Development status of rotating machines employing superconducting field windings

Development and Test of a Prototype 100MVA Superconducting Generator

“…The design may be optimized to reduce strain without [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] regard to the conductive penalty. A high degree of accuracy was expected in modeling the conductive heat load to the Demonstrator.…”

“…A high transient gain (13,980 for Design #3) appears to be desirable for voltage regulation and response.…”

Progress in HTS Power Applications in the United States

“…2,6) This led to a 1000 hp motor tested in 2000. This was a 60 Hz 1800 rpm ac synchronous motor with four poles, with HTS field coils manufactured by AMSC using its 1G wire.…”

“…6) The motor used AMSC 1G wire. Then, under an Office of Naval Research contract, AMSC designed and fabricated a 5 MW 230 rpm high torque ship propulsion motor, again using HTS coils fabricated from its 1G wire.…”

“…The success of the 5 MW motor led to a follow-on contract with ONR for a 36.5 MW ship propulsion motor, in collaboration with Northrop Grumman Marine Systems and Ship Systems, Ideal Electric Company, Syntek, Mississippi State University, CAPS, and MSCL LLC. 6) This high torque, 120 rpm motor, also based on 1G wire, is capable of driving the Navy's new generation of destroyer, called DDX. Its weight of 75 tons is a major advantage compared to over 300 tons for conventional alternatives.…”
