Status of HTS Motor Development in Korea

This work is development activities of HTS motor at DOOSAN heavy industry and Korea Electrotechnology Research Institute in Korea, and is sponsored by DAPAS program which is supported by Korean government. The final aim of the project is realization of HTS motor in the field of industry such as large driving pumps, fans and compressors for utility and industrial environments. At present time, 1 MW HTS motor is developed for the purpose to fully represent the design and manufacturing issues for the larger capacity machine. The machine is 2 pole and 3,600 rpm, and all of the components are completely manufactured. Preliminary performance test of this machine was already finished, and is ready for long run reliability test. This paper summarizes the status of 1 MW HTS motor development, such as design, construction, and experimental test. As a next step target, ship propulsion motor is considered, so that middle class such capacity as 5 MW, and large class such capacity as 20 MW HTS motor are conceptually designed. The outline and conceptual design results for homopolar and air-core type superconducting motor which apply to low-speed high power pod propulsion application are discussed i n this paper.
