Abstract

This paper presents the results of the fabrication and preliminary charging test of second-generation higherature superconducting (2G HTS) coils for the rotor field winding of a 1-kW-class HTS rotating machine (HTSRM). This machine technically employs an HTS contactless rotary excitation device (CRED), which is the so-called rotary flux pump, to charge the HTS field windings using a noncontact excitation method. In this study, the major components of the 1-kW-class HTSRM, such as the 2G HTS coils for the rotor field pole of the rotating machine, HTS strands with a toroidal head for the rotary part of CRED, and stationary part of CRED, were fabricated and assembled. Then, the charging performance of the field operating current was tested in preliminary experiments. In particular, to confirm the technical feasibility of CRED on application to the 1-kW-class HTSRM, the HTS field coils were charged under various operating conditions of the HTS CRED in a stationary flux-pump mode.
