Abstract

The high speed permanent-magnet synchronous generator is an important component of micro gas turbine. One of the major problems in micro turbine generator is an increase in iron loss with increasing rotational speed. In order to minimize the iron loss, PNF-Core (20PNF1500, posco electrical steel) is used for stator core. The core has good magnetic properties in high frequency where eddy current loss extremely increase. This paper presents a no-load iron loss calculated by magnetic circuit model and core losses data. To verify the analytical loss calculation a 2-D finite element analysis and a back-to-back test have been performed.
