Since 1988, the development of a practical superconducting generator has been carried out in Japan. The authors have developed a rotor with a highly stabilized superconducting field winding and a stator with an air gap winding composed of double transposed copper coils. A series of tests were completed at the end of 1997. The output of 78.8MW was recorded, which was the highest value obtained worldwide. The development of the generator and the test results are described.
