In order to further tap the application potential of brushless DC motor, a brushless DC motor control system based on STM32F407 is designed by studying its structure and working principle. In the control part of the system, the advanced timer in STM32 is used to generate PWM control signals, and Hall signals are used to detect the rotor position of the motor and calculate the speed. Combined with PID algorithm, the robustness and adaptive ability of the control system are improved. In the part of the driver an isolation circuit is added, which can make the system run more stably and improve its antiinterference ability. The debugging platform of the system is built based on LABVIEW, which can observe the running speed of the motor in real time, and make PID parameter tuning more convenient.The system has low cost, high performance and certain engineering application value.
