... Analyzing the results, it is possible to confirm The difference between the real MMF, given by NI, and that the maximum reluctance is achieved at unaligned the estimated MMFestimation is used to choose new magnetic positions, while minimal reluctance is obtained with primary flux estimation. This iterative process is repeated until the poles aligned with ...
