Investigation of Winding Circuit Effect on Characteristics of Permanent Magnet Synchronous Machines with Fractional Slot Concentrated Winding
Star-connected and delta-connected circuits of fractional slot concentrated winding in permanent magnets synchronous machines (SMPM) are described in the paper. Advantages and drawbacks of these winding circuit types are shown. Investigation results on the characteristics degradation in the machines with fractional slot concentrated windings owing to delta-connected circuit are presented.
