Brushless DC Motor Model with Simulation Analysis

This article examines the significance of brushless DC motor models and their simulation outcomes. While not yet widely adopted in current applications, these models are poised to play an increasingly vital role in future technological developments. Through in-depth study of this model implementation—which typically involves MATLAB/Simulink components for electromagnetic field simulation, PWM control algorithms, and three-phase inverter circuitry—researchers can gain deeper insights into motor operational principles and performance characteristics. Key functions often include hall sensor position detection, commutation logic handling, and torque-speed characteristic modeling. The model enables better optimization opportunities through parameter tuning of winding inductances, back-EMF constants, and switching frequency adjustments. Future researchers are encouraged to reference this work's approach to circuit modeling and control algorithm implementation to advance this field further.
