摘　　要：介绍了全自动化刨煤机变频控制系统的总体结构、变频电机的机械和电气结构以及变频系统硬件设计和软件设计。详细研究了变频电机结构及控制系统的功能,研究了速度、电流和力矩对应关系,设计了刨煤机生产过程中的参数监控界面。并解决了原始刨煤机诸多问题,该刨煤机组采用变频电机在矿井下成功应用解决了频繁换向、频繁断链、零速大扭矩软启动问题,实现了电机与控制中心的远程通信及监控,参数设定,故障记录及状态信息查询,主动从动电机任意设置等。This article introduced overall structure of variable frequency control system, the mechanical- electrical structure of variable frequency motor,software design of the system,researched structure of the motor,the functions of the variable frequency control system in detail,and the relationship between motor speed,current and moment; designed the parameter monitoring interface during coal plough operation. Various problems of the original coal plough were solved with the application of variable frequency motor, including frequent inverting, chain breaking, and zero- speed large torque soft start,etc.,realizing remote communication and monitoring of the motor,including parameter setting,failure logging,status information search and altering of master and slave motor.
