抄録

The research and development conducted regarding fully superconducting motors for liquid-hydrogen transfer pumps using MgB2 monofilamentary wires are gathered into this paper. Synchronous rotation without slip can be realized using squirrelcage-type rotor windings composed of quasi-superconducting loops soldered between MgB2 wires, thereby enabling superconducting motors with low loss and high efficiency to be achieved. The use of MgB2 wires for stator windings also enables the primary winding loss to be reduced drastically compared to conventional copper winding. The transfer of liquid hydrogen from a metal cryostat containing the fabricated MgB2 motor to a glass Dewar vessel for visual monitoring is demonstrated successfully.<tt> </tt>
