Abstract:
This Master thesis desires the design of methodology for calculating shaft deflection and critical speed of electric machines. There are two methods used. The first one is transfer matrix method, which is represented by a simple programme for shaft creation and calculating needed results built in the Matlab software. The second one is finite element method, which is presented in the Ansys Workbench software.

Abstract:
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.

Abstract:
This master’s thesis deals with a permanent magnet synchronous machine calculation. In the first part of the thesis, the synchronous machine in general is described. Knowledge of these machines is essential for the remaining parts of the thesis. In the next part, an analytical calculation process of a given permanent magnet synchronous machine is presented. The given machine had already been manufactured before the thesis assignment. The calculation is to be adapted to the given machine. This way the parameters of the calculated machine should match the reference machine. The accuracy of the calculation can then be evaluated. Furthermore, calculations of the machine using Ansys RMxprt and Ansys Maxwell 2D are presented. The calculations are then compared with data obtained by measurements performed on the given machine. In the last part of the thesis, a modification in the analytical calculation is made to reduce the inaccuracy of the calculation. The thesis is concluded by evaluating the results.

Abstract:
The Master's thesis deals with the mechanical design of electric machine rotor. Within the first two chapters of the practical part of the thesis two simplified computational models of the rotor (level 1 models) are compiled. Specifically, the model of flexible rotor mounted on rigid supports and model of rigid rotor mounted on flexible supports. The essence of these computational models lies in solvability using simple equations. Using these models can save time when constructing a pre-design of the rotor geometry. The following chapter is devoted to comparing different approaches to computational modeling of rotor using FEM. A predetermined preliminary design of a high-speed massive rotor is investigated. Computational models of different levels at stress-strain analysis and modal analysis are presented. It also includes a suggestion on how to proceed effectively in a given analysis.
