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。
90% of the existing mine hoist is a winding induction motor hoisting system, control the winding asynchronous motor hardware circuit to the microcontroller as the core, with the software, through the current feedback control to achieve the length of SCR on-time . The DC power supply that enables energy-consuming braking varies with the speed of the motor to save power and embodies the application of computer technology and modern control theory.
