矿山多驱带式输送机的变频传动应用

摘要

In the long-distance and large-capacity belt conveyor system,traditional multi-motor drive mode is hard to satisfy higher technical requirements.By applying variable frequency drive (VFD),double closed-loop control of speed and torque realized with vector control algorithm,so as to achieve large-torque start-up,speed control and load balance of multiple motors.It possessed obvious advantages and spread significance.%在长距离、大运量带式输送系统中,传统的多电动机驱动方式已难以满足更高的技术要求.而采用变频传动方式,通过矢量控制算法可实现速度和转矩的双闭环,实现带式输送机的低速大转矩启动、调速运行、多驱负荷平衡等功能,应用优点明显,具有推广意义.
