Electrical Power and Machines


Electrical Power and Machines, this field became known in the late nineteenth century after the spread of telegraph and power supply stations. Now, this field covers a number of sub-topics, which include energy, electronics, automatic control systems, signal processing, and wireless communications.


It is safe to say that electrical engineering may or may not include electronics engineering. It can be distinguished between them as electrical engineering is concerned with matters related to high-voltage electrical systems such as power transmission and motor control, while electronics engineering deals with the study of electronic systems of low standards (low current - low voltage), and this includes computer science and integrated circuits.


Electrical Power and Machines: Electrical engineering studies and designs many different electrical and electronic systems, such as electrical circuits and generators, motors, transformers, UPS, magnetic materials, and other electromagnetic and electromechanical devices.


Electrical engineering majors

The classic division of electrical engineering was high-voltage current engineering, which today is known as power and motor engineering, and the other, low-voltage current engineering, which evolved into telecommunications engineering. In addition, new engineering fields have been created within the framework of electrical engineering, including measurement engineering, control, and electronics engineering, and biomedical engineering.


With time and the increase in development, each of these branches added many new fields, and in our day it has become difficult to dispense with electrical equipment in most areas of life.


The following sections are not necessarily branches of electrical engineering due to the difference between the university system in both the United States of America and Europe, but these majors have a relationship in one way or another with electrical engineering, and it is one of the most popular fields of engineering.


Energy engineering

Energy engineering is concerned with the production, transmission, and transformation of electrical energy by designing devices such as transformers, generators, and electric motors. Most of the world's governments distribute electricity by building power stations with generators. These generators generate electrical energy and then distribute it to consumers. Electrical engineers design and maintain power stations.


Engine engineering

Motor engineering converts electrical energy by electrical machines (electric motors) into mechanical energy.


Motor engineering is of high importance for automation technologies since many mechanical motors are electrically driven. Electronic engineering plays an important role in the framework of engine engineering, on the one hand in the field of motor control, and on the other hand in the field of electronically reducing consumption.


The well-known electric motors operate on the use of two electrodes and a central pillar, so the pillar begins to rotate when the poles are opposite to each other.


Communications Engineering

With the help of communication engineering, information is transmitted by electrical impulses or electromagnetic waves from the transmitter to one or more receivers. Among the interests of telecommunications engineering is the delivery of information with the least amount of data loss, as well as signal processing systems such as encryption, decoding, and purification, and is considered one of the studies expected to affect the future of energy in the world.


electronic Engineering

Electronic engineering is concerned with the development, manufacture, and uses of electronic components such as a capacitor, inductor, and semiconductor elements such as diode and transistor.


Microelectronics, one of the branches of electronic engineering that is concerned with developing integrated circuits (IC) from semiconductor materials. An example of an integrated circuit: microprocessors.


The capacitor and coil are not electronic parts but rather electrical parts. Nevertheless, they are an important part of the configuration of electronic circuits such as resonant circuits used in transmitting and receiving, electronic matching circuits, and analytical networks.
