FEM Thermal Modeling of an Induction Motor
The circuit approach is still prevailing in thermal calculations of electrical machines. However, the finite element method (FEM) is gaining ground due to its advantages. The modeling by FEM is fast and flexible, the parameters once obtained are generally valid, the results cover the entire problem area and they can be clearly presented. The majority of commercial CAD-FEM programs includes thermal solvers which makes possible coupled electromagnetic-thermal analysis on the same model.
