Abstract :
A high-efficiency super drive system (HESDS) for next-generation coastal ships, which has very high efficiency compared with the conventional system, was proposed here. Fundamental electric designs of 660 and 1000 [kW], 190 [1/min] HTSM (high-temperature Superconducting synchronous motors) for 749GT commercialized containerships with HESDS were carried out using a developed design program. As a result, the basic machine performances along with these sizes were clarified and conceptual structure of 660 kW HTSM was shown.
