- Abstract
- In this paper, the harmonic characteristics according to the pole/slots combination of an external type synchronous generator for drones were compared. Four models of permanent magnet synchronous generators with fractional slots were selected to analyze and deal with the harmonic content of the no-load back EMF. Through comparison using FEM, one pole number slot combination with the best THD characteristics was selected among the four models, and the response surface method was applied to the selected model to design an optimal design for further harmonic reduction. The reliability of the optimal design result was verified by comparing the optimal design result with the FEM result of the basic model. The performance of the selected model was verified through actual manufacturing and testing, and the reliability of the FEM analysis model was confirmed.
