Abstract: A system to convert electrical power to torque is disclosed where the system includes one or more motor controllers, each motor controller adapted and configured to receive power input commands and to receive high-voltage, direct-current (HVDC) input power and convert the HVDC input power to multiphase high-voltage, alternating-current (HVAC) output power, wherein each motor controller varies its respective multiphase HVAC output power in response to the power input commands received; and an electric motor assembly having a main shaft for supplying torque, the electric motor configured and adapted to receive input power as multiphase HVAC from the one or more motor controllers to rotate the main shaft. The system in an embodiment is configured as a propulsion system, wherein the shaft of the electric motor assembly is configured to supply torque to a propulsor of an aircraft.

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.

Abstract: Various configurations of an electrometric turbine are discussed. In one possible arrangement the turbine is a radial drum type turbine 1800 and includes a pair of opposing magnetic assemblies 18011, 18012 with drum 1802 positioned therebetween. Each of the magnetic assemblies 18011, 18012 includes a pair of coils an outer coil 18031 and an inner coil 18032. The coils are arranged concentrically about the axis of rotation of the drum 1802, i.e. the coils 18031, 18032 are co-axial with the rotational axis of the drum 1802. The drum 1802 includes at least one conductive element 1805 coupled to current transfer mechanisms 1806 which pass current across the drum 1802. As current is passed across the conductive layer 1805 of the drum 1802 torque is generated on the drum 1802. The torque is transferred to the output shaft 1807 which passes through the drum and magnetic elements.
