Analysis of the stator and rotor pack termination effect on the synchronous machine by FEM
Michailidis, Petr ; Valenta, Jiří (referee) ; Skalka, Miroslav (advisor)
This thesis deals with simulation’s possibilities of the electromagnetic fields in electrical machines. A finite element method is the final element technique. The content of this thesis is a model and mesh creation and electromagnetic simulation of synchronous machine. The stator and rotor pack termination effect on the synchronous machine.is analyzed by finite element method in ANSYS program. The type of the stator termination pack is described by four segments. The magnetic field distribution is deformed due to the material properties of used segments. In the next part a methodics of mesh creation is shown. The mesh quality (in term of elements number and elements shape) is important due to the solution accuracy and speed.

Analysis of damage to the rotor bars of induction machines
Henzel, Roman ; Michailidis, Petr (referee) ; Skalka, Miroslav (advisor)
This bachelor thesis deals with disorders of induction machines with focus on the failure or damage to the rotor bars or end rings. The work includes a literature research of the low resistance measurement, which can be used to determine the rotor bar resistance of the squirrel cage induction machine. The experimental measurement of the analyzed motor with the following conditions (short-circuit, no-load and load) is also includes. The magnetic model of the machine was described and created in MAXWELL and results were compared with the LabVIEW software (in order to verify the accuracy of the particular simulation). Analysis results evaluation of three phase squirrel cage induction machine with broken rotor bars was done.
