Analysis and Modelling of Fractional-Slot Concentrated-Wound Interior Permanent Magnet Machines
… (IPM) machines and establishes a basis for their magnetic and electrical analysis. In the state of the art methods for analyzing such machines, the non-homogeneous magnetic saturation and the non-linear B-H curve of the rotor iron are not considered. Moreover, the effect of the FSCW stator on the …
