Abstract

Due to low-accuracy of traditional magnetic circuit method with single magnetic loop and some approximate empirical formulas in the magnetic circuit calculation of non-salient pole synchronous generator, the distributed magnetic circuit method (DMCM) is put forward and adopted. The comparison of the results among traditional magnetic circuit method, DMCM and finite-element method (FEM) shows the validity and high-accuracy of DMCM. Furthermore, DMCM is more suitable for some special rotor configuration with subsidiary slots, ventilation slots or the slots for q-axis windings.
