The master’s thesis deals with analysis of warming and cooling of synchronous machine. The warming is caused by the machine’s losses resulting from the conversion of electrical energy into mechanical energy. There then can be achieved high values of temperature on the machine, which can lead to destruction of the machine. The transient thermal analysis, working on the finite element program Ansys Workbench, is used for thermal analysis. As an appropriate instrument, which serves for flow calculation, a module CFX in the program Ansys Workbench may be used. In the practical part the model for unhampered alternator with current in the field winding only was measured and after that, the measured values were compared with the results of transient thermal analysis. Speed and progress of air flow through machine were analyzed with CFX module.
