can be achieved by having either one be the rotor. By using two armature coil sections, one inside the field coil aperture and the other external to the field coil, the flux linkage between the armature and superconducting field coil can be approximately doubled. This is a more efficient use of the superconductor. The increased flux linkage in the invented technology produces a substantially higher power density than can be obtained with current conventional superconducting machine technology.
