Calculating the temperature field distribution in an electrical machine

This diploma thesis deals with methods used to determine the temperature field distribution within an electric machine. The first part is focused on methods of temperature measurement, generation and transfer of the thermal energy within the electric machine, asynchronous motor in particular. The thesis describes classical methods of temperature measurement and it also deals with ANSYS Workbench finite element method for thermal analysis of the motor. The final part of the thesis is focused on a comparation of all discussed methods with respect to results of thermal test for real asynchronous motor and concludes the most proper method
