基于气隙基波磁场交流电机电感参数的统一计算公式

Unified Expression for Calculating Inductances of AC Machines

在考虑气隙基波磁动势产生基波磁通密度的情况下,推导了计算交流电机电感参数的统一公式。根据等效整距集中绕组与实际绕组产生相等基波磁动势的原则,给出了实际定子绕组与转子绕组的总有效匝数表达式。分别以三相同步电机与十二相同步电机为例,说明了统一计算公式的具体应用过程,并证明了公式的准确性和有效性。

The unified expression for calculating inductances of AC machines is derived by only considering fundamental component of flux density due to fundamental air-gap MMF. Based on the principle that an equivalent full-pitch, concentrated winding gives the same fundamental MMF as the actual one, the effective number of turns of the equivalent winding is obtained. A three phase synchronous machine and a twelve-phase synchronous machine are selected as examples to show the correctness and effectiveness of the formulas.
