إن المضخات الغاطسة عملياً مستخدمة استخداماً واسعاً لضخ المياه و استخراجها من الآبـار، و هذه المضخات تكون مقادة بواسطة محركات تحريضية ذات قفص سنجابي، إذ إنَّ المضخة تكون مرتبطة بشكل مباشر مع المحرك التحريضي الذي يقودها و يكونان بذلك مجموعة تسمى مجموعة محرك مضخة أو المجموعة الغاطسة. من الناحية الاقتصادية فإن تكاليف حفر البئر يتناسب طردياً مع قطر فوهة الحفرة، و من ثَـمَّ فإن التكاليف سوف تنخفض انخفاضاً ملحوظاً كلما كانت أبعاد المجموعة الغاطسة صـغيرة، من هذا المنطلق سوف نقوم في هذا البحث باختبار إمكانية تصميم محرك تحريضي غـاطس يعمل بتوتر ذي تردد [HZ [ 150 =f بحجم أصغر و بسرعة مساوية ثلاثة أضعاف المحـرك التحريضي الذي يملك الاستطاعة نفسها و يعمل بتوتر ذي تردد [HZ[50 =f و بحيـث تكـون المحددات الأساسية للمحرك المصمم ليست أسوأ من المحرك ذي التردد [HZ[50=f .
The deep-well pumps are practically and widely used to pump water up from wells. These pumps are driven by squirrel-cage induction motors where the pump is directly connected with the induction motor it drives. They form a pump-motor set or a deep-well set. Economioally, the cost of digging a well proportionates with the diameter of the hole opening. This diameter is related to the deep-well set dimensions. Whenever the dimensions of the deep-well set are small, the cost of digging a hole will be notably less. From here, in this research we shall test the possibility of desiging a deep-well induction motor with a voltage of f =150 Hz frequency in a small size. and in trifold speed of the induction motor which has same power and functions as the motor with a voltage of f = 50 Hz frequency and where the essential parameters of the motor aren’t worse than the motor with f = 50 Hz Frequency.

The research was
depended on the concept of Partial Relative Indicators (PRI) for the
resulting harmonics as a new way to detect the fault through
determination of relative indicator PI of each type of harmonics that
result during the operation of motor at the different loads.
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 a study aimed at improving the performance of the machine, hot steel rolling, and make them conform to international standards, where the study includes two phases: the first includes mathematical modeling and simulation programmi
ng language with a rolling machine. The second phase will include the development and testing of alternative control systems.
I tested the validity of this model through analyzes of performance curves derived from simulated and compared with the values of the curves and tables station real taken from the HSRMP. Through ensure this form to the parameters of the system characteristic variables representing the performance of the real station, this makes it a useful tool allows simulation of plant performance, explain the behavior of variables The test cases in addition to the possibility of change work and operating strategies to improve the overall operation. From this model performed the initial analysis, which proved the possibility of improving the performance of the station to implement the following modifications:
• Reduce the value of hard integrative models associated with the rings are positioned in the final stage.
• unification of all evil ratios for nutrition workshops.
• Revolving transfer is located in the last phase .
Note: HSRMP ( Hot strip rolling Mill plant ) .
An attempt has been made to present a brief historical highlight of the role
that mathematics played in the advancement of computer science, and the role
of the latter in the enrichment of mathematical sciences and the solution of
well-known problems that posed a challenge for centuries. This interaction has
been a motive that contributed to the advancement of both branches of
knowledge.
In this paper the control system of the switch reluctance motor ( SRM ) has been studied and executed, and driven by computer through the printer parallel port (LPT), and a simple explanation for switch reluctance motor has been introduced also it's
work principle and some of its advantages and disadvantages with presenting some samples, where suitable electronic circuits, pulses generation circuits, isolation circuits between computer and power circuits has been executed, with suitable programming for controlling the whole system, then suitable measurements for monitoring have been done like currents, voltages, motor speed and recorded to be discussed.
