Control of Designed Developed Six Phase Induction Motor

Amongst many types of electrical motors, induction motors still enjoy the same popularity as they did a century ago. Several factors which include robustness, low cost and low maintenance have made them popular for industrial applications when compared to dc and other ac motors. Another aspect in induction motor drives which has been researched recently is the use of mult iphase induction motors where the number of stator phases is more than three. Here, a multi-phase system is a system with more than three stator phases. For machine drive applications, mult iphase induction motor could potentially meet the demand for h igh power electric drive systems which are both rugged and energy efficient. High phase number d rives possess several advantages over conventional three phase drives such as reducing the amplitude and increasing the frequency of torque pulsation, reducing rotor harmonic currents, reducing the current per phase without increasing the voltage per phase, lowering the dc link current harmonics, higher reliability and increased power. Multiphase induction motors have found many applications such as electric/hybrid vehicles, aerospace applications, ship propulsion etc.
