What is Machine?

The machine is a device made up of different mobile and fixed parts that take advantage of the energy it has to perform a specific job. Machines typically contain a motor. These, in turn, are also machines and are responsible for making the machinery work by transforming its energy source into required work. Another component is the mechanisms. These are the mechanical elements with which the artefact is forme. It is the fundamental element to transform the energy that comes out of the engine. Finally, there is the frame, which is the structure that supports the engine.

The explosion of the use of machines occurred in the second half of the eighteenth century in England. When the Industrial Revolution occurred. In addition to being a transforming political. Economic and social process, marked a before and after in the form of the creation of the artefacts. The implementation of the machines had a direct advantage in the time of mass production, which benefited the companies’ income. Still, on the other hand, it was the cause that many people lost their jobs because these mechanisms replaced them.

Examples of uses and Phrases

“That player is a machine, he doesn’t miss a move, and he always scores a good goal”. In this example, the everyday use of the word stands out to refer to how good a person is in a sport.

“My grandfather’s chocolate machine is German and has been in use for 100 years.” In this example, it refers to an artifact that produces a product.

“The engineer pointed out that the train has certain imperfections. That the engine should be adjust because it makes a strange noise.” Here we talk about the machinist. And a part of the machinery that is the engine.

Machine Concept

Machine Concept

The term “machine” that will be handle in this portal is derive from the definition of the “Machines” Directive.

Strictly Speaking, the “Machinery” Directive Defines a Machine as:

“A set of parts or components linked together, of which at least one is mobile, associated for a given application, provided or intended to be provided with a drive system other than human or animal power.”

As an exception to the previous case, a machine is considered when the assembly is intended to lift loads, even though the drive system is human power.

A machine is also consider to be a set like the one define above that only lacks the connection elements to the energy and movement sources and assemblies that can only function after being assemble on a means of transport or install in a building or structure.

Finally, the set of machines of two or more machines or quasi-machines assembled for a specific application is also consider a machine.

In a broad sense, the term machine is also use to refer to other products that. Although not strictly speaking a machine, are include within the scope of this Directive.


Although it may vary depending on the type of machine in question, most machines have the following components: motor (it is the device that facilitates the modification of energy to achieve the work for which the machine is intend). A mechanism ( these are mechanical-type elements that what they do is transform the energy sent by the engine into the desire effect).

Frame (it is an essential rigid structure to ensure the link between all the elements and its mission is to in addition. To support both the mechanism and the motor) and safety components (they do not contribute anything to the work of the machine per se because its mission is to protect the people who work with the machine; at this point and to add to the required safety conditions. It is essential to carry out regular maintenance checks that guarantee the good performance of the machine).

Machine Classes

There are various types of machines to the energy source that moves them to carry out their work. Such as manual machines (this type of machine needs the hand of man to work). Electrical devices (transforms kinetic energy into other types of energy, such as generators. Motors and transformers), thermal devices (these are those that allow the exchange of energy from an axis that causes the intervening fluid to vary its density when it passes through the machine). And hydraulic machines ( It is a type of fluid mechanics that is guide by the properties of incompressible fluids).


On the other hand, the concept is use as a synonym for locomotive. Which is precisely that machine mounted on wheels and has the mission of dragging the wagons that make up a train.

Trains are a vital means of public transport for citizens since they facilitate the transfer of long, medium and short distances and merchandise transfer.


The word machine is a word that presents a regular use in our language since it names the device, artefact. Composed of a set of mechanisms and parts, both fixed and mobile, whose movement allows directing, regulating, or failing that. Changing the energy to carry out a job with a specific mission.
