Abstract: TThis paper covers the design and characteristics of 2MW high temperature superconducting (HTS) wind generators according to geared and gearless types. The 2MW HTS generator is designed based on the electromagnetic analysis results obtained by 3D finite element method. The total length, volume and weight of the HTS wires of the designed 2MW HTS generator were compared. As a result, the HTS wire length of a geared HTS generator is about 95.2% less than that of a gearless HTS generator. Also, the weight of a geared HTS generator excluding the gearbox is 90.35% lighter than a gearless HTS generator. However, considering the mechanical reliability and weight of the gearbox used with the geared generator, as well as the structural simplicity of the gearless HTS wind generator, a gearless generator can be advantageous. The analysis results can be effectively used to design HTS wind generators with or without gearbox.
