基于四轴飞行器的无刷电机驱动设计

The design of brushless motor drive circuit Based on the four-axis aircraft

详细论述了一种基于单片机为核心的四轴飞行器无刷电机驱动系统,主要包括大功率驱动模块,反向电动势检测模块,PWM输出模块,转速测量模块等四部分。系统可通过I2C通讯接受到主控板发来的信号进行相应的调速,减少控制周期,提高电机的响应频率。

This design expounds a kind of based on MCU four shaft aircraft brushless motor drive system. The system includes high-power driver modules, reverse emf detection module, PWM output module, speed measurement module four parts. The design can receive the signals which are sent by the main board to adjust the the speed by PC communication,and it can reduce the control cycle, improve the frequency response of the motor.
