Early 1830 Faraday worked on the process that is related to electromagnetic fields. He discovered a theory that is basic behind the working of a generator. Later several discoveries have been done that led to the invention of some other generators, those are the shunt, series, and compound type. However, all these types work on the same principle I,e the Faraday's law of electromagnetic induction. So, the invention of the magnetic laws by Faraday behind … [Read more...]

How to Make a DC Motor – How a Generator is Made from it
The electric motors first developed were of electrostatic in nature. This type of motor is first invented by Scott scientist Andrew Gordon and Benjamin Franklin in the early 1740s. Later many investigations have been done to improve the performance of the electric motor. In 1821 Faraday invented the rotator motion by the induction principle. Later this rotator motion is considered to be the principle of electric motors. In this article, we shall discuss … [Read more...]
DC Series Motor – Working Principle, Speed Control & Applications
In the early 1870s, the electric motors used in traction did not give profitable results. But the invention of the series motor had brought much convenience in this field. Due to its performance that it can produce high starting torque. This advantage of producing high starting torque is also used the railways where the locomotives can be easily moved forward. In time, a process has also been discovered to use the technology regenerating power by the use … [Read more...]
Testing Methods of DC Machines – Direct and Indirect
In the early 1880s Oslen proposed to test the machine to invent some new and improvements in machines. In his proposal, he highlighted the difficulties he faced running any machine. Accordingly, he also proposed certain measures to be taken to avoid such difficulties. He suggested testing the machines to improve their performance and working difficulties. So, this is the reason why a machine is tested by different methods to know its behavior. There are … [Read more...]
What is PMDC motor – Construction, Working & Applications
The first motor based on the permanent magnet was first invented by Hungarian scientist Istvan. He invented the first PMDC that works on the usage of permanent magnetic field interaction. But these motors faced several constraints to work practically. In 1882, John Urquhart suggested using electromagnets instead of permanent magnets. Early twentieth-century, the permanent magnets secured much importance because of the invention of these magnets made of … [Read more...]
What is BLDC Motor – Construction, Working & Applications
There were brushed motors before the invention of brushless motors. The first brushed DC motor was invented by a German scientist Ernst Werner Von Siemens in 1856. Because of the difficulties that we are facing by the usage of brushed motors since it is less efficient and requires more maintenance. Keeping these difficulties in mind a brushless motor has been invented by T.G. Wilson and P.H. Trickey in 1962. The invention of this brushless motor led to … [Read more...]
Derive the Torque and Power Equation of a DC Motor
The motor was invented by Michael Faraday who discovered the laws of electromagnetic induction. Actually, the invention began with the discovery of Direct current. This invention led to conduct detailed experiments for the invention of the motor. Earlier direct current was developed in 1800 and further investigations have been made for better utilization of DC. This DC helped in investigating the current supplied to the machine to operate. At the same … [Read more...]
DC Generators : Working, Types & Its Applications
Generally, the generator is an electrical device and the designing of this device can be done by observing the dynamo working principle. Thus, we can say that the generator was progressed from the dynamo invention. The dynamo working is also the same as that of a generator and it was discovered by Hippolyte Pixii in the 1830s. In fact, in a dynamo, the AC (alternating current) is supplied to the armature winding and it is converted through a commutator. … [Read more...]
What is a DC Shunt Motor – Definition, Characteristics & Speed Control
The very first experiments conducted for the invention of the motor are done by Andrew Gordon a Scottish scientist and Benjamin Franklin in the early 1740s. This invention required the usage of current and voltage for its operation. Later, the invention of battery by volta in 1799 made possible the invention. This also required the interaction of forces to develop a rotating magnetic field. Later, by the invention of Faraday's law of electromagnetic … [Read more...]
Characteristics of a DC Motor – Shunt, Series, and Compound Motor
Thomas Davenport invented the first real motor later Micheal Faraday and Joseph supported his work. Micheal Faraday did his work mostly related to the working of electromagnetic fields. This invention became the basic principle behind the working of an electrical motor. Beyond the invention of motor further investigations have been done to study the different types of motors such that different motor operations have been discovered. The operation of … [Read more...]
