摘要：

This paper presents an accurate method to extract parameters of induction motor (IM) from finite element field solutions. A 2-D non-linear time-harmonic application of IM is used in the simulation. And to separate the leakage reactances, the frozen permeability method is used in the static magnetic field simulation for the slot leakage flux calculation. Then, the slot leakage reactance and the harmonic reactance can be determined separately with the consideration of skin effect and the saturation. A defect of modeling the rotation of rotor in time-harmonic field is pointed out in this paper. Finally, the determination of reactances as a function of speed variation is concerned. An application example is provided to confirm the accuracy of the presented method.
