The work presented in this article relates to the design procedure of a permanent magnet synchronous machine, by the use of Output Space Mapping type methods. This type of optimization technique reduces significantly the time necessary to the search for optimal configurations, by the use of a fast modeling of the device to be optimized. At the same time, a second model, slower but more accurate, ensures the validity of the optimal configurations obtained. Two techniques belonging to this family of methods are applied in this study. Their results and performances are compared.
