摘要： A portable power system has a turbine engine generating mechanical energy. A homopolar electrical machine receives this energy. The homopolar electrical machine has a single stationary superconducting field coil configured to create a magnetic field. A homopolar rotor is configured to rotate within the magnetic field such that a rotating magnetic field is created in a stationary winding by interaction of the rotating permeance wave produced by the homopolar rotor and the magnetic field produced by the single stationary field coil. The homopolar electrical machine is configured as a generator and produces electrical power for the portable power system.

摘要： A rotating machine comprising a superconductive coil and a temperature sensor operable to provide a signal representative of superconductive coil temperature. The rotating machine may comprise a control system communicatively coupled to the temperature sensor. The control system may be operable to reduce electric current in the superconductive coil when a signal representative of a defined superconducting coil temperature is received from the temperature sensor.

摘要： A pole piece for use in an open magnet includes a magnetizable body of generally cylindrical shape and made of a ferromagnetic material with a plurality of concentrically-arranged, annular-shaped, radially spaced-apart grooves formed in the inner surface of the pole piece. A plurality of annular-shaped, electrically conductive coils are disposed within the grooves. The pole piece with recessed shielding coils is situated within a cryogenic vessel to maintain the pole pieces at a uniform cryogenic temperature. The result is an open magnet structure which provides a highly uniform, high field, open field of view for MRI with a well-contained stray field.
