Zachycení sil působící na statorová vinutí extrémně namáhaných točivých strojů

Text is focused on questions concerning with forces reduction interacting at stator windings. On an example of special machine (short-circuit generator) there are shown basic methods how to solve stator windings with respect to forces reduction. This is solving of dynamic problem (shape...

Sledovanie štruktúr spojov na báze zliatiny SAC

Intermetallic compounds (IMCs) are essential part of lead-free solders microstructure. Presence of the IMCs results from solidification process of molten solder. In 96.5Sn3Ag0.5Cu (SAC305) solder is dominant element tin (Sn). But despite this Sn dominancy only 3% weight contain of silver (Ag...

Rozdělení budícího proudu turbogenerátorů velkých výkonů na jednotlivé kartáče sběrného ústrojí

Unequal distribution of excitation current between particular parallel brushes is generally known as well as a sequence of influences which these phenomena implicate. Measurements performed in former times by classical ampere-meters didn’t guarantee instantaneous information about all currents in fixe...

Vliv tvaru napěťových impulzů na rychlost stárnutí elektrické izolace

The impact of the fast voltage impulses on the reliability of insulation systems has been in the centre of interest for years. Till now, a negative impact of the fast voltage impulses have been documented and quantified. The reliability of the insulation is usually compared&#x...

Meranie teplotného profilu v prostredí nasýtených pár

The process of soldering has to guarantee suitable temperature conditions for formation of metallurgical joint between leads of components and conductive pads on printed circuit board. The formation of reliable and quality joint depends on temperature profile, which guarantees transformation of&#...

Zajištení bezpečného chodu strojů a zařízení

There always exists certain risk in operation of any equipment that will not work reliable or with failures presence. For overall risk minimization of an item we have to use protective devices with safety function performed. Diagnostic coverage is a measure of diagnostics efficienc...

Modifikovaná elektricky vodivá lepidla

Electrically conductive adhesives are nature friendly joining materials with continuously growing importance in the area of electrical engineering. They are used for electronics assembly of temperature sensitive components, which could be damaged by the temperature used for soldering, for montage ...

Analýza I(t) závislosti počas štrukturalizácie magnetických nanočastíc v magnetickej kvapaline

The previous experiments were devoted to observation of structuralization processes in magnetic fluids in dependence on time at constant value of homogenous magnetic fields. The average value of clusters of magnetite particles reached stabilized length that depended on volume concentration of...
