摘　　要：传统电机学文献大都认为,从空载到负载时,变压器和异步机的激磁磁势保持基本不变。从反正两个方面论证了这一观点是错误的。详细提要请见本文的结语。In the traditional electrical machines references,it is mostly thought that the exciting MMFs of transformers and asynchronous motors are basically unchanged from noload to loading.This paper demonstrates that this viewpoint is wrong from both negative and positive aspects.The detail abstracts can be seen in the conclusions of this paper.

关 键 词：变压器 异步机 激磁磁势 磁势方程 磁势平衡 T形等值电路
