Excitation, the literal meaning is different in each stream of science and humanity. It is an increased activity of cells/organs in biological science in chemical science it is increased activity of various molecules and so on. In electrical engineering, the magnetic effect of current and its field which is known as excitation and only after an electrical machine gets excited it is ready to perform other functions like rotation/motoring or generation, etc. … [Read more...]
What are Electrical Conductors : Types and Their Properties
In the period of the 18th and 19th centuries, the concept of electrical conduction took place. And in the scope of electrical and physical engineering, conductors are most necessary to generate the current flow. The concepts of conductors, insulators and electric field came up with the thoughts and experiments done by many scientists and the person who stood behind the invention of these was Stephen Gray in the year 1734. From then the theories such as … [Read more...]
What is an Electric ARC Welding : Principle, Types & Applications
The concept of welding starts from the ancient time itself where the fundamental process is to join two metal pieces. With the development of technology, there was an enhancement in the welding technologies also. In the initial days of the 19th century, there happened a great revolution in the domain of welding and it was using heat resources for the welding process. Especially, welding technologies gained prominence at the time of welding requirements in … [Read more...]
What is a Screw Pump : Working Principle, Types and Benefits
When compared to centrifugal pumps, positive displacement pumps are the most effective ones and screw pumps come under this classification. It came to know that conventional kinds of screw pumps were in availability in the ancient period itself. Then after the screw pump was pioneered by Archimedes. The pumps that were invented initially consists of a cylinder, a revolving unit, and a spiral tube. With the advancements in technology, the operating … [Read more...]
What is a Gear Pump : Design, Working Principle and Types
Pumping industry became extensively prominent from 1982 itself and there onwards there have been multiple enhancements and inventions. One of the developments which stood as the great invention is positive displacement pumps and their types. Enhanced environmental knowledge gave a real development to pumps having no shaft seals. The trend of electronics and computers even entered into the scope of pumps in the aspect of variable speed drives. Pump choosing … [Read more...]
What is Resistance Welding : Types and Their Principles
In the prehistoric period, the scope of welding was forge welding where this process follows up with metal heating and then brazing. But, the enhancements and innovations of technology have shown development in the era of welding that by the end of the 19th century, people became more modernized and their welding techniques also adapted to the change. Arc welding, resistance and gas welding are the fundamental welding techniques employed in many … [Read more...]
What is an Asynchronous Motor : Construction and Its Working
An asynchronous motor is a most extensively used motor in the industry, It is almost impossible to think of an industry without using this motor, due to its operation at the sub-synchronous speed it is known as an asynchronous motor. Having assumed such an important role it becomes imperative to study it in detail. This article discusses an overview of the asynchronous motor like its definition, working, construction, differences, and applications. What … [Read more...]
What are Welding Joints : Types and Their Benefits
These days, metal fabrication is the most popular metal soldering technique, implemented in many industries, but these fabrication techniques are not achieved without welding. So, welding has been around with us from the ancient period itself. The ancient period of welding involves the hammering of two metal pieces under heat until they are connected. The initial and modern welding method was invented by Sir Humphry Davy where an electric arc is generated … [Read more...]
