چکیده :

In this paper, a comprehensive process for the optimal design of an integrated motor-drive (IMD) system using coupled electromagnetic-thermal multiphysics simulation is presented. In the proposed method, the drive system is implemented in the MATLAB-PLECS environment, and the machine's two-dimensional (2D) magnetic and three-dimensional (3D) thermal simulations are performed in finite element (FE) software. The coupling between the different parts is established through an automated code in Python, such that after each simulation cycle, the temperatures obtained from the thermal analysis are used to update the temperature-dependent parameters of the motor and drive. This iterative process continues until temperature convergence is achieved. After model validation, sensitivity analysis is performed on a set of motor and drive parameters to determine their direct and mutual effects on motor and drive performance indicators. Then, nine key parameters are selected and multi-objective optimization is performed based on technical and economic criteria using different weighting factors. The results show that the optimal structure resulting from the proposed process provides significant improvements in efficiency, torque ripple, thermal stability, and cost of the system compared to the initial design.
