Temperature determines the energy release rate of secondary high explosives. Thus, it is critical to know temperature applied an explosive predict its response impulse. However, measuring internal a heterogenous solid undergoing in detonation has many technical challenges. We will discuss several measurement techniques, their strengths, and limitations, propose alternative route assessing effec...

An important factor in industrial progress during the past five decades has been the increasing sophistication of factory automation which has improved productivity manyfold. Manufacturing lines typically involve a variety of variable speed motor drives which serve to power conveyor belts, robot arms, overhead cranes, steel process lines, paper mills, and plastic and fiber processing lines to n...

 Traditional high-frequency pulse width modulation (PWM) inverters for motor drives have several problems associated with their high frequency switching which produces high voltage change (dV/dt) rates. Multilevel inverters solve these problems because their devices switch at the fundamental frequency. Two different multilevel topologies are identified for use as a converter for electric drive...

Three-phase induction motors have been used in a wide range of industry applications. Using modern technology, the speed of induction motor can be easily controlled by variable frequency drives (VFDs). These drives use high speed power transistors with various switching techniques, mainly PWM schemes. For several decades, conventional control systems were applied to electric drives to control t...

In this paper controlled electrical drives for Rail Mounted Wide Span Gantry Cranes are analyzed. The modern solution considers the application of frequency converters for all drives. Special attention is payed to multi-motor drives of horizontal movement in the sense of load distribution. Although it can be considered that motors are rigid coupled by mechanical construction, they do not need a...
