تم في هذا البحث بناء نموذج لنظام قيادة كهربائي يستخدم محرك تحريضي ثلاثي الطور ذي دائر مقصور باستخدام طريقة الحقل الموجه و ذلك للتحكم بكل من السرعة، الفيض و التيار. تم استخدام منظمات تناسبية تكاملية في دارة التحكم، أما نموذج الآلة فتم تشكيله بالاعتماد على معادلات الآلة التحريضية المكتوبة في الإحداثيات الثابتة. لإتمام عملية التحكم دون قياس فيض الدائر تم بناء نموذج للفيض انطلاقاً من القيم المقاسة لكل من تيار الثابت و سرعة الدائر التي يمكن قياسها بشكل مباشر و تم التحقق من النموذج بنتائج تم الحصول عليها باستخدام بيئة Matlab-Simulink.
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 machine 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 .

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.
Due to scientific and technical advances in industrial electronics, SRMs have become one of the most attractive motors in recent decades.
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.
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 simplified dynamic mathematical model of hybrid stepper motor was studied in this
research. The aim was to simplify the study and to concentrate on certain topic of this subject.
The mathematical model which describes their mechanical and elect
rical dynamic behavior of
the mentioned motor was done. Whereas, the mechanical model can be derived by Newton law,
and electrical model can be derived by Kirchhoff law depending on the electrical equivalent
circuit to each phase.
