Basics of Electricals

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 has 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...]

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...]

The first motor I,e 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 high-quality … [Read more...]

Though there were brushed motors before the design of brushless motors. The first brushed DC motor was invented by a German scientist Ernst Werner Von Siemens in 1856. The challenges involved in the usage of brushed motors are high as it is limited effective and requires higher sustenance.  Keeping these challenges in understanding a brushless type has been invented by T.G. Wilson and P.H. Trickey in 1962. The contrivance of this brushless motor led to the … [Read more...]

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...]

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...]

The very initial investigations led to the design of the machine are done by Andrew Gordon a Scottish scientist and Benjamin Franklin in the initial 1740s. This discovery required the usage of current and voltage for its development. Later, the contraption of battery by volta in 1799 made possible the design. This also required the cooperation of forces to produce a rotating captivating field. The cooperation of two forces is made possible to create a … [Read more...]

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 these … [Read more...]

Generally, at the beginning of the motor invention, there is a lot of contribution from various scientists. So, the scientist like "Michael Faraday" was invented the various electromagnetic induction laws. In the same way, both the scientists like "Thomas Davenport" as well as "William sturgeon"  were invented the commutator type working machine. The inventions of these three scientists led to DC motor development. There are different types of motor … [Read more...]

An electrical motor is one kind of machine, used to convert one form of energy to another like from electrical to mechanical. These motors are categorized into two types based on the input supply. For instance, if the given power supply is a DC then, then it is called a DC motor. Similarly, if the given input power supply is an AC one, then it is called as AC motor. This article discusses the difference between ac motor and dc motor. Difference between AC … [Read more...]
