Comparative Performance Analysis of Optimized PWM VSI-Driven Tri- and Pentaphase Motors

This study conducts an exhaustive comparative analysis of three-phase and five-phase induction motors, focusing on their performance when driven by a Sinusoidal Pulse Width Modulation Voltage Source Inverter (SPWM VSI). The objective is to elucidate the inherent strengths and limitations of each type of motor, using mathematical models grounded in electromagnetic principles. These models encompass critical parameters such as stator and rotor windings, magnetic field distribution, torque generation, and overall performance metrics. Through SPWM VSI, the paper examines aspects like total harmonic distortion (THD), waveform quality, and motor efficiency. A multi-faceted comparison is performed, emphasizing key performance indicators like torque production, speed variability, and harmonic content. The study also investigates the influence of additional phases in the five-phase motor on these performance parameters. The results obtained from the MATLAB/Simulink simulations are presented to support the comparative analysis. Overall, the findings offer nuanced insights into the suitability of tri- and pentaphase motors for diverse industrial applications, given their respective advantages and drawbacks.
