Özet

In this study, the offset points which locate at the pole arc of the designed 1 kW direct-drive permanent magnet synchronous generator (PMSG) have been changed based on parametric approach, and a performance rise for the designed generator has been observed by changing offset parameters. In order to obtain efficient physical sizes and electrical values of the designed generator, the pole arc offset points have been taken forward gradually by using finite element methods. The effects of different offset points on the generators performance have been simulated and interpreted graphically. It has been shown that changing pole arc offset sizes has decreased harmonics distortion and magnet weight in designing 1 kW PM generator. As a result, the 1 kW PM generator has been obtained with high efficiency, less harmonic distortions at sinusoidal wave and less PM weight at whole generator weight.
