Calculation of induction machine stray looses
Jirásek, Tomáš ; Kurfűrst, Jiří (referee) ; Ondrůšek, Čestmír (advisor)
The main goal of this thesis is a determination of an idle additional losses in an electric rotary machines and a calculation of these losses for induction machine. The additional losses are caused especially by the eddy currents on the surface of stator and rotor, further by a pulsation of these currents owing to the periodical change of air-gap permeance, magnetic induction in stator and rotor teeth and a differential leakage.

Stray losses calculation of induction machine
Jirásek, Tomáš ; Hájek, Vítězslav (referee) ; Ondrůšek, Čestmír (advisor)
The main goal of this thesis is a determination of an idle stray losses in induction machine and creation calculation program in MATLAB. The stray losses are caused especially by the eddy currents on the surface of stator and rotor, further by a pulsation of these currents owing to the periodical change of air-gap permeance, magnetic induction in stator and rotor teeth and a differential leakage. Value of stray losses are different of engine construction especially by it are scoring insulated, uninsulated, straight or slant.

Induction motor powered from inverter
Fiala, Petr ; Huzlík, Rostislav (referee) ; Ondrůšek, Čestmír (advisor)
This master’s thesis studies additional losses generated in the induction motor powered from inverter. The first chapter was used for literature search and it mentions valuable publications. The second chapter discusses the different types of losses in the induction motor. The third chapter describes other negative effects on motor caused by inverter, the fourth one defines possible measuring methods, which would lead to the quantification of additional losses. The fifth chapter introduces the electromotor tested as well as the measuring instruments used. The last chapter presents pivotal results of the measurement in the testing room.
