Abstract

It is said that extensive CO2 emissions is a well-known cause for the crucial temperature rise the Earth is experiencing, so all people of the world need to devise a good way to reduce global CO2 emissions. One mean is to utilize some technologies to improve the efficiency of electrical equipment, such as that used for electric- power generation and power machinery. One of the most effective technologies is thought to be the application of high-temperature superconductivity so as to improve energy conversion efficiency based on the zero resistivity of superconductive winding conductors, together with the use of low iron loss magnetic materials. This paper clarifies a theoretical design philosophy for high-efficiency, small-size and lightweight electric rotating machinery, and reports on a survey of the current status of R&D regarding high-temperature superconducting (HTS) electric rotating machinery. In addition, the paper discusses observations regarding the ulterior solvents for successfully and actually manufacturing HTS electric machinery.
