The analysis of dependence of the magnetic losses in hauling electric motors on the frequency of armature remagnetization is presented. A universal characteristics of the magnetic losses reduced to the frequency of remagnetization of 50 Hertz is offered.

The value of saturation factor for traction D.C. motors, which allow promoting the  accuracy of calculations based on application of universal magnetic characteristic, is offered. 

The idea of increase the calculations exactness based on application of universal magnetic characteristic due to value variation of satiation factor is considered.

-

A number of functions for approximating the universal magnetic curve and its derivatives, their accuracy and conformity to the requirements put forward by the authors have been studied.

This study investigates the effect of attracting and repels magnetic fields with the materials of vegetable oil in the form of a mixture of coconut oil and jatropha (B50) against the behavior of stability and characteristics of flame in the process of pre... see more

To investigate the variation in the characteristics of rock microstructure after cyclic dynamic disturbances, a split Hopkinson pressure bar (SHPB) was used to carry out cyclic dynamic impact tests on granite, and the P-wave velocity was used as the chara... see more

The study objective is to investigate the combustion characteristics of Callophyllum inophyllum fuel in presence of a magnetic fields. To conduct the experiment, a bunsen burner was utilized, with fuel and air being dispensed via a syringe pump and compre... see more
