The article is devoted to the use of Park’s vector method for operational control rotor condition induction motors traction and auxiliary drives railway rolling stock. In course analysis, it was established that in order increase reliability efficiency operation vehicles, necessary improve implement diagnostic systems monitoring current state most damaged elements electric built into drive. Thi...

The paper investigates the relative influence of centroid three-phase squirrel cage induction motor rotor bar cross section, on breakdown (maximum) torque machine. angle taper, top width and radial depth as established design variables, were also investigated so to properly situate degree centroid, in comparison; far maximum is concerned. machines their steady state operating mode using equival...

Squirrel-cage fans are widely applied in air conditioning systems, and their aerodynamic noise mainly related to blade length. The performance spectrum of squirrel-cage synchronously measured an anechoic wind tunnel. effect lengths different geometric configurations on the a fan is experimentally investigated. This paper focuses total sound pressure level characteristics at measurement points. ...

The increasing of world population, forced human beings to produce clean energy, more creative solutions have been developed use the energy with most efficient way. Researches on this topic still working today. Nowadays, new electrical machines are invented and currently used ones being continue be improved. In industry, if a survey is made according electric motors, it will seen that, inductio...
