Performance evaluation of asymmetrical multiphase induction motor using Matlab/Simulink

摘要

This paper presents a generalized d-q model of multiphase (six-phase) induction motor in Matlab/Simulink. Further, to observe the advantages of six-phase induction motor over conventional three-phase counterpart, a comparative analysis is performed under similar conditions. It has been observed that the six-phase induction motor have several advantages over conventional three-phase counterpart, such as decreasing the amplitude and increasing the frequency of torque pulsation, reduction in per phase current without increasing the per phase voltage, less settling time, less stator copper loss per phase, higher power handling capability, increased efficiency and more reliable than conventional three-phase induction motor.
