Design of multi phase induction motor for electric vehicle application

Abstract

The growing demand for robust, fault-tolerant, and high-performance electric drives in industrial, automotive, and renewable energy applications has intensified interest in multiphase induction machines. Unlike conventional three-phase motors, multiphase systems offer advantages such as reduced torque ripple, enhanced fault tolerance, and higher power density. However, with the increase in phase number and variations in winding configuration, analyzing the magnetic field behavior becomes increasingly complex, particularly in terms of the spatial distribution of magnetomotive force (MMF). This thesis presents a comprehensive investigation into the MMF distribution of multiphase induction motors, with a primary focus on deriving generalized equations for resultant MMF under various winding and connection schemes. The study begins with an introduction to the fundamental operating principles of multiphase induction machines, outlining their advantages, applications, and the challenges involved in their analytical modeling.
