Measurement and simulation of synchronous reluctance machines
Gábriš, Richard ; Bárta, Jan (referee) ; Vítek, Ondřej (advisor)
This semester thesis describes the principle of operation and a usage of synchronous reluctance motors. The core of the thesis is devided into two parts. The first one is a description of a measurement of motor samples and evaluation of the measurement. Subject matter of the second one is designing of motor models in application ANSYS Maxwell, analysis of the results and their comparison with the results obtained by the measurement.

Design of synchronous reluctance motor
Koshelev, Maxim ; Ondrůšek, Čestmír (referee) ; Vítek, Ondřej (advisor)
Master thesis deals with analysis of the definite synchronous reluctance motor with salient poles and design of synchronous reluctance motor with barriers for magnetic flux. The work is divided into five parts. In the first part there is a brief overview of realized synchronous reluctance motor designs and also operating principle of motor of this type is described. The next part contains the basic parameters of the synchronous reluctance motor with salient poles; the parameters were found with analytical calculation. The third part demonstrates verified by means of FEMM results of analytical calculations for linear and nonlinear states and with transient analysis of motor using Ansys Maxwell environment. In the following part results of testing of the synchronous reluctance motor with salient poles are presented as well as the comparation of these results with calculated values and the results of simulations. The closing part of the thesis shows the design of synchronous reluctance motor with barriers for magnetic flux. All obtained parameters were examined using FEMM and Ansys Maxwell. The final version of the proposed motor was analysed when supplied directly by mains and through the converter by Maxwell- Simplorer co-simulation.

Preference Based And Ideal Multi-Objective Optimization Applied On Hightorque Ferrite Assisted Synchronous Reluctance Machine
Knebl, Ladislav
This paper introduces comparison of optimization algorithms applied on high-torqueferrite-assisted synchronous reluctance machine. The comparison is focused not solely on two algorithmswithin the same multi-objective optimization approach - preference based or ideal, but also oncomparison of these two approaches. The genetic algorithm and self-organizing migrating algorithmin both approaches are used to find optimal solution. The optimization goal is an optimal parametercombination to achieve the highest torque and power factor, while developing the lowest torque ripple.The optimized design will be evaluated by the 2D finite element analysis in steady-state analysis.

Permanent Magnet Assisted Synchronous Reluctance Motor
Knebl, Ladislav
In these days, there is big emphasis put on electric motors efficiency, the best efficiency can be achieved with surface mounted permanent magnet (SMPM) motor. The SMPM motors efficiency may be even in cases of small machines, higher than 90%. Unfortunately this kind of motor is expensive, because neodymium magnets are used. The synchronous reluctance assisted motor (SRAM) topology is one of many possible machines that might in some cases replace the SMPM machines. Because cheap ferrite magnets are used and still similar characteristics can be achieved.
