Machine learning as a design aid for electrical machines

Adding machine‑learning (ML) tools to the electrical‑machine design process can replace many costly finite‑element analyses (FEA). This project looks at using surrogate models, neural networks, and regression‑type ML algorithms to estimate important electromagnetic results such as torque ripple, core losses, and efficiency maps. We start with existing FEA results or with new parametric simulations, then train several ML architectures on that data. The goal is to see how accurately each model predicts the metrics and how much faster it runs compared to a full FEA. The workflow focuses on three main steps. First, we clean and prepare the data. Next, we pick features that describe the machine’s geometry and materials.

Finally, we tune each model’s hyperparameters to get the best performance. To turn the trained models into design tools, we combine them with optimization methods like genetic algorithms or particle‑swarm optimization. This lets us run rapid multi‑objective optimizations without running a new FEA for every design change. The result is a set of fast, high‑fidelity design aids that can cut the number of design iterations needed for permanent‑magnet synchronous machines or induction motors. By using these data‑driven models, engineers can keep the accuracy of electromagnetic simulations while getting near‑real‑time feedback during the design process.
