Abstract :
Multiphase motor drives posses many advantages over the traditional three-phase motor drives such as reducing the amplitude and increasing the frequency of torque pulsation, reducing the stator current per phase without increasing the voltage per phase, lowering the dc link current harmonics and higher reliability. By increasing the number of phases it is also possible to increase the torque per ampere for the same volume and improving the fault tolerance of the drive. The present paper approaches in a comparative manner two winding connection for a 12 stator slots/10 rotor pole permanent magnet synchronous machine. The magnetic filed and developed electromagnetic torque will be analyzed.
