Design of bench type drilling machine
Malásek, Petr ; Marek, Tomáš (referee) ; Blecha, Petr (advisor)
The subject of this thesis is description of bench drill, research about companies producing bench drills and analysis of their products. Based on research, parameters of drill are chosen, 3D model is designed and basic calculations are calculated. The output of this thesis is 3D model of bench drill and drawing of assembly.
Experiences in Matrix Converter Induction Motor Drive Implementation
Lettl, Jiří ; Bednář, M.
In this paper a special attention is paid to the indirect space vector modulation design based on the virtual DC-link concept. The entire converter is interpreted as a series connection of two matrix converters (rectifying virtual matrix converter and inverting virtual matrix converter). Thanks to this insight it is possible to compose the modulation strategy for the entire matrix converter from the rectifier and inverter part modulations.
Vliv nulové složky statorových proudů na magnetické pole a přídavné ztráty asynchronního motoru v nouzovém chodu
Schreier, Luděk ; Bendl, Jiří ; Chomát, Miroslav
Two-phase feeding of induction motors under emergency operation from a voltage-type converter controlled so that currents of connected stator phases can have the required amplitude and phase shift is analysed. Based on the analysis the amplitudes and the phase shift of the fundamental time harmonic of the converter output currents are determined so that at required torque the machine can operate with minimum stray losses.
