Calculations of temperature fields on the model of induction motor
Koníček, Pavel ; Makki, Zbyněk (referee) ; Janda, Marcel (advisor)
The aim of this work is to get acquainted with the construction of induction motor, the calculation of temperature fields in the motor model in ANSYS Workbench and subsequent evaluation of the results for different operating conditions. There is provided a general description of the function and design of induction motor, a summary of sources of heat inside the engine design, heat transfer theory, the basic description of the finite element method and ANSYS Workbench description. Furthermore, comparison of temperatures measured on a real engine with the values obtained from the calculation program.
Diagnosis of electromagnetic origin vibrations in asynchronous motor
Koníček, Pavel ; Dostál, Lukáš (referee) ; Janda, Marcel (advisor)
The aim of this master´s thesis is to introduce methods of diagnostics of vibrations in electrical machines. Describe the various vibration sources located inside and outside of the electric machine. Description of the sources of vibration is then preferably dedicated to vibration of electromagnetic origin. There is a description of the construction of an asynchronous motor and the magnetic circuit, the theory of vibrations and their origin. Described are also vibration sensor enables measurement and mathematical tools for their evaluation. In this work also practical vibration measurements on an asynchronous motor, data processing, their subsequent analysis and computer simulation of electromagnetic vibration origin. The conclusion of this work is devoted to the evaluation of the data obtained.
