Mathematical Modeling and Simulation of Multiphase Induction Motor Drives in MATLAB/Simulink Environment

Abstract

This study shows how a simple but flexible model of a multiphase induction motor can
be built in MATLAB/Simulink and used for experiments with different numbers of phases.
Instead of creating separate models for 3-, 6-, and 9-phase systems, one universal structure
was made, where the number of phases can be changed with a single parameter. The
model combines the main electromagnetic and mechanical equations and shows how the
machine reacts to load and voltage changes. Simulations confirmed that when the number
of phases grows, the torque becomes smoother, the slip goes down, and the efficiency
slightly improves. The idea was not to make a complicated control system, but rather a
clear and practical environment that helps to see how multiphase drives behave in real
operation. Such a model can be useful for teaching, research, and for preparing future
optimization studies.
