This paper presents an optimal design method to optimize three-phase induction motor in manufacturing process. The optimally designed motor is compared with an existing motor having the same ratings. The Genetic Algorithm is used for optimization and three objective functions namely torque, efficiency, and cost are considered. The motor design procedure consists of a system of non-linear equati...

In the structure of direct vector control of an induction motor, there are three main sections that have important role in improvement of the induction motor drive operation. This three sections, including: 1- the estimation block of the feedback signals, 2- the block of the  required PWM pulses generation for the inverter unit, and 3- control blocks (usually PI) for generating the require...

LIM-homeodomain (LIM-HD) transcription factors form a combinatorial 'LIM code' that contributes to the specification of cell types. In the ventral spinal cord, the binary LIM homeobox protein 3 (Lhx3)/LIM domain-binding protein 1 (Ldb1) complex specifies the formation of V2 interneurons. The additional expression of islet-1 (Isl1) in adjacent cells instead specifies the formation of motor neuro...

The formation of topographic neural maps relies on the coordinate assignment of neuronal cell body position and axonal trajectory. The projection of motor neurons of the lateral motor column (LMC) along the dorsoventral axis of the limb mesenchyme constitutes a simple topographic map that is organized in a binary manner. We show that LIM homeodomain proteins establish motor neuron topography by...

In this paper the dynamic behavior of linear induction motor is described by a mathematical model taking into account the end effects and the core losses. The need for such a model rises due to the complexity of linear induction motors electromagnetic field theory. The end affects by introducing speed dependent scale factor to the magnetizing inductance and series resistance in the d-axis equiv...

in this research using the theory of induction motor (um), a um with liquid as secondary part is planned and manufactured. the main objective for planning of this motor is to investigate the possibility of chemical liquids pumping such as liquid poison and acids. results of many laboratory tests are shown to conclude that pumping force in the manufactured pump is dependent on many factors su...

LIM transcription factors confer developing axons with specific navigational properties, but the downstream guidance receptors and ligands are not well defined. The dermomyotome, a transient structure from which axial muscles arise, is the source of a secreted long-range chemoattractant specific for medial-class spinal motor neuron axons (MMCm axons). We show that fibroblast growth factors (FGF...

LIM homeodomain factors regulate the development of many cell types. However, transcriptional coactivators that mediate their developmental function remain poorly defined. To address these, we examined how two related NLI-dependent LIM complexes, which govern the development of spinal motor neurons and V2a interneurons, activate the transcription in the embryonic spinal cord. We found that sing...

input frequency is one of the important variables in design and performance analysis of single-sided linear induction motors (slims). changing the frequency changes both the dimension of the slim in design process and the performance of the designed motor. the frequency influences the induced eddy currents in the secondary sheet as well as saturation level of the secondary back-iron. in this pa...

Induction motor is the most popular load in the industry, it is very important to study about the effects of voltage quality on induction motor performance. One of the most important voltage quality problems in power system is voltage unbalance. This paper evaluates and compares two methods including finite element method (FEM) and equivalent electrical circuit simulation for investigation ...
