摘要
与交流电动机相比,直流电动机结构复杂,成本高,运行维护困难。但是直流电动机具有良好的调速性能、较大的起动转矩和过载能力强等许多优点,因此在很多行业中应用。在本文中,设计一种基于凌阳单片机的直流双闭环调速系统,并对系统的硬件及软件部分作了具体的介绍及论述。该系统包括转速给定、转速显示、转速检测、电压电流检测和转速控制等。该调速系统容易实现,成本低廉,具有很好的实用价值。
Compared with AC electromotor,DC electromotor is more complex,the cost is expensive and the maintenance is difficult.But,DC motor has much merit,such as：batter speed performance,bigger starting torque and stronger overload capacity,etc.Therefore,it is applied widely in many industries.In this paper,a kind of double closed loop DC motor speed control system is designed based on the SPMC75F2413.And introduced and discussed the hardware and software designed specifically.This instrument consists of rotation setting,display and detection,current sensing,and so on.It can be showed that this system have the advantages of easy-imlement,lowercost and better use value.
