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 research 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.

Induction motors are the most widely used electrical motors due to their reliability,
low cost and robustness. However, induction motors do not inherently have the capability
of variable speed operation. Due to this reason, earlier dc motors were a
pplied in most of
the electrical drives. But the recent developments in speed control methods of the induction
motor have led to their large scale use in almost all electrical drives.
Out of the several methods of speed control of an induction such as pole changing,
frequency variation, variable rotor resistance, variable stator voltage, constant V/f control,
slip recovery method etc, the closed loop constant V/f speed control method is most widely
used. In this method, the V/f ratio is kept constant which in turn maintains the magnetizing
flux constant so that the maximum torque remains unchanged. Thus, the motor is
completely utilized in this method.
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 research is concerned in modeling the problem of sloshing in
moving cylindrical containers in ANSYS program where we model
the problem on a partially filled cylinder then we find the resonant
frequencies in addition to study the interaction between the cylinder
and the fluid.
The Electromagnetic Interference and EMC are one important phenomenon, since the EMI
causes degradation in the performance of electric and electronic instruments.
The EMI- problem may decrease effectiveness of sensitive devices and even may lead to
a
failure of its operation.
This paper studies EMI-problem between different systems by using convenient computer
programs as CST, which provides modulation and simulation of this problem. This method provide
ability to trace and evaluate EMI microscopically in space and real time.
This paper deals with electromagnetic(EM) interaction in anisotropic medium which is characterized by spatial different permitivity in (x,y,z)coordinates. The EM-analysis is a modern method in micro- and nano-scopic technology.
This interaction wa
s modulated and simulated by CST software (Computational System Technology) that confirms the behavior of EM propagation and scattering in an isotropic medium.It could be also used in data transmission, device construction and scattering analysis
