1.设计的永磁同步电机,在进行静态分析的时候,加的励磁 是指满载的情况吗?下面这段话 ,翻译我懂,但怎么去理解The coils are partially represented in the model. We need to enter the current that flows in and out inside each coil. The excitation is realized through a balanced three phase system. For instance, in our example, we apply:
1500 A to PhaseA
-750 A to PhaseB
-750 A to PhaseC.
In the Magnetosaticsolver, the sources are given in terms of currents. We do not need to model each turn at this stage; therefore we only enter the total current in each phase. The number of turns and the electrical topology are only taken into account for the inductances calculation.
Current terminals need to be created to apply the loads. The terminals consist in 3D sheets that are normal to current directions. The 2D sheets are defined thanks to plane sections. 我不知道这个电流的值是相电流?线电流?还是 相当于加了负载之后的电流?
2.如果 我把设计好的电机去8分之一的模型 进行仿真 ,得出来的 转矩等参数 具有整体性吗?能表示这个电机的转矩等参数吗?还是 计算的结果 得乘以 8?
3.永磁同步电机的 转矩 有公式吗, 因为 我参考的仿真例子里面 只提供了 最后加的电流 ,得出的转矩如何进行与计算值的校对呢?
有图为以上三个问题,希望各位大神 给予小弟帮助!!!多谢了!!!{:soso_e183:} |
