Analysis of electromechanical parameters of a historical induction machine and their comparison to a modern machine
 Muczka, Vojtěch ; Patočka, Miroslav (referee) ; Vorel, Pavel (advisor)
This thesis is related to a renovation of a historical induction motor and parameter comparison with modern equivalent. The first part describes the working principal of an induction motor. The next part is dedicated to the process of renovation of this motor, measurements and calculations of its parameters, followed by evaluation of parameter differences between historical and modern motor.

Increase of efficiency of a single phase induction machine
 Muczka, Vojtěch ; Klíma, Jiří (referee) ; Mach, Martin (advisor)
This thesis is dedicated to efficiency increase of one phase induction machine through material change of induction cage and rotor slot shape optimization under the condition of maintaining the same locked-rotor torque. In the first part of this thesis is the explanation of induction machine principles. Next is the comparison of measured and simulated parameters of small one phase machine from ATAS company. The following part is dedicated to the analysis of rotor slot shape and ring size influence on machine parameters when using pure aluminum instead of resistive alloy. The next chapter deals with slot shape optimization in the program RMxprt, controlled by genetic algorithm written in MATLAB interface. In the final part are the resultant slot shapes simulated in Ansys Maxwell using finite element method and then the measured, simulated and expected parameters are compared.
