The paper describes the implementation and developing of the multi-level models for the electrical machine under study. The targeted approach was to create simulation programs with 3 different complexity levels. The first one was designed to use constant parameters of the machine, the second one engaged look-up table based DQ inductance variations vs. currents while the most complex one, was based on 3D matrixes for the DQ flux variations vs the currents. All these studies were engaged on a known permanent magnet synchronous machine for which the complete identification and design data is available. A finite element analysis (FEA) of the machine is performed in order to evaluate its electromagnetic behavior and perform the parameter computation. All the models are built in MATLAB/Simulink using Energetic Macroscopic Representation (EMR), an efficient tool for the control design and model organization.
