Summary

The magnetic-field generators of electromagnetic vibration apparatus for Maglev ground coils operate in a persistent current mode for periods of time. In addition, almost of the time, the current lead of the generator acts as a route for heat leak to the inside; therefore, the authors have developed low-heat-load current lead equipment. This equipment consists of a high-temperature superconductor (HTS) lead and the low-duty metallic lead allows the generator to magnetize and demagnetize without a gas cooling system. This realizes labour savings and reliable operations for magnetizing and demagnetizing the generator. This result is also valuable for further improving the superconducting magnet of the Maglev.
