Abstract
High temperature superconductor (HTS) technology enables a significant reduction in the size and weight of MW-class generators for direct-drive wind turbine systems and reduce the cost of clean energy relative to conventional copper an permanent-magnet-based generators and gearbox. Using MAXWELL, we studied MW class superconducting synchronous machines. By comparison the weight, we concluded that HTS wind turbine with rotor iron is the heaviest and HTS wind turbine without rotor iron and stator teeth is the lightest. By comparison the flux density, HTS wind turbine without rotor iron is the least and HTS wind turbine without rotor iron and stator teeth is the largest. By comparison the cost, HTS wind turbine with rotor iron is the highest and the other two is almost the same. HTS wind turbine without rotor iron and stator teeth is the best type.

Summary
The challenges of future energy demand and the possible global warming due to fossil fuel consumption have boosted the wind turbine generator’s global market. A break-though technology to develop light weight and compact direct-drive wind turbine generators, such as 10 MW, is surely expected in recent years. The optimum weight for a 10 MW direct drive PM generator is greater than 300 metric tons including support structures with an air gap diameter greater than 10 meters [4,5,6] To solve this problem, compact and high-power density wind turbine generators are required. By applying HTS to the wind turbine generators, it is expected to provide the light weight and compact design, since the magnetic field can be higher compared with the conventional generator, so that the iron core can be considerably reduced or removed [7,8].
