Patent attributes
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.
