為了實現對電機的可靠控制，并使其操作簡單，易于控制，運行狀態易于觀察，提高設備自動化程度，設計出一種基于EV3000變頻器，靈活實用的變頻電機調速監控系統。該系統采用艾默生公司生產的EV3000變頻器，通過對電機磁通電流和轉矩電流的解耦控制，實現了對轉矩的快速響應和準確控制，能以很高的控制精度進行寬范圍的調速運行和轉矩控制。同時通過上位機編程軟件設計出功能強大的可視化控制界面，實時顯示電機運行狀態、變頻器參數設置。通過現場試驗，結果證明該系統達到了安全穩定簡單靈活地控制電機的設計目標。

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.
