为了实现对电机的可靠控制，并使其操作简单，易于控制，运行状态易于观察，提高设备自动化程度，设计出一种基于EV3000变频器，灵活实用的变频电机调速监控系统。该系统采用艾默生公司生产的EV3000变频器，通过对电机磁通电流和转矩电流的解耦控制，实现了对转矩的快速响应和准确控制，能以很高的控制精度进行宽范围的调速运行和转矩控制。同时通过上位机编程软件设计出功能强大的可视化控制界面，实时显示电机运行状态、变频器参数设置。通过现场试验，结果证明该系统达到了安全稳定简单灵活地控制电机的设计目标。

Abstract:: In order to achieve reliable control of the motor and make it simple operation，easy control，easy to observe the run state，improve equipment automation，a flexible and practical frequency conversion motor speed control system based on EV3000 inverters was designed.The system used the Emerson EV3000 inverter，through the decoupling control of the motor flux current and torque current，achieved fast response and accurate control of torque，it is able to realize a wide range of speed adjustment run and torque control with a high precision. At the same time，through the host computer programming software designed a powerful visual control interface，the motor running status，inverter parameter settings were real time displayed. Through the on-sitetest， this system was proved to be able to achieve safe，stable，simple and flexible control of the motor design goals.
