The calculation of temperature field on a permanent magnet wind generator

The temperature field of a wind generator is analyzed by finite element method. The steady-state heat transfer mathematic model is set up, and hypothetical conditions are presented, together with boundary conditions and loads are calculated according to the heat transfer theory in air-cooling condition. Dealing with the calculation results of the temperature field of the wind generator, the temperature distributed diagram and several temperature curves of main parts of the wind generator are obtained. The analysis of FEM is verified by the test results.
