Eddy-Current Losses in the Solid Back-Iron of PM Machines for different Concentrated Fractional Pitch Windings

Permanent magnet (PM) machines with concentrated fractional-pitch stator windings are increasingly used because of their cost-effectiveness. In this paper, the eddy-current losses in the solid back-iron of these machines are modeled. This model is applied to calculate the losses in the solid back-ir...
