摘要： An elongated composite material (60) for current limiting applications is disclosed comprising one more high-temperature superconductor filaments (52) and a second electrically conductive matrix (54) member, which may include a sheath of high bulk resistivity surrounding the filament. The sheat (54) is preferably made of Ag doped with resistivity enhacing metals like Ga, In, Sn, Zn, Cd, Sb. To improve the thermal response a thermal stabilizing element (58), preferably stainless steel or Cu alloy, is bonded to the matrix. The current limiter exhibits dissipation in the range of 0.05-0.5 V/cm at currents of 3-10 times the operating current, thereby minimizing fault currents and improving recovery capability.

摘要： A method of maintaining a desired level of sub-transient reactance in a superconducting machine includes specifying a desired level of sub-transient reactance. A stator assembly is produced that includes at least one stator coil assembly having a first predefined length. A rotor assembly is produced that is configured to rotate within the stator assembly. An asynchronous field filtering shield, having a second predefined length that is less than the first predefined length, is positioned between the stator assembly and the rotor assembly. The desired level of sub-transient reactance is achieved by adjusting either the first predefined length or the second predefined length.

摘要： A cooling device for cooling a stator (200) of the type having windings (1), electrically insulated from each other including a cooling member (14, 17, 101, 102), thermally coupled to an external surface of the windings. The cooling member has at least one passage extending through the member to receive a coolant from an external source. Because the passage for receiving the coolant is insulated from the high voltage stator conductors, water having ions (e.g., fresh water) can be used as the coolant for cooling the stator. Allowing the use of fresh water offers tremendous advantages in settings where deionized water is not readily available and eliminates the cost of a water deionization system.

摘要： An exciter (10) includes a concentrically laminated rotary disk (25) with an alternative current (AC) windings (30), and a stationary disk (35) with direct current (DC) excitation windings (40) and a plurality of DC excitation poles (45). The stationary disk (35) is spaced from the rotary laminated disk (25) to form a gap therebetween. Upon rotation of the laminated disk (25), a DC current applied to the DC excitation poles (45) produces an AC current in the AC windings (30). The AC current passes through a rotating rectifier (20) to produce DC current, which supplies the generator or motor field. The stationary disk (25) also includes pilot AC windings (50). The DC excitation poles are on a first face of the stationary disk and the AC windings are on the second face of the stationary disk. A rectifier (305) is coupled between the pilot AC windings and the DC excitation windings of the stationary disk. A pilot disk (60) with permanent magnets (65) is spaced from the stationary disk to form a gap therebetween. Upon rotation of the pilot disk (60), an AC current is created in the pilot AC windings (50) of the stationary disk (35).

摘要： A superconducting motor (1) which operates in a synchronous mode of operation, can also be operated in an induction mode in the event that the superconducting components (30) of the motor (1) lose their superconducting properties (e.g., due to cooling system failure). The superconducting electric motor (1) includes a rotor assembly (5) having at least one superconducting winding (30) which, in operation, generates a flux path within the rotor assembly (5), and a support member (20) which supports the at least one superconducting windings (30). The rotor assembly (5) is configured to operate in a synchronous mode of operation at temperatures when the superconducting winding (5) exhibits superconducting characteristics.

摘要： A superconducting winding includes a pair of superconducting winding sections electrically connected at a node and bypass circuitry connected between the node and electrical ground and configured to allow current to flow to electrical ground when a voltage across the superconducting winding exceeds a predetermined threshold voltage. In certain embodiments, the bypass circuitry includes a switching device (e.g., zener diode) having an open position and a closed position, the switch in the closed position to allow current flow when the voltage across the superconducting winding exceeds the predetermined threshold voltage.
