In this paper, the development of the drive system of the motor Wire port Crane according to the principle of the indirect field orientation. Require the operation of the port Crane operations, different operation situations of variable speed and Torque with time, which is a case dynamic electro and electro-magnetic transient, may affect the performance of operations, so therefore been building motor Wire port Crane operations system corps in winches achieve: - High performance and Efficiency. - Build the desired control system according to the principle of the Pulse Width Modulation (PWM) and the main power system, taking into account the reduction of changes DC-Link voltage and achieve maximum flux before starting the motor. - Reduction of excess Voltage that may appear on a DC-Link, using the brake Transistor with Brake resisters. At the end of the research has been reviewed and the search results that indicate the outstanding performance of the proposed system with the ability to use the same system to run automated processes different.
The purpose of research is to build a model of the electric driving system for threephase squirrel-cage induction motor using oriented electric field method so as to control both the speed , flux and current, ( PI ) controllers was used . The mach ine model has been formed based on the equations of the machine written in the stationary coordinates . To complete the process of control without measuring the rotor flux , a model of flux from the measured values of stator current and rotor speed was build, and it can be measured directly .
This paper presents an analytical and laboratory study of the behavior and evolution of the symmetrical components of both voltage and current of a three-phase induction motor as a function of the load torque applied to it and to increasing in the imbalance which effect the electrical grid. The effect of unbalanced voltages in the voltage source will be also examined on the distribution of motor currents in the three lines and on its performance.
The present research shows the possibility of improving the factor that regulates the relative potential of the three -Phase Non-Salient-Poles Synchronous Generator by Reducing the Flux Leakage Reactance of fixed coil of the stator, at a fixed ai r gap and the out-put data. We proved that the flux-leakage reduction at these conditions,leads to increase the generator circumspection stability,and possibility of the coil-volume excitation reduction. This reflexes the reduction of the generator price at the same out-put data,instead of the ordinary method to rise the stability of the synchronous generator and the potential regulation-factor by the air-gap volume increase. We used the log-method to outline the relative potential regulation factor calculation depending on the practical map of the tension of the synchronous generator,considering the magnetic saturation and drawing the curves of the relative potential regulation and the stability factor by changing the leakage percentage reactance, the (S.C.R.) circuit, and the percentage change of the excitation coil cross-section(A2%),through changing the relative potential regulation .
The study of electromagnetism in electrical machines is critical, especially in the field of design, investment and optimal performance. To achieve this, there are many ways in which varying degrees of accuracy . The main aim of this piece of resea rch is to study electromagnetic fields distribution in 3ph-induction machines using computational numerical methods and proper software, because these fields form the basic principle in machine 's work. It has been used the finite element method aided computer to solve magnetic equations (Maxwell equations). The simulation of magnetic field in induction machine performed by ANSYS-software. The paper shows technique for finding the electromagnetic fields distribution in all parts inside 3phinduction machine to get optimal design.
