双定子感应电动机等效电路分析

NEW EQUIVALENT CIRCUITS OF 3 PHASE TWIN STATOR INDUCTION MOTORS

首先引入旋转等效的概念，将双定子感应电机两个定子之间的相对旋转，看成定子不动，而转子对应部分扭转了一个角度α，此基础上，又通过引入“相位折算”的概念，将两个定子之间旋转角α的变化，等效为转子相绕组有效匝数的变化，于是能够进行绕组折算，得到折算后的基本方程式，进而导出与常规感应电机相似的“Ｔ”形和“Γ”形等效电路。

This paper presents new equivalent circuits for twin stator induction motors. To get the new circuits relative rotating between two stators of the motor is replaced by equivalent turning round between two corresponding parts of the rotor. On the basis, the variations of rotating angle between the two stators are converted into the changes of effective turns of the rotor windings, thus supply voltages of two stators in the new circuits are in phase.
