基于GD32F407的国产化电机驱动系统设计OACSTPCD

In the paper,a domestic motor drive system is designed based on GD32F407.The system is an important part of the application transfer device of positioning directional navigation system and needs to be used with a turntable.Its main function is to generate excita-tion signals of angle position sensors,namely rotating transformers.The dedicated modulation and demodulation position information chip is used to accurately judge the rotating position of the motor,the single-chip microcomputer is used to realize signal processing,modula-tion and demodulation position information processing,and the motor driver chip WSA67 is used to drive the motor to complete direc-tional quantitative rotation of the turntable,and the stable speed control of the turntable is realized in the process of rotation.At the same time,the data transmission with the turntable system is completed through the isolated serial interface.
