Six-phase Fractional Slot Concentrated Winding Permanent Magnet Synchronous Motor with Reduced Torque Ripple

A comparative study on a fractional slot concentrated winding permanent magnet synchronous motor with 10 rotor poles and 12 stator coils connected in different arrangements and supplied from a six-phase inverter is presented in this paper. The aim of this investigation is to reduce the torque ripple of the machine by using the appropriate winding connection and power supply unit.
