In present scenario permanent magnet (PM) machines are widely used due to its higher power density, better speed versus torque characteristics, high dynamic response and high efficiency. Thermal model is generally used for the design improvement of a machine and to assess the loading capability under different working conditions. This paper presents the thermal modelling, based on lumped parameters, for a natural-cooled dual stator five phase permanent magnet synchronous generator (PMSG). The model proposed in this paper has twelve nodes to find temperature in different parts of the machine. Model is developed in MATLAB environment and the results are validated using Finite element method(FEM) results. Though Finite element thermal model is considered to be more accurate than lumped parameter thermal model, it takes significant time for simulation and design improvement.
