Recently, gearless type generators, which have very low rotation speed and high torque, have been preferred over the geared type due to the problem of the gearbox reliability. In particular, a high-temperature superconducting generator is promising for wind power applications because of its advantages of weight, size, and efficiency. In this paper, a 10-MW class superconducting wind power generator is designed using Y-Ba-Cu-O and Bi-Sr-Ca-Cu-O wires, and the weight of the superconducting generator is estimated. The finite elements method is used to analyze the magnetic field distribution, and the 3-D CAD program is used to calculate the weight of the super-conducting synchronous generator. The designed 10-MW class superconducting generator is analyzed and discussed considering the proper weight. The designed 10-MW superconducting generator will be effectively utilized in the construction of the 10-MW class wind power generation system.
