Performance of Fractional-Slot Winding PM Machines due to Un

Abstract PM machines in which slot number and pole number combination differs by one have to be configured with asymmetric winding pattern in order to maximize

For the fractional-slot concentrated windings, the winding factor is redefined independently of the number of poles and formulated through the
