Electrical machine thermal protection
Němec, Martin ; Huzlík, Rostislav (referee) ; Mikulčík, Aleš (advisor)
This bachelor´s thesis deals with proposal for thermal protection of single-phase motor. The single part of thesis is devoted to collocation of motor temperature. Knowing this issue is important for thermistor right location. The parameters measuring and the model of simulated scheme are described in following parts. The simulated scheme is created in the Matlab programme, in a programme´s superstructure Simulink. At the close of this thesis, there are values measured and simulated compared.

Thermal characteristics of power conductors
Měrka, Ivan ; Novotný, Jan (referee) ; Orságová, Jaroslava (advisor)
This bachelor’s thesis aims to theoreticaly analyze thermal phenomena in power conductors and construct a simulation of thermal characteristics of conductor under load. First, power conductors and their classification is discussed. Following are elementary information in thermomechanics and ways of heat transfer. Next chapter talks about different ways of cable laying with respect to their steady temperatures and the design of conductor’s cross section. Further chapter focus on unsteady state of the heating conductor, analysis of Van Wormer’s method for acquisition of thermal characteristics and in this method the model for parameterized conductors is based. In conclusion the simulated results are verified and compared to the results of practical laboratory measurement.
