Abstract :
A new model based on the MT synchronous rotating frame, including main path saturation, is developed to analysis the steady and dynamic performance of induction motors with vector control systems. The parameters calculated by finite element analysis (FEA) guarantee the exactness of the model. The simulation results, compared with those of experiments, validate the model in dynamic analysis. The experimental results also show that the proper selection of rotor flux level reduces the start-up time with higher instantaneous torque
