The first YouTube channel entirely dedicated to spare parts
In our channel we deal with many different topics specific to the area of electronics, mechanics and hydraulics.
We create animated educational video for many manufacturing companies
in which we explain the operation of every industrial device.

What is a submersible pump and how it works

The submersible pump is a particular type of centrifugal pump used to move fluids from one point to another or to favor their ascent to the surface.

This hydraulic device can be used, for example, to empty a flooded area, but also to empty or fill a swimming pool or recover and bring to the surface the water contained in a well.

How does an induction motor works?

An induction motor or asynchronous motor is an AC electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.

Since 1885 Italian inventor Galileo Ferraris had shown that two orthogonal coils, in which alternating currents out of phase by 120 degrees flow, generate a rotating magnetic field.

What is a WIND TURBINE and how does generate electricity? Wind power - Components - Accidents

Wind turbines are devices that convert the wind’s kinetic energy into electrical energy.

We can simply describe the wind as moving air, caused by differences in atmospheric pressure between different regions of our planet.

How do airplanes fly - Bernoulli principle or Coandă effect?

An airliner is typically defined as an aircraft intended for carrying multiple passengers or cargo in commercial service. When the Wright brothers made the world’s first sustained heavier-than-air flight, they laid the foundation for what would become a major transport industry.

Listing every single component of an airplane is almost impossible. The modern airliners in fact are composed of huge variety of mechanical, hydraulic and electronic components.

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!

In this video we will focus on the working principle of the worm screw jack.

Have you ever wondered what happens when you turn the key inside your car ignition?

In this simple video we will explain all the steps involved in this process, from the ignition to the operation of the internal combustion engine.

When you get on your car the first thing you do, after putting the seat belts on, is to insert the key in the ignition switch to start the engine.

How Car Steering Works?

What happens when we turn the steering wheel of our car? Let’s find it out in this video, in which we explain the steering system’s functions.

What’s fascinating in cars is that when we turn the front wheels, all the vehicle will turn in that direction. But why does the car follow a precise curve after steering instead of proceeding in a straight line? To find the answer to this question we need to know the physics of the wheel, one of the greatest inventions in human history.

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 inside its automated video acquisition system.

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 motor. We are talking about of the Hybrid stepper motor.

The World of Engineering
What is really engineering?

Everybody has certainly seen huge buildings while driving, like a suspension bridge, and wondered “how can that bridge hold up? How has it been designed and built?”.

This is what engineering is for: a technical-scientific discipline, whose goal is to produce systems and solutions for technical and material requirements through design and creation of a good or a service, or for the development and control of the industrial process.

What is a diode and how it works - PN junction and 3D animation

The diode is a mainly resistive non-linear passive electronic component with two terminals, whose function is to allow the flow of electric current in one direction and virtually block it in the opposite one.

The two diode terminals are called ANODE and CATHODE. The electric current conventionally goes from the anode to the cathode following this direction.

The Engineering World
Different types of engineering

Over the years, some people are world-known as great engineers because they have given us structures, solutions, methods that even nowadays we consider them as some brilliant innovations. If you think of the engineer Brunel who built the Great Western Railway in the United Kingdom, and still working today, or Archimedes recognized as the greatest of all classical engineers, with his screw pump also called the screw of Archimedes.

All great engineers were and are astounding in many areas, but most operate within well-defined specializations, each with its own characteristics and expertise.
