This paper present the development of prototype six phase induction motor using mat lab software and proved that the torque of this motor is superior than that of the three phase induction motor. Three phase induction motors are standard because it’s cost, robustness, reliability and maintenance free operation. To improve the system performance facing the limits on power ratings of the power supplies and semiconductors motivates the phase numbers more than the conventional three phases and machine output power can be divided into two or more solid state inverters of the same power limits. More phases bring to control additional degree of freedom for the further improvements of the drive system
