Design And Implementation Of The Double-Sided Axial-Flux Pmsg With Slotted Stator By Using Sizing Equation And Fea Software
Axial-flux permanent magnet (AFPM) machines have become an important subject of study because of the development of neodymium magnets over the past 20 years. Axial-flux machines have high power density and high torque. Axial-flux permanent magnet machines have many unique features. For being permanent magnet, they usually are more efficient, as field excitation losses are eliminated, reducing rotor losses significantly. Machine efficiency is thus greatly improved, and higher power density achieved. Axial-flux construction has less core material, so, high torque-to-weight ratio. The noise and vibration they produce are less than those of conventional machines. Their air gaps are planar and easily adjustable. The aim of this paper is to perform more accurate design calculation and analysis of an axial-flux permanent magnet synchronous generator, double-sided with external rotors and internal slotted stator. The evaluation is based on theoretical analysis by means of sizing equations and confirmed by finite-element analysis. Therefore, the AFPMSG topology considered in this paper is a three-phase double-rotor single-stator topology with 16 pole-pairs, 2kW rated power and 188 rpm rated speed. The performance of double-sided APMSG for slotted stator design is analyzed with finite element analysis (FEA).
