考虑差分电感效应的单相励磁模式下感应电机磁化曲线估计

To obtain an accurate magnetizing curve of induction motors at standstill, including both field-weakening region and saturated region, a novel method for estimation of mutual inductance Lm is proposed. At first, the reasons causing error of Lm identified by conventional ac-current-injection-based method, i.e., fluctuation of static Lm and differential inductance effect, are clarified in a theoreti...
