FEA-Assisted Experimental Parameter Identification of Induction Motor

Abstract

This paper proposes an experimental parameter identification method for induction motor drives. To find the motor parameters at each operating point, the rank-deficiency problem is circumvented by the finite element analysis (FEA). The stator inductance look-up-table (LUT) is constructed assisted by FEA, and the leakage inductance and the rotor resistance are calculated based on the experimental tests. The proposed parameter identification can be used for a wide range field-oriented control in the traction motor. The proposed parameter identification is verified with the experimental tests.
