Thermal model of high-speed induction motor
Světlík, Martin ; Mach, Martin (referee) ; Toman, Marek (advisor)
This thesis deals with thermal calculation of high-speed machines. Distribution of electrical rotating machine losses and calculation of mechanical losses in the air gap and on the ends of rotor is described in first part. Based on relationships taking into account rotor friction of the against the surroinding fluid are these calculations make. Literary search on theme of thermal calculation and principle of calculation thermal network method is descript here in the next part. Thermal network designed for specific machine and tabular of resulting temperatures are located in the last part.

Measurement and analysis of high speed squirrel cage induction motor
Kaczmarczyk, Ruben ; Mach, Martin (referee) ; Klíma, Jiří (advisor)
The thesis is focused on familiarization with classical asynchronous and high-speed motors, their construction and principle. There are also described constructional peculiarities of the high-speed motor and comparison of losses between both motors. Then, on the basis of production documantation a simplified calculation of the particular asynchronous motor is made. Analytical calculation is also made in RMxprt program after setting of all given parameters of the motor. Experimental measurment upon the laboratory sample for the verification of given qualities is also embodied in the bachelor thesis.
