Design and control of multiphase induction motor

Abstract

Many researchers have studied multiphase Induction motor drives and output of their research shows that output Torque of these motors is superior to that of normal three phase Induction motor. Limitations on the power level of semiconductor devices establish a barrier to the increase of converter ratings. In order to get rid of this limitation, multilevel converters have been developed where switches of reduced rating are used to construct high power level converters. Instead of multilevel converters, multi-phase machines are used: By dividing the handled power between multiple phases, generally more than three, high power levels can be achieved even using limited rated power electronic converters. The aim of this research is to implement novel design and development of six phase induction motor. Also control of the same motor is carried out when fed by two, three phase inverters.
