Asynchronous Motor and Variable Frequency Speed Regulation System Characteristic Simulation
Abstract: This article for ac asynchronous motor speed made a review introduction, first introduced the ac asynchronous motor speed technology development status, then analyzes the variable frequency speed regulation, finally, it introduces the principle of asynchronous motor speed of several technology. For example: sine pulse width modulation technology (SPWM), Make the frequency conversion technology to realize the popularization. In the variable pressure variable frequency speed regulation system, should meanwhile adjust the speed of the stator voltage and frequency of the power supply, in this case, the basic characteristics of parallel machine movement, slip the same. Using the technology of the frequency converter performance of SPWM more perfect, can get the more widely.
The simulation can operate method have DuoZhong, like MATLAB, Simulink is MATLAB a add-on component, can be used to simulate the linear or nonlinear discrete or continuous, or a combination of the hybrid system, and through a set of graphic animation processing method of users convenient observed the simulation of the entire process. This paper, by using Simulink module base in a variable frequency speed asynchronous motor model.
