In this paper , firstly we analyse the distribution of the magnetic field in the permanent magnet canned motor pump which rate power is 15kw , and calculate the reactive electromotive force , armature reactance parameters of this motor pump with no loads and loads 本論文運(yùn)用有限元方法分析了一臺(tái)15kw稀土永磁同步屏蔽電泵內(nèi)部磁場的分布情況,得到了在空載、負(fù)載等不同情況下,電泵的氣隙磁密分布磁場,計(jì)算了反電動(dòng)勢和電樞反應(yīng)電抗等參數(shù)。
