The initial and commercial type of signal generator was invented in the year 1928 where it supports a frequency range of 500Hz - 1.5 MHz and in April 1929. The initial commercial frequency standard type signal generated was promoted by General Radio with a supporting frequency of 50 kHz. Coming to the first application of this device, an HP 200B audio kind oscillator was used for the calibration of Disney’s breakthrough stereo sound systems that were … [Read more...]
What is a Thermoelectric Generator : Working Principle & Its Applications
The thermoelectric generator is a device, where electric energy is produced directly from heat energy. They are also called Seebeck generators since they used the Seebeck effect to produce power. In conventional power plants, like thermal power plants, nuclear power plants, fuel is used to heat the water. Generally, coal is burnt in that process. After the water starts boiling, and converted into steam, at high pressure, this steam is used to rotate the … [Read more...]
Know the Differences between DC Shunt Motor & DC Shunt Generator
In the scope of electrical technology, a parallel circuit is described to be shunt. Direct current motors and generators where the armature and field windings are parallelly connected are termed as DC shunt motors and DC shunt generators. Fundamentally, a similar machine can be utilized as motors and generators. The foremost variation in between these devices is that in the DC shunt motor the input is of electrical energy and the output is mechanical … [Read more...]
What is a Steam Turbine : Working, Types & Its Applications
Steam turbines are available from the past 100 years and these are manufactured and used in different plants like the combined cycle, fossil power, nuclear plants. The first steam turbine was designed in the year 1884 by Sir Charles A. Parsons. This turbine was simply generated 7.5 KW of energy and used in Newcastle, England for lighting an exhibition. At present, steam turbines can generate above 1,000 MW of energy which is used in major power plants. The … [Read more...]
What is an Excitation : Types and Its Working
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 is Piezoelectric Generator : Circuit Diagram and Its Working
One might surely come across the situation of power supply either they are in the inadequacy of power or difficulty with power generation. Based on the principle of energy conversions, these piezoelectric generators deliver many advantages in multiple applications and industries. As piezoelectricity moves with the concept of conversion of energy from one form to another, generators also work on the same. But, what does a combination of piezoelectricity and … [Read more...]
What is Synchronous Generator : Construction, Working & Its Applications
In the previous article, we have discussed the DC generator which works on Faraday’s law of electromagnetic induction. Similarly, the asynchronous motor also works on the same principle but the only difference is, this generator gives a 3-phase AC output voltage from stator windings whereas the DC generator gives the output like a DC or a single DC. The first synchronous generator was used in the year 1870 when the arc lamp was invented by P.N. Jablochkov … [Read more...]
What is a Stator : Construction and Its Working
At present, the development in motor performance has been increased, particularly with the enhancement of materials employed in motors. Additionally, improvement in performance is provided with the help of optimization techniques for the stator & rotor. The stator is an essential part of electrical machines that can be found in electric motors, generators, biological rotors, mud motors, and sirens. The flow of energy through a stator will be from the … [Read more...]
Free Energy Generator : Working & Its Applications
The first generator was invented early in 1832 by Hippolyt Pixii which was called a Dynamo. It was the first machine that is capable of generating power. Earlier to the invention of the electric generator, the machine introduced was able to work on the basis of the electrostatic principle. This was based on the working of electrically charged plates which is used to drive belts, plates, and disks. As moving forward, the thought of inventing the free energy … [Read more...]
