Comment marche la voiture électrique?

La voiture électrique est un véhicule qui utilise comme alimentation l’énergie chimique emmagasinée et transférée au moteur sous forme d’énergie électrique.

Les premiers prototypes de voiture électrique furent réalisés déjà il y a 200 ans, au cours de la première moitié du 19ème siècle.
Grâce aux révolutions industrielles de...
Comment fonctionnent les roulements? Les types et la durée de vie

Le roulement, c’est un mécanisme utilisé pour réduire le frottement entre deux objets en mouvement rotatif ou linéaire l’un par rapport à l’autre.

C’est Léonard de Vinci qui a eu les premières intuitions en étudiant les frottements.

Mais c’est Philip...
How does a thermal power plant work?

A thermal power plant is a large-sized plant that turns the thermal energy into electric energy, using water as working fluid.
Thanks to their production of electricity we can turn on the lights and make all our household appliances work, so that we can take advantage of many comforts.

The first thermal power plant was built in New York in 1882,...
Solar energy and photovoltaic cells

Solar energy is the energy associated with solar radiation and it represents the primary source of energy on Earth.
The sun is the engine of life on earth, which gives us light and heat.
Its radiation, used by plants to grow, passes in the form of chemical energy to living organisms that eat plants, and to others such as humans who feed themselves with animals and plants. ...
How does a hydraulic and pneumatic cylinder work?

In this video, we will see the major differences between hydraulic and pneumatic cylinders, their functioning, and their applications in the industrial sector.

Before starting, it is essential to specify that there are differences between the single-acting cylinder and the double-acting one.
The single-acting cylinder can be ruled in...
What is an ENCODER - Linear and Rotary encoder - Incremental and Absolute encoder

An encoder is a communication device that controls the motion of an operating device.
Encoders are used to translate rotary or linear motion into a digital signal helping to determine the speed or position of a motor or other moving equipment.
Basically, an encoder acts as a measuring system for moving parts. ...
What is a TRIODE and how does it work?
The importance of the Grid


A TRIODE is an electronic amplifying device belonging to the vacuum tube family.
In electronics, a VACUUM TUBE is a device that controls electric current flow in a high vacuum between electrodes to which an electric potential difference has been applied.

There are many...
How the Internet Works? (Part 2)
Internet’s Undersea Cables - ICANN - Data transfer


In the first part of this video we had the chance to understand how Internet communication works.
Now we are going to see how fiber optic cables are laid on the seabed and how the data finally reaches our laptop and smartphone.

Submarine cables are...
How the Internet Works? (Part 1)

The dynamic, user-friendly interface of the Internet as we know it today, is breathed life into by a multi-layer global network system that connects hundreds of millions of computers.

If you are watching this video, it is because a sophisticated signal transmission system has been developed and implemented over the years.
Most likely the data in this...
Stepper motor (Part 2)

In the first part of the video we had the chance to see the working principle of the permanent magnet stepper motor, as well as the variable reluctance stepper motor.

Now we will focus on the working principle of another type of stepper motor. This is the most commonly used stepper motor type today which combines the features of a permanent magnet stepper motor with those of a variable reluctance stepper...
Stepper Motor (Part 1)

In this video we will see why the stepper motor is considered, among other electric motor types, the ideal choice for all those applications that require maximum precision in angular movements and rotational speed. Stepper motors in fact offer excellent speed control, repeatability of movement and precise positioning.

The same precise positioning required during the operation of this robotic arm, used by JAES...
Comment marche le système de freinage?

Est-ce que vous vous êtes déjà demandés ce qui se passe quand on appuie sur les freins de notre voiture? Dans cette vidéo on va expliquer en détail comment marche le système de freinage d’une voiture.

Le système de freinage le plus utilisé aujourd’hui est représenté par le frein à disque.
...
Comment marche la direction?

Qu’est-ce qui se passe quand on tourne le volant de notre voiture? Allons le découvrir ensemble dans cette nouvelle vidéo, où on va expliquer toutes le fonctions du système de direction.

Une des choses fondamentales d’un véhicule est la possibilité d’aller tout droit ou prendre un virage. Ceci est possible grâce au système de direction, qui bien sûr a la fonction de changer la direction des...
Qu’est-ce qui se passe quand on change de vitesse?

Est-ce que vous vous êtes déjà demandés pourquoi il faut changer de vitesse quand on conduit la voiture? Et qu’est-ce qui cause le bruit ennuyeux quand on se trompe à embrayer?

Dans cette vidéo on va vous expliquer ce qui se passe quand on change de vitesse dans notre voiture, à travers l’explication du fonctionnement de l’embrayage et de la boîte de vitesse...
Qu’est-ce qui se passe quand on tourne la clé de contact dans la voiture? Moteur à combustion interne

What is a screw jack and how it works

A Screw Jack also known as a Worm Screw Jack, is a device used to convert rotational motion into a “push-pull” linear motion. It utilises the property of a screw thread providing a mechanical advantage which means that it can be used to amplify force. The rotary movement can be supplied manually or thanks to the help of hydraulic or pneumatic motors. Or thanks to electric motors, like the induction motor!
