2、小等優(yōu)點，從而被廣泛應用于家用電器，電動縫紉機，食品加工機以及各種電動工具，小型電機設備中，因此，研究三相異步電動機的建模與仿真。三 . 實驗步驟1. 選擇模塊首先建立一個新的simulink 模型窗口，然后根據(jù)系統(tǒng)的描述選擇合適的模塊添加至模型窗口中。建立模型所需模塊如下：1 ) 選擇 simPowerSystems 模塊庫的Machines 子模塊庫下的Asynchronous Machine SIUnits 模塊作為交流異步電機。2 )選擇simPowerSystems 模塊庫的Electrical Sources 子模塊庫下的Three-PhaseProgrammable Voltag

3、e Source 模塊作為三相交流電源。3 )選擇simPowerSystems 模塊庫的Three-Phase Library 子模塊庫下的Three-PhaseSeries RLC Load模塊作為串聯(lián) RLC負載。4 )選擇 simPowerSystems 模塊庫的Elements 子模塊庫下的Three-Phase Breaker 模塊作為三相斷路器，Ground 模塊作為接地。5 )選擇 SimPowerSystems 模塊庫的Measurements 子模塊庫下的Voltage Measurement模塊作為電壓測量。6 )選擇 Sources 模塊庫下的Constant 模塊作為

4、負載輸入。7 )選擇 Signals Rounting 模塊庫下的Bus Selector 模塊作為直流電動機輸出信號選擇器。8 ) 選才S Sinks模塊庫下的 Scope模塊。9 )選擇 SimPowerSystems 模塊庫的Measurements 子模塊庫下的Three-phase V-IMeasurements 用于創(chuàng)建子系統(tǒng)。10 搭建模塊將所需模塊放置合適位置，再將模塊從輸入端至輸出端進行相連，搭建完的串電阻起動simulink 模型如圖1 所示圖1三相異步電動機 Simulinks仿真模型11 模塊參數(shù)設置(1) Asynchronous Machine SI Units 模
