急求 150MW 2极汽轮发电机电磁计算公式手算的
150MW 2极汽轮发电机电磁计算公式手算的 这个一般不会有人给吧，你只有去找公式《DZ 28-63汽轮发电机电磁计算公式》，然后自己算就是啦 恩 关键是没数据。想求一个算例 请问你有没有算例呀，小弟感激不尽！ 看来楼主这个人，什么事你都好奇，好奇心太重，算这个没有什么意义。 有没有搞错，150MW的还是2极的？这么快的转速，这么大的发电机，有吗？ 150MW 2极汽轮发电机电磁计算公式手算的？中国人现在还没有 {:1_432:}{:1_432:}{:1_432:}{:1_432:}{:1_432:}{:1_432:}{:1_432:}{:1_432:}{:1_432:}{:1_432:} 回复 7# 阿牛2005不能吧 150MW发电机 不算大啊 以前还能算中型的 现在早就算是小型的了 NON-SALIENT THREE-PHASE SYNCHRONOUS GENERATOR DESIGN
