Derivation process of relationship between magnetic motive force space vector and current space vector in induction motors

利用电机统一理论及功率不变正交变换推导了感应电机中定子磁动势与定子电流空间矢量以及转子磁动势与转子电流空间矢量的关系表达式,给出了它们在电机空间复平面中的复数表达式,阐述了其物理意义,最后以一个实际的绕线式转子异步电机为例,通过在m atlab仿真平台中编程,得出了仿真曲线,仿真结果表明所推导的表达式是正确的。

According to the general electric machine theory and orthogonal transformation with constant power, the relationship expressions of the stator magnetic motive force （MMF） space vectorfz and the stator current space vector i, as well as the rotor MMF space vectorfr and the rotor current space vector ir were deduced. Further more, the complex number expressions of their relationship in the motor space complex plane were given, and the physical significance was illustrated. Finally, parameters of a practical wound lotor induction motor were used to test the expressions through programming in the Matlab platform. The simulation curves were presented, and the simulation results proved the expressions correct.
