Reduction of Eddy-Current Losses in Fractional-Slot Concentrated-Winding Synchronous PM Machines

This paper presents the results of an investigation focused on the rotor eddy-current losses of a permanent magnet (PM) synchronous machine that is equipped with fractional-slot concentrated windings (FSCWs). Major spatial harmonics that induce the most significant rotor eddy-current losses are iden...
