摘要
本文根据直流电机换向理论 ,给出了一种分析直流电机换向火花的方法。这种方法的基础是电机换向过程暂态电磁场的时步有限元法计算 ,其重点是采用磁场迭代法计算出实际的附加换向电流。通过直流电机火花因数的计算 。
Based on the theory of commutation in DC machines, this paper describes a numerical analysis method for analysis of the commutation spark. In this method time stepping FEM is effective, and the additional commutation current is obtained with the iterative calculation of the commutation magnetic field. It shows the additional commutation current can be related directly to the commutation analysis.
