HOW AN ELECTRIC MOTOR WORKS ?

Le moteur électrique est un dispositif électromécanique dont le rôle principal consiste à convertir l’énergie électrique en énergie mécanique, grâce à l’interaction entre le courant électrique et le champ magnétique. Cela crée ainsi une rotation qui alimente une variété d’applications industrielles et domestiques. Tous les moteurs electriques présentent une réversibilité inhérente. Cela signifie qu’ils sont capables de fonctionner dans les deux sens : en convertissant l’énergie électrique en énergie mécanique pour entraîner une charge (mode moteur) et en transformant l’énergie mécanique en énergie électrique lorsqu’ils sont entraînés par une force externe (mode générateur).
Modern electric motors take advantage of the efficiency of permanent magnets to generate precise and consistent motion. Making them essential in many industrial and technological applications.Ainsi, il existe différents types de moteurs électriques : le moteur à courant continu et le moteur à courant alternatif, pouvant être synchrone ou asynchrone. Les moteurs electriques asynchrones triphasés peuvent être alimentés en 230/400v (couplage étoile) ou en 400/700v (couplage triangle). Pour inverser le sens de rotation, il suffit d’inverser deux phases sur le bornier de la boite à bornes.Electric motors, also called induction machines, are a type of machine that works with alternating current, and which does not require a connection between the stator and the rotor.
In the past, the asynchronous motor was in direct competition with the synchronous motor for high power applications. However, with the evolution of power electronics, its position has been consolidated. It is found in various fields such as transport (subways, trains, ships), industry (machine tools) as well as in household appliances. Asynchronous machines are also used as generators, especially in wind turbines.

Elements making up an electric motor:

An electric motor is a complex device made up of several essential elements that work in tandem to convert electrical energy into mechanical motion. The main components of an electric motor include:
  1. Stator: The stator is the fixed part of the electric motor and houses the copper wire windings. It creates a stable magnetic field when electric current flows through it.
  2. Rotor: The rotor is the moving part of the motor and is placed inside the stator. It is also made of copper wire windings, but these are mounted on a rotating axis. When electric current passes through the rotor, it reacts with the magnetic field of the stator to generate the rotational motion.
  3. Collector (for DC motors): DC motors use a collector to reverse the polarity of the rotor windings as it spins. This allows the rotor to continue spinning in one direction.
  4. Switch (for AC motors): AC motors use a switch to reverse the direction of electrical current in the rotor at regular intervals, which maintains rotation.
  5. Levels: Bearings are supporting components that reduce friction and allow the rotor to spin smoothly. They are essential for engine durability and performance.
  6. Box: The electric motor box or enclosure protects internal components from external elements and provides a sturdy structure for mounting.
  7. Connectors and cables: Les câbles électriques et les connecteurs relient le moteur à une source d’alimentation électrique, permettant ainsi la transmission du courant nécessaire au fonctionnement du moteur. On y trouve par exemple les fils de cuivre émaillé (suivez ce lien pour plus d’explications techniques), ou encore des fils de Litz, comme définis ici.
Ces éléments travaillent de concert pour créer le mouvement rotatif nécessaire à de nombreuses applications, allant des ventilateurs aux machines industrielles, en passant par les véhicules électriques. Comprendre la composition et le fonctionnement d’un moteur électrique est essentiel pour tirer le meilleur parti de cette technologie omniprésente dans notre vie quotidienne.

QU'EST-CE QU'UN MOTEUR ÉLECTRIQUE ATEX ?

The ATEX (=ATmosphere EXplosive) electric motor, also known as an explosion-proof motor, is designed for use in potentially explosive or flammable environments. The term "ATEX" comes from the European directive 2014/34/EU, which regulates equipment used in such environments.

ATEX solutions are built in such a way as to prevent any source of ignition that could trigger an explosion, minimizing the risks associated with gases, vapours, flammable liquids or dust. These machines are essential in certain industries. Indeed, we can cite oil and gas, chemicals, pharmaceuticals, petrochemicals, as well as in production and storage sites for potentially dangerous products.

By choosing the ATEX solution, you guarantee the safety of their operations while complying with strict safety regulations in environments at risk of explosion.

LE CUIVRE DANS LES MOTEURS ELECTRIQUES : PERFORMANCE ET DURABILITÉ ​

Copper plays an essential role in the operation and performance of electric motors. Indeed, this metal with excellent electrical and thermal properties is an essential component of the coils and windings used in electric motors.

 

When an electric current passes through these coils, the copper offers a low electrical resistance, which helps to minimize the energy losses by Joule effect, thus ensuring a high efficiency of the machine. Additionally, copper is widely used in the manufacture of magnets, including rare-earth permanent magnets, which are frequently employed in electrical rotating machinery to create the magnetic field needed to convert electrical energy into mechanical motion. .

 

However, the link between copper and sustainability is complex, as the mining and production of this metal can have environmental impacts. It is therefore crucial to consider sustainability approaches, such as recycling copper, reducing its use through more efficient designs, as well as exploring alternative materials and emerging technologies to ensure electric motors continue to perform. move towards more environmentally friendly solutions.

HOW TO CHOOSE YOUR ELECTRIC MOTOR?

Choosing the optimal electric motor is a crucial step for the success of any project requiring electric propulsion. To make an informed decision, it is essential to take into account several technical parameters. First, determine the power required based on the workload, in watts (W) or kilowatts (kW). This will help you select the engine that can deliver the necessary power without oversizing.

Next, the rotational speed of the motor, measured in revolutions per minute (rpm) or radians per second (rad/s), is a determining factor. Make sure it matches the needs of your application. Torque, measured in Newton meters (Nm), is also crucial. It depends on the load to be moved or driven, and it is imperative to select a motor capable of providing the necessary torque while avoiding overheating.

The environment of use is another fundamental aspect. If your application is exposed to special conditions, such as extreme temperatures or high humidity, choose an electric motor adapted to these environmental constraints.

In addition, the supply voltage must be compatible with the chosen motor. Electric motors come in different voltages, such as 12V, 24V, 110V, or 220V, and it is essential to ensure that the supply voltage matches that of the motor.

Finally, consider the durability and reliability of the engine. Look at the IP protection class (Protection Rating) to assess resistance to dust and humidity. Also check the motor specifications for its estimated lifespan, as this can have a significant impact on long-term operating costs.

In summary, choosing the right electric motor involves careful analysis of power, speed, torque, operating environment, supply voltage, durability and reliability. By taking these parameters into account, you will be able to select the electric motor that will best meet the needs of your project, thus ensuring optimal performance and maximum energy efficiency.
