Design and Simulation of IRFOC for SPWM Inverter-fed Induction Motor Considering Core Loss and Stray Load Loss
Abstract: The principle of field oriented control (FOC) or vector control (VC) of induction motors (IMs) is based on the control of both the magnitude and the phase of each phase current and voltage to achieve the decoupling control strategies between flux and torque. To control the flux and the torque precisely based on the FOC, core losses (CL) and stray load losses (SLL), which are generally neglected, should be considered …

Design and Simulation of Fuzzy Logic Based Speed Control for an SPWM Inverter-fed Induction Motor Taking Core Loss and Stray Load Losses into Account
Abstract: Speed and torque of an induction motor need to be controlled in order to achieve smooth control application. Field oriented control aids this factor and enables independent control of speed and torque by establishing an independent relationship between motor parameters. This complex relationship is developed due to consideration of core loss and stray load loss while modeling an induction motor. These two negligible but important parameters are neglected in most …

Molebdate as Corrosion Inhibitor for Aluminium 356 In Acidic and Saline Media
Abstract: Corrosion processes are the cause of significant losses in industry. Organic, inorganic, and mixed material inhibitors have all been used to resist corrosion for a long time, but the environmental toxicity of organic corrosion inhibitors has driven a quest for inorganic corrosion inhibitors. The effect of molybdate as a new corrosion inhibitor on the corrosion of aluminium 356 in acidic and saline conditions was investigated using electrochemical and weight loss …

Influences of Surface Modification of Vetiver Fiber Reinforced Polypropylene Composites
Abstract: Plant-drive vetiver fiber (VF), a significant lignocellulosic fiber, can be included in polymers like polypropylene (PP) in dissimilar ways for attaining preferred features and structure. But its high levels of moisture absorption, poor wettability and inadequate adherence between the fiber and polymer matrix result in debonding with age. To develop the overhead attributes,adequate surface modifications are essential. In our current work, the VF surface was modified by mercerized treatment (MVF), …
