摘要
本文利用把转子端环电阻和端环漏抗计入转子导条电阻和槽漏抗的办法,对文献[1,2]的有限元计算方法进行了改进,弥补了二维计算的不足.本文计算的起动电流和起动转矩与实验值的对比表明,此文献[1,2]的计算值及采用路的方法的计算值更接近实验值.
In this paper, FEM method in references[1,2] is improved by considering the resistance and leakage reactance of end rings into that of bars of cage rotor, thus the deficiency of two dimensions calculation is remedied. The constrast of calculated and tested value of starting current and starting torque shows that the proposed method is more accurate than that of references[1,2] or the method of circuits.
