Research on transient torque measuring system of switched reluctance motor based on LabVIEW

根据开关磁阻电机的特性和瞬态转矩的计算原理,对开关磁阻电机的瞬态转矩测量进行了研究;并利用虚拟仪器技术和PCI-6250多功能数据采集卡开发了一个开关磁阻电机瞬态转矩测试系统.该系统根据数据采集及其相关的计算原理,结合LabVIEW以及数据配置程序MAX,通过PCI板卡对开关磁阻电机进行数据采集,可对电机的转矩、转速、相电压和相电流等瞬态特性进行瞬时测量,并可在终端客户机上进行同步波形及数值的显示,同时可由用户对实时测量的数据进行保存.

On the basis of the characteristics of the switched reluctance motor and the calculation principles of transient torque, the measurement of the transient torque of the switched reluctance motor is investigated. Meanwhile, a measuring system of the transient torque of the switched reluctance motor is developed using the virtual instrument technology and the multifunctional data acquisition card PCI-6250. Based on the data acquisition as well as the related calculation principles, combined with LabVIEW and data configuration program MAX, and by means of the PCI card to acquise the data of the switched reluctance motor, the transient characteristics of the motor, such as torque, rotate speed, phase voltage, phase current can be instantaneously measured by the system. In addition, the synchronous waveform and numerical value can be displayed and relatively configured on the terminal client. Meanwhile the data of real-time measurement can be saved by the users.
