1·The accuracy of equivalent circuit method can be effectively improved if the calculation of PM leakage permeance is accurate.
准确计算永磁漏磁导可以有效提高等效磁路法计算精度。
2·The stator cogging effect is usually ignored when we calculate generator magnetic field by air gap permeance method, which lead to the generator fault information missing.
采用气隙磁导法计算发电机磁场时通常忽略定子齿槽效应，漏掉了发电机的故障信息。
