Noise suppression of six pole induction machine
Lexa, Jakub ; Janda, Marcel (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with noise of electromagnetic origin of six pole three-phases induction machine. Task thesis was rendering literature review. Analysis of the problem consists of various analytical calculations using Matlab and subsequent comparison of results with measured data on real induction machine. The last part of thesis is a summary of conditions for induction machine with low noise.

Analysis of 1,1 MW permanent magnet synchronous motor
Homolová, Romana ; Cipín, Radoslav (referee) ; Vítek, Ondřej (advisor)
This thesis deals with the elaboration of The Permanent Magnet Synchronous Motor and the calculation of its parameters. In the first part, the construction and used permanent magnets of this motor are listed here. The next part of the thesis contains a short overview of the stator windings, the calculation of the winding factors and calculation of the basic parameters of the stator winding. The calculation of the magnetic induction in the air gap is also illustrated here. The result is recalculated by using the Carter factor and then the value of the first harmonics of air-gap flux density is determined. The result is compared with the analysis in the program FEMM. The next part of the thesis is creating a comprehensive overview of the machine using a replacement circuit diagram and phasor diagrams. Finally, the thesis contains model created in RMxprt and ANSYS Maxwell. The results of the model analysis are compared with the analytical calculation
