The fault diagnosis of electrical machines during startup transients has received increasing attention regarding the possibility detecting faults early. Induction motors are no exception, and motor current signature analysis become one most popular techniques for determining condition various components. However, in case inverter powered systems, a is difficult to determine from stator because ...

An accurate method of estimating the efficiency of in-service motors is needed in order to determine the performance of installed motors without disrupting the motor driven process.. In this paper, the motor efficiency is estimated using a non-intrusive implementation of the compensated slip method. The motor speed is accurately estimated using motor vibration signature analysis. A few other ef...

Human subjects can quickly adapt and maintain performance of arm reaching when experiencing novel physical environments such as robot-induced velocity-dependent force fields. Using anodal transcranial direct current stimulation (tDCS) this study showed that the primary motor cortex may play a role in motor adaptation of this sort. Subjects performed arm reaching movement trials in three phases:...

This paper introduces a fault diagnosis method for mine scraper conveyor gearbox gears using motor current signature analysis (MCSA). approach solves problems related to gear characteristics that are affected by coal flow load and power frequency, which difficult extract efficiently. A is proposed based on variational mode decomposition (VMD)–Hilbert spectrum ShuffleNet-V2. Firstly, the signal ...

Several researches claim that the vibration technique, widely used in industry, is more efficient compared to stator current analysis diagnosis of mechanical faults. On other hand, show technique advantageous especially electrical faults, addition simplicity sensor positioning. The aim this paper both techniques can be complementary. For this, a comparative performances achieved. To end, fault ...

recently, researches on motor learning have illustrated that learning with effortless process supports learning under psychological stress. also, contextual interference and practice specificity theories are among those theories which investigate desired practice conditions. the current study aimed at identifying cognitive effort and effortless process based on contextual interference and pract...
