Abstract
The influence of different grades of electric steel on the performance of direct-drive, ring type, radial flux permanent magnet synchronous generators (PMSG) was investigated. A series of geometrical optimizations of the generator was performed for 9 steel grades. The goal of the optimization was to maximize the annual efficiency, which is calculated on the basis of a yearly wind speed distribution function for a site with an average wind speed of 7 m/s. One may conclude that optimized generators for materials with higher specific loss value consume more active material for the same efficiency value.
