摘要:交流電動(dòng)機(jī)，特別是鼠籠型異步電動(dòng)機(jī)，結(jié)構(gòu)簡(jiǎn)單，成本低，維護(hù)方便，而且堅(jiān)固耐用，慣量小，運(yùn)行可靠，對(duì)環(huán)境要求不高，因此在工農(nóng)業(yè)生產(chǎn)中得到了極廣泛的應(yīng)用。其突出的優(yōu)點(diǎn)是，電機(jī)制造成本低，結(jié)構(gòu)簡(jiǎn)單，維護(hù)容易，可以實(shí)現(xiàn)高壓大功率及高速驅(qū)動(dòng)，適宜在惡劣條件下工作，并能獲得和直流電機(jī)控制系統(tǒng)相媲美或更好的控制性能。 本文主要對(duì)籠型異步電機(jī)進(jìn)行了模型分析，利用坐標(biāo)變換原理得出了其在α β 坐標(biāo)系下的動(dòng)態(tài)數(shù)學(xué)模型，并用simulink 仿真工具對(duì)其進(jìn)行了動(dòng)態(tài)仿真。仿真結(jié)果證明了模型的正確性。 關(guān)鍵詞：MATLAB;籠型異步電機(jī)；仿真
Abstract:AC motor, squirrel cage induction motor, simple structure, low cost, easy maintenance, and rugged, the inertia is small, reliable operation, less demanding on the environment, a very wide range of applications in industrial and agricultural production . Prominent advantage is that the motor manufacturing low-cost, simple structure, easy maintenance, high-voltage high-power and high-speed drive can be achieved, suitable for working in harsh conditions, and DC motor control system is comparable to or better control performance. The This article mainly right the cage type asynchronous motor carried out model analysis of, the use of that the Principle of Coordinate Transformation to drawn the its dynamic mathematical model of under the in the alpha β coordinate system, and use the simulink simulation tool of its carried out the a dynamic simulation. The simulation results prove the validity of the model. Keywords: MATLAB; squirrel cage induction motor; simulation
本文首先分析了異步電機(jī)在現(xiàn)代交流調(diào)速系統(tǒng)中的重要地位，并說明了應(yīng)用傳統(tǒng)的分析方法已不能方便高效地分析復(fù)雜的交流調(diào)速系統(tǒng)，然后簡(jiǎn)單介紹了matlab/simulink 仿真工具，接著分析了異步電機(jī)的物理模型和數(shù)學(xué)模型，最后應(yīng)用matlab/simulink 中的電力系統(tǒng)工具箱建立了異步電機(jī)的系統(tǒng)模型，并在不同負(fù)載下對(duì)其進(jìn)行了動(dòng)態(tài)仿真，取得了比較理想的仿真結(jié)果。證明了模型的準(zhǔn)確性，表明了用simulink 平臺(tái)對(duì)異步電機(jī)進(jìn)行仿真分析是一種方便高效實(shí)用的方法。
