Improved Parametric Representation of IM from FEM for More Accurate Torque Predictions: Simulations and Experimental Validations
Artikel i vetenskaplig tidskrift, 2024

In this work, an updated methodology to determine the parameters of three-phase induction machines (IMs) is developed and presented. The goal of this determination is to achieve a better model representation of induction machines for the usage of a circuit-based control system. First, the theory of the T-form model (TFM) and the inverse Γ-form model (IGFM) are reviewed. The former review becomes the foundation of the following interpretation of the developing methods for identifying the needed parameters. Next, a 2D electromagnetic finite element method (FEM) model of a 15kW IM is utilized to demonstrate the strength of the methodology on a real machine. Furthermore, a comparison of results using the conventional test and the newly proposed method is presented, demonstrating the strength of the proposed procedure with enhanced accuracy for the torque and slip prediction. Lastly, experimental results using a 15kW IM are utilized to demonstrate the usefulness of the proposed parameter determination procedure.
