摘　　要：现有的矿井提升机90%是绕线异步电机提升系统,控制绕线异步电机的硬件电路,以单片机为核心,在软件的配合下,通过电流反馈控制,实现可控硅导通时间的长短。使能耗制动的直流电源随电机转速大小变化,节约电能,体现了计算机技术和现代控制理论的应用。Most of the existing mine hoist 90% is winding asynchronous motor hoisting system. The control hardware circuit winding asynchronous motor, single _chip microcomputer as the core, through the support of software, By current feedback control, control thyristor conduction time. Motor speed variation, the DC power supply energy consumption braking on the changes of size, Save electricity, reflect the application of the computer technology and modern control theory.
