旋转磁动势
rotating magnetomotive force
xuQnZhuon cldongshl旋转磁动势(rotating magnetomotive foree) 在空间绕着某一轴线旋转的磁动势。产生旋转磁动势的方法可以是机械的或是电磁的。进平发电机转子旋转时,转子励磁电流产生接近正弦分布的磁动势随之而转,形成旋转磁动势;而定子三相电枢绕组中有对称的正弦交变电流通过时,各相绕组产生的磁动势轮流地达到最大值,三相合成磁动势也是一个旋转磁动势,其幅值为;_生兰I只丝,A 兀P式中w为每相绕组的申联匝数;k为绕组系数;p为绕组的极对数;I为每相电流的有效值,A。 当同步发电机正常对称运行时,电枢绕组产生的旋转磁动势和转子磁极旋转磁动势以同一转速同向旋转,两者相对静止,形成平稳的电磁转矩,转矩的大小和定、转子旋转磁动势的大小及两者的相对位置有关。不对称运行时,发电机电枢电流三相不对称,除有与对称运行时相序为A~B~C相同的正序分量外,还有相序为A~C~B的负序分量存在,该负序分量电流会产生一个和转子转向相反的旋转磁动势,它和转子励磁磁场作用,将产生一个以两倍工频正负交变的转矩分量,总的电磁转矩将发生脉动而不平稳。此外,负序磁场还会在励磁绕组及转子铁芯等部件中产生感应电流、造成附加的损耗和发热。
