A direct-drive generator for offshore multi-megawatt class wind turbine has attracted interest because of its higher energy density in comparison with a gear train type generator. The direct-drive generator in the ways of magnetic flux direction are divided into AFPM(Axial Flux Permanent Magnet)- and RFPM(Radial Flux Permanent Magnet)-type machine. The AFPM-type machine is highly efficient in generating electricity due to its structural feature such as narrow width in comparison with the RFPM-type machine. If the AFPM-type machine is applied, an increase of electric power production through multi-stage in axial direction is easily achieved. On the other hand, the RFPM-type machine can be applied to a geometric feature of wide width. In this study, a hybrid two-stage direct-drive generator for 6.2MW was proposed, in which the two-stage AFPM-type machine for 5MW was composed of each topology model for 2.5MW with hollow shape of the rotor with annular disc, the stator and the main shaft mounted on coupled slew bearings. In addition, the RFPM-type machine with a capacity of 1.2MW was inserted to the hollow shape of the rotor.(This work was supported by NRF grant funded by MEST, No. 2017R1A2B4005405)
