| General | A motor drive analysis is performed by integrating with MATLAB/Simulink. Fig. 1 is a flow of integrated analysis. Femtet analyzes basic characteristics with various conditions, and exports the results as a MATLAB-formatted script file. Fig. 2 shows an output setting. MATLAB/Simulink imports the result file to a perform motor drive analysis taking motor control into account. Fig. 3 is an example of the data import. Unlike a simplified PMSM (permanent magnet synchronous motor) model, the motor characteristics file obtained by the FEM analysis allows you to perform a motor drive analysis with detailed motor characteristics taken into account. Fig. 4 shows analysis results. The profile of the nonlinear counter-electromotive force is shown, which cannot be analyzed with a simplified PMSM model having fixed counter-electromotive force. *For this analysis, the optional license Femtet Advanced Magnetic is required. |
