Status of the 1000 HP HTS motor development

Abstract

Progress has been made in the development of high efficiency HTS motors with the aid of Department of Energy funding under the Superconductivity Partnership Initiative. This effort includes the fabrication and testing of synchronous motors with HTS field windings. The objectives of this development effort include saving half the losses of conventional motors in a package with half the volume. In Phase I of the present program, a 125 HP synchronous motor with an HTS field winding was designed and tested to levels in excess of 200 HP. This paper summarizes the status of a 1000 HP motor development which is part of a Phase II effort. The program elements to be reviewed include the overall design characteristics of the motor, the status of the field coils and refrigeration system, and a description of other components of the 1000 HP motor system. The 1000 HP motor fully represents the design issues to be addressed in the 5000 HP motor also to be developed in Phase II.
