Research ArticleOpen accessIn the keywordsOn the Influence of Stator Slot shape on the Energy Conservation Associated with the Submersible Induction MotorsM. Sundaram, P. NavaneethanProblem statement: A good design of Submersible Induction Motor is required to maintain maximum efficiency level. This can be achieved in one way by optimum design of magnetic circuit. The magnetic circuit of an Induction Motor is formed by the combination of Stator core, Rotor core and air gap. In applications like Submersible Motor Pumps, the air gap cannot be … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,710 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRepower and Evaluation of New Power of Synchronous GeneratorsS.P.Y. Santos, E. Delbone, E.F. Carvalho, L.N. MartinsProblem Statement: Useful life of winding isolation is about 30 years. It can be reduced when it is submitted to overloads or when it is worked in aggressive environments. Approach: When retrofit is done, an increasing to superior isolation class is recommendable. So, generator capacity can be increased and pay back could be excellent justifying the investment. Result: Several Brazilian’s … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,800 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Antenna and Circuit Model for Charging an Electronic Device from the Ambient Electromagnetic WavesPankaj Chandra Kar, Md. Ariful Islam, Amit Paul et al.Electronic device use is on the rise as more and more tasks in everyday life are conducted online. As a consequence, charging is a unique aspect of any electronic device. However, the capacity of any electronic device's battery is fixed. On the other hand, charging the unit at any time and in any place is incredibly difficult. As a result, … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 1 · 18 Jan 2022 · 7,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransient Response of a Novel Displacement Transducer for Magnetic Levitation SystemMrunal Deshpande, Badrilal MathurProblem statement: In magnetic levitation system, position sensors are used to obtain a voltage proportional to the position of the suspended object. This is an essential feedback signal for stabilizing the system. These sensors make the system clumsy and prone to failures. To eliminate any physical attachment on the levitated object for the purpose of measuring its displacement, a novel … …American Journal of Applied Sciences, Vol. 8, Issue 11 · 5 Oct 2011 · 7,235 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Repetitive Transcranial Magnetic Stimulation on Dystonia: An OverviewSergio Machado, Oscar Arias-Carrion, Flávia Paes et al.Problem statement: Repetitive Transcranial Magnetic Stimulation (rTMS) is a noninvasive procedure whereby a pulsed magnetic field stimulates electrical activity in the brain. Dystonia is characterized by several disabling symptoms for which effective, mechanism-based treatments remain elusive. Approach: Consequently, more advanced non-invasive therapeutic methods were required. A possible method to modulate brain activity and potentially viable for use in clinical practice … …Neuroscience International, Vol. 2, Issue 1 · 29 Jul 2011 · 10,029 accessesView PDFCite

Research ArticleOpen accessIn the abstractEstimation of Vibrations in Switched Reluctance Motor DrivesS. Balamurugan, R. ArumugamThis study discusses a simple algorithm for estimation and reduction of Vibrations in a Switched Reluctance Motor (SRM) using magnetic circuit simulation in MATLAB/SIMULINK Environment. A Non-linear model is developed using magnetic circuit equations, wherein non-linearity is added using a inductance profile with back EMF. Dynamic characteristic of the SRM is simulated and the same is being verified experimentally. In … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 6,826 accessesView PDFCite
Review ArticleOpen accessIn the abstractNikola TESLARelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella et al.Nicolae Tesla, has remained and spent most of his life, making it hard to pronounce "Teslea"), is considered to be the inventor of the alternating current and uncovered cableless power transmission.
