EMS型磁浮列车直线发电机电动势的粗略估算

提出一种简单易行的估算直线发电机电动势的方法。首先通过ANSYS软件对直线发电机进行建模,并由分析得出列车的实际运行时,模块上发电线圈的实际磁力线变化发电情况类似于某一时刻模块上的所有发电线圈中受磁力产生的磁力线变化。由此,只需作一次ANSYS静态数据计算,即可估算出直线发电机电动势,数据验证说明了结论的可行性。

The article introduces simple method of estimation on induction electromotive force in linear generators is introduced. First, a two - dimension model is set up in ANSYS. After analyzing, the real flux changing which produces the induction electromotive force is similar to the situation that causes in all the windings at a particular moment. Therefore, after one calculation with ANSYS software, the induction electromotive force can be estimated. Compared with the results of the experiment, the conclusion is proved to be reasonable.
