Production and Test of a REBCO Superconducting Synchronous Motor

Overview of superconductivity in Japan – Strategy road map and R&D status

“…Configuration of the eight pole 7.5 kW machine with YBCO field windings being developed in this project is shown in Fig. 11 [7]. The field windings are cooled by circulation of pressurized low temperature helium gas.…”

Review of progress in electromechanical properties of REBCO coated conductors for electric device applications

“…These superior properties lead to the expectations of CC tapes to be adopted in magnets, SMES, rotating machines, cables and even wide range of applications. With the achievement of a km length CC tapes with higher critical current density, J c , coils for motors, accelerators, high field magnets, and other superconducting devices are already being tested and studied [1][2][3][4][5][6][7]. For such applications, in which coil is one of the major component technology, the electromechanical property (EMP) evaluation is one of the foremost things to do to ensure its performance during fabrication and operation.…”

Mechanical and electro-mechanical analysis in differently stabilized GdBCO coated conductor tapes with stainless steel substrate

“…REBCO coated conductor (CC) tapes have been recently used in practical applications such as power cables, rotating machines, coil windings, and magnets [1][2][3][4][5][6] since these CC tapes have shown superior superconducting properties at external magnetic fields and have good mechanical strength [7][8][9]. Among REBCO CC tapes, GdBCO CC tape showed better electrical properties under external magnetic fields as compared to those of YBCO or SmBCO CC tapes [10][11][12].…”
