To the President of Maysan University, Adel Man’e Dakhil, who chairs the committee discussing the master’s thesis in electrical engineering at Maysan University by researcher Abdullah May Fazza, entitled:
(Mathematical Modeling of High-Speed Solid Rotor Induction Motor Based on 3D Electromagnetic Field Analysis).
The discussion was held on Wednesday, September 3, 2025, at the faculty of engineering, University of Maysan, and in the discussion hall in the Deanship of the faculty of engineering building.
The discussion committee consisted of:
– Adel Man’e Dakhil – President / (University of Maysan / faculty of engineering).
– Muhammad Khalaf Jumaa – Member / (University of Maysan / faculty of engineering).
– Osama Yassin Khudair – Member / (University of Basra / faculty of engineering).
– Ahmed Thamer Radhi – Member and Supervisor / (Southern Technical University / Technical Engineering College, Maysan).
This thesis presents a comprehensive study on the mathematical modeling of high-speed solid-rotor induction motors, applying approximately three-dimensional electromagnetic field analysis. High-speed induction motors are increasingly used in various industrial applications due to their high power density and efficiency. However, accurately predicting their performance under different operating conditions remains a major challenge due to the complex interactions between electromagnetic fields and rotor dynamics at high speeds.
The research begins with the development of a detailed mathematical model representing a simplified three-dimensional electromagnetic field inside the engine, and then the rotor impedance is extracted. The study then extends to the DQ model, where derived equations are used to simplify the dynamic behavior of the engine.
Furthermore, the thesis demonstrates the application of the advanced model in MATLAB software, enabling engine simulation and analysis under different operating conditions.
Finally, the modeling of the harmonic circuit in MATLAB is simulated using an inverter to generate a five-level AC waveform from a DC source, and its effect is demonstrated. The results provide valuable insights into improving the design of high induction motors.
