摘要：

This paper studies the effect of permanent magnet shape on the performance and efficiency of coreless axial flux permanent magnet synchronous generator (AFPMSG) for low-speed applications. The objective of this study was to come up with an optimal magnet shape among the studied cases that will lead to the highest value of induced EMF, eventually leading to the better output power of the machine. According to the obtained results, a coreless AFPMSG with a triangular magnet shape has higher induced EMF as compared to trapezoidal or skewed-shaped magnets. Also, a topology with rounded-triangular magnets is analyzed to investigate the effect of the rounded edges on the performance of the generator. 3D-finite element analysis (FEA) is used to analyze and compare the back-EMF and output power of all the investigated coreless AFPMSG topologies. This analysis is carried out using JMAG-Designer 19. 1.
