摘要

Induction machines (IMs) are widely used due to their robustness, low cost, and reliable performance. However, challenges such as magnetic saturation, manufacturing constraints, and accurate loss estimation remain critical in IM design. Many existing design approaches—such as subdomain models, magnetic equivalent circuits, and optimization algorithms—often involve high computational cost, limited accuracy, or neglect practical constraints. This paper presents a comprehensive analytical design methodology for induction machines supported by a custom VB.NET–based software tool. The tool provides analytical estimation of machine dimensions, slot geometry, flux density, magnetizing current, and equivalent circuit parameters, while enabling designers to select optimal configurations based on cost, efficiency, or balanced performance criteria. Finite Element Method (FEM) analysis is employed to validate the analytical results, evaluate magnetic flux distribution, saturation behavior, geometric effects, and losses using material-specific B–H curves. A prototype IM is manufactured and experimentally tested under no-load and short-circuit conditions. The results show strong agreement between analytical calculations, FEM simulations, and experimental measurements, with errors ranging from 0.18% to 5.3%. These results confirm the accuracy and effectiveness of the proposed software as a fast, flexible, and reliable platform for induction machine design.
