摘要: 针对交流变频调速性能好、调速范围大、节电效果明显和变频器体积小便于安装的优点,文中对交流调速的发展现状及理论依据进行了分析和研究,在已有技术的基础上,提出了基于LabVIEW软件设计上位机界面,通过使用串口通讯的方式来控制下位机西门子mm440变频器,再由变频器去控制三相异步电机YZA5632S,以实现异步电机的变频调速的设计方案。该方案可以有效地控制变频器,能实时读取电机转速,使交流异步电机的调速更加简便。

Abstract: According to the advantages of AC variable frequency speed regulation,such as good speed regulation performance,large speed regulation range,obvious power saving effect,and convenient fixing due to small size of the inverter,the development status and theoretical basis of AC speed regulation are analyzed and studied in this paper.On the basis of existing technology,aplan designing the upper computer interface based on LabVIEW is designed by using serial communication to control the lower computer Siemens mm440transducer,and then using the transducer to control the three-phase asynchronous motor YZA5632Sto realize asynchronous motor’s frequency control.In this design,the transducer can be controlled effectively and the real-time asynchronous motor’s rotate speed can be read,which makes it easier to adjust the speed of asynchronous motor.
