    초록(영문)

    The objective of this paper is to derive new configurations of large direct-drive wind generators that would enable significant reduction of the mass and bearing failures of those generators. Scaling up the power of direct-drive wind generators, the structural mass becomes dominant in the total mass of the generators. In wind turbines, bearing failures have been a continuing problem and account for a significant proportion of all failures. It is thus necessary to significantly reduce the structural mass and bearing failures of large direct-drive wind generators in order to make those generators more attractive for industry use. In order to achieve the objective of the paper, the following concepts are discussed in the paper. (1)A Ring-shaped permanent magnet generator without a main shaft and without torque arms (2)Multi-sets of rotor and stator which are easy to manufacture, transport, install and repair
