Abstract: The motors/generators of the preferred embodiments include a rotating part (rotor) and a stationary part (stator). In the devices disclosed, the primary function of the stator is to provide a high strength background magnetic field in which the rotor rotates. The rotor can be powered with a current that changes direction in concert with the relative change in magnetic field direction of the background field (that is, as the rotor moves from one magnetic pole to the next) in the case of a motor. In the case of a generator, the movement of the rotor generally results in the generation of an alternating voltage and current.

Abstract: An electromagnetic device is presented. The device includes a stator, a gap comprising multiple gap regions, and a rotor arranged in the gap to move relative to the stator. One of the stator and the rotor comprises a conductor array having one or more conductors each configured to carry current in a respective current flow direction. The other of the stator and the rotor comprises a flux directing assembly having multiple flux directing sections, each arranged adjacent to at least one other flux directing section and each configured to facilitate a circulating magnetic flux path about the respective flux directing section. Each pair of adjacent flux directing sections are arranged about a common gap region of the multiple gap regions and configured to direct at least part of the respective circulating magnetic flux paths across the common gap region in a substantially similar flux direction substantially perpendicular to the current flow direction.

Abstract: A number of configurations of a high speed electromagnetic turbine (1300) are discussed. The turbine (1300) includes a housing (1301) includes at least superconducting coil (1307) for the generation of a magnetic field, the coil being retained within a cryogenic envelope of a cryogenic body (1306). The turbine (1300) includes also includes rotor assembly including one or more rotors (13091), (13092), (13093), (13094), (13095) and (13096) positioned on shaft (1310). The rotor being received within the bore (1308) formed between the interior walls of the body (1306) such that it is immersed in the magnetic field. As the current is passed through the rotor assembly the induced force due to the interaction of the current with the magnetic is translated into a torque on the shaft (1310).

Abstract: Various configurations of an electrometric turbine are discussed. In one possible arrangement the turbine is a radial drum type turbine and includes a pair of opposing magnetic assemblies with drum positioned therebetween. Each of the magnetic assemblies includes a pair of coils an outer coil and an inner coil. The coils are arranged concentrically about the axis of rotation of the drum, i.e. the coils are co-axial with the rotational axis of the drum. The drum includes at least one conductive element coupled to current transfer mechanisms which pass current across the drum. As current is passed across the conductive layer of the drum torque is generated on the drum. The torque is transferred to the output shaft which passes through the drum and magnetic elements.
