Brushless direct current motor speed detector based on hall element and control method thereof

Abstract

本发明涉及一种基于霍尔元件的无刷直流电机测速装置及其控制方法,包括:霍尔信号处理单元接收无刷直流电机的霍尔元件输入的霍尔信号进行滤波整形后输出至单片机处理单元;单片机处理单元对霍尔信号处理单元输入的信号进行核心算法处理后通过对外接口单元输出速度信息;对外接口单元具有5V和3.3V逻辑电平对外输出串行接口;方法包括:进行设备初始化;当有串口中断请求时,执行串口中断服务程序;当有定时器请求时执行定时器中断服务程序;如有结束命令则结束循环控制过程。本发明将利用霍尔元件测速的功能提炼出来,专门的测速模块,对外通过串口传递信息,便于系统的集成,较好的解决了测速波动的问题,具备故障报告机制,通用性较好
