Electromagnetic finite element modelling of electrical machines using open-source tools
Žíla, Jakub ; Klíma, Jiří (referee) ; Bárta, Jan (advisor)
This bachelor thesis deals with electromagnetic computation by opensource softwares. The simulation of three-phase permanent magnet synchronous motor is made using opensource programs. Results of simulations are compared with professional software ANSYS Maxwell and with measurements on the machine. All softwares in this thesis use the finest element method for a computation.
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.
