摘　　要：同性极感应子电机是一种特殊的凸极同步电机,双反应理论是否可以适用于该电机的瞬态分析还存在争议。同性极感应子电机没有通常实际物理空间意义的d、q轴,在一般凸极同步电机瞬态分析中适用的d、q变换和叠加原理,在同性极感应子电机中必须使用更加复杂的程序来实现,直接使用a、b、c空间坐标系矢量变换分析同性极感应子电机的瞬态特性更为方便。该文采用三相电机a、b、c绕组变量的空间矢量法来计算同性极感应电机在考虑各绕组电阻情况下的三相短路电流。Homopolar inductor alternator （HIA） is a special type of salient pole synchronous motor, and there is muchdiscussion that whether two-reaction theory can be applied in the analysis of this alternator or not. But there are not usualpractical physical space d-axis and q-axis in HIA, d、q transform and superposition principles which are applied in HIAshould be more complex than that in transient analysis of the general salient pole synchronous motor. Therefore, it is moreconvenient that the a、b、c vector transformation of the space coordinates is applied to analysis the transient characteristics ofHIA directly. In this paper, three-phase short circuit current of HIA considering winding resistances was calculatedthrough the a、b、c vector transformation method of the space coordinates.
