Permanent Magnet Motor Modeling and Simulation in Simulink

This article provides an in-depth exploration of Simulink modeling for permanent magnet motors. We will systematically demonstrate how to build accurate motor models through step-by-step procedures, including parameter configuration techniques using MATLAB's workspace variables and model validation methods through comparison with experimental data. The discussion covers different types of permanent magnet motors (such as surface-mounted and interior permanent magnet designs) and explains how to implement corresponding modeling approaches using Simulink's electrical component libraries. Furthermore, we will detail how to utilize Simulink models for motor control system development - implementing field-oriented control algorithms using PI controllers and PWM generation blocks, and performing dynamic simulations to analyze torque-speed characteristics. The article also explains how to use these models to study motor performance metrics like efficiency maps and thermal behavior through parameter sweeping techniques. By studying this material, readers will gain comprehensive knowledge of permanent magnet motor modeling that can significantly benefit both industrial applications and research projects.
