Brushless DC Motor Simulation with Detailed Implementation

In this Brushless DC Motor Simulation project, we provide more detailed documentation and simulation programs than the original version, including the construction principles of each module with specific code implementation approaches. First, we introduce the fundamental principles of brushless DC motors and explain why they offer superior performance compared to traditional brushed motors. The simulation program construction process is thoroughly explained, covering circuit modeling techniques using Simulink blocks, parameter configuration methods through MATLAB scripts, and simulation execution procedures. Additionally, we analyze the functions and interrelationships between different modules (such as the inverter bridge, Hall sensor processing, and PWM control modules) to help readers better understand the complete simulation workflow. The implementation includes key algorithms like trapezoidal commutation control and six-step drive methodology. Finally, we provide troubleshooting guidelines for common simulation issues and practical tips for optimizing motor performance parameters. This project aims to assist in both learning and practical application of brushless DC motor simulations through hands-on code examples and systematic explanations.
