Abstract: A high temperature superconducting synchronous motor having an inductor topology that increases the air gap flux density in direct relation to motor power density by trapping flux and concentrating it in the air gap to obtain more power in the same volume or smaller volume for the same power, and whose geometry enables the induction motor to be lighter than superconducting motors without the inductor topology, the motor being positioned in a housing, and the motor comprising: a) stator means having an armature winding to provide a stator field; c) rotor means positioned within the stator field and on which is disposed at least two polygon shaped ring or coil means along the same axis to provide separated and spaced apart relationship field solenoids; c) at least four high temperature superconducting plate means disposed in alternating relationship between the ring or coil means to hold the ring or coil means together to trap magnetic field and shape flux lines; and d) cooling means to cool the superconduct

Abstract: A shunt connected superconducting energy management system (SEMS) is provided at a single switched connection between a utility grid and one or more power sensitive loads such as a semiconductor manufacturing plant having power requirements in the range on the order of 2 megawatts (MW) to 200 MW. When a voltage disturbance is sensed in the grid, power control circuitry acts to simultaneously isolate the load and the SEMS from the grid using a single switch which simultaneously provides full back up power to the load instantaneously without voltage transients or disturbances.
