摘要
采用三相异步电动机在αβO坐标系下的数学模型,根据具体定子绕组接线的不对称情况,推导出电机定子端电压的约束条件,编写了一个适合于异步电动机定子对称和不对称运行情况的实用仿真计算程序,通过实例对定子Y形接法三相异步电动机的单相短接制动、两相短接制动和三相短接制动运行过程进行仿真计算,并对仿真结果进行比较分析,得出了一些有用的结论。
According to the mathematical modles of 3-phase asynchronous motor in a
β o coordinates, considering stator terminal voltage constrains of stator symmetrical and asymmetrical conditions, the practical simulation program is written which applies to 3-phase induction motor symmetrical and stator asymmetrical operation cases. The program is applied to simulate stator single phase.two phase and three phase short connected braking operation process of 3-phase asynchronous motor in stator star connection through a real calculation example and simulated results are also comparative studied here.
