Different design approaches of surface mounted high performance PMSG

In this paper, the standard equations of PMSG have been utilized to develop model generator basic dimensions; where such primary design has been found unable to deliver the exact required rated power. Hence to reach such required rated output power different approaches depend on improved performance and reduced cost criterion are suggested and studied. Three different dimension changing techniques are studied for the highest efficiency and power to volume ratio through linear analysis, and then compared to finite element model (FEM) analysis results. As a conclusion a modified starting design formula is suggested for designing of high performance PMSGs.
