Let us first understand what is a synchronous motor basically, it is an induction motor that rotates at a synchronous speed. Here again, the question arises what is synchronous speed, now the synchronous speed is the speed at which the magnetic field rotates, depending on the frequency. From the formula Ns=120f/p, we know synchronous speed depends on frequency and number of poles (Ns=synchronous speed, f=frequency and p=number of poles). Practically all … [Read more...]
What is Pump Cavitation : Causes and Its Solutions
Initially, the speculation of cavitation was known in the period 1754 by Euler and later on the solution to this was presented by Henry Besant in 1859. Thornycroft and Barnaby were the persons who observed the scenario of cavitation on the behind sides of propeller blades. In the context of engineering, pump cavitation is the concept that has to be considered in a high priority, because when it left unobserved, there are chances of the machine getting … [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 Three Phase Induction Motor : Construction, Working & Applications
As the name suggests, an induction motor is a combination of induction and motor, induction is influencing or altering in any way an article or object by another article or object without physical contact. The best example being, a magnet that can either attract or repulse without physical contact. The motor is known to be associated with motion. Therefore when we say induction motor it is a rotating device based on the principle of induction. This article … [Read more...]
What is a Diaphragm Pump : Working Principle & Its Applications
Pumps have a long period of history and they were into existence from 2000 B.C. To fetch water, the initial tool that was invented was called shadoof. Even it does not function in the mechanical approach, it was widely accepted by many and best serves the pumping activity. The construction of all these stood as the basis for the development of diaphragm pumps and they were into the market from 1854 onwards. The basic invention of the diaphragm pump was … [Read more...]
What is DC Servo Motor : Principle and Its Applications
A DC motor along with servomechanism (closed-loop control system) acts as a servo motor which is basically used as a mechanical transducer in the automation industry. Based on its accurate closed-loop control, it has versatile applications used in many industries. The DC servo motor definition is, a motor that is used in servo systems is known as a servo motor. A servo system is a closed-loop system where the feedback signal (position, velocity, … [Read more...]
What is a Potential Transformer : Working Principle & Its Applications
In recent past, electrical systems and its generation, transmission, and distribution have occupied the more substantial part of the technology, administration, economic mechanism, and industry sector. The major areas of its utilization include the commercial sector, industries, transport, fishery, and so on, where higher voltage from the power generation substation and distribution systems should be converted to device rating voltages. It involves … [Read more...]
What is a Motor Winding : Design and Its Connections
These days human life is completely revolving around machines and technology. Advancement of technology has shown invention for multiple kinds of machines. And an electrical machine is the one which is crucial to transform one form of energy into another form. So, a machine will generate the output when there is a connection between the electric current and the magnetic field and this connection happened through coil windings. Motor windings hold utmost … [Read more...]
What is a Centrifugal Pump : Types, Working and Specific Speed
Till the 17th century, there were no centrifugal pumps, but you might wonder how people used to transfer liquids. Before the invention of centrifugal pumps, there were mud lifting machines which were almost in portrayal to that of these pumps. But, few of the complications in mud lifting machines turned people’s attraction towards the implementation of centrifugal pumps. Centrifugal pumps are considered as the archetype of process pump spares applied with … [Read more...]
