Abstract: The temperature field of automobile alternators was simulated and analyzed. According to its structure symmetry, the calculation domain was simplified. Based on the theoretical analysis of heat transfer, the heat thermal conductivity of the components was analyzed. Adding the heat boundary conditions, and analyzing the alternators loss, the temperature field of automobile alternators was simulated. The temperature distribution and heat flux vector diagram of alternator core, winding and squirrel guide bar at a stable operation was got, and the largest heat and heat conduction direction of the alternators was analyzed, which laying the foundation for optimizing automotive alternator.
Key words: automotive alternators; finite element analysis; 3D temperature field |
