电机智能测试与控制系统中M-S曲线的测定

The Determining of M-S Curve in Intelligent Testing and Controlling System of Motor

异步电动机的转矩转速曲线是异步电动机的一项重要特性 ,本文提出了一种利用JCZ型智能转矩转速传感器来实时测量电动机转矩和转速的方法 ,并且用PCL711B数据采集卡同步采集电机的端电压来对转矩进行修正。在VB中引用Matrix库函数对数据进行处理 ,最后拟合得到M -S特性曲线。试验结果表明 。

The M S curve of asynchronous motor is very important to motor.This paper presents a new way to test torque and speed of motor real time with JCZ intelligent torque speed sensor.At the same time we sample end voltage of motor with PCL711B.We can draw the M S curve with Matrix in MATLAB.The result shows that this way is feasible.
