Abstract

High Temperature Superconducting (HTS) synchronous motors consist mainly of rotational (HTS coil) and stationery (copper coil) parts. The HTS coil running at a synchronous speed is not influenced by the magnetic field generated by the stator coil but is affected considerably at the initial or transient operation. Therefore, computational analysis to determine the optimal design of the damper is an important factor in protecting the field coil of a HTS synchronous motor. This paper presents the optimal design parameters of the damper for a 5 MW HTS synchronous motor using the computational analysis of the transient characteristics of the stator current, which is proportional to the alternating magnetic field of the stator coil.
