Abstract

This paper presents a generalized model of multi-phase induction motor drive using matlab/simulink. Multiphase induction motor (more than three phases) drives possess several advantages over conventional three-phase drives, such as lower torque pulsation, higher torque density, fault tolerance, stability, high efficiency and lower current ripple. When the number of phases increases, it is also possible to increase the power /torque per rms ampere for the same volume machine. In this paper, a generalized dq-axis model is developed in Matlab/Simulink for a multi-phase induction motor. The simulation results are presented for 5, 6, 7, 9 and 12 phase induction motor under varying load conditions. Transient response of the multi-phase induction motors are given for different number of phases.
