IE EFFICIENCY CLASSES
An international standard has been established with the aim of classifying the energy efficiency on an international level (IE) of low voltage three-phase asynchronous motors. This is the standard IEC /EN 60034-30.1.
This standard defines the different yields as follows:
- IE1 = Standard efficiency
- IE2 = High efficiency
- IE3 = Premium efficiency
- IE4 = Super premium efficiency
The EcoDesign EuP directive (2005/32/EC) sets out ecodesign requirements for energy-using products. This is Commission Regulation (EC) 640/2009 which specifies the efficiency requirements for electric motors and which introduces in all countries of the European Community the obligation of the minimum efficiency level IE2 from June 16, 2011. Higher minimum efficiencies will be made mandatory in the near future. IE3 efficiency will gradually become mandatory between 2015 and 2017. The regulation applies to three-phase squirrel cage motors at a speed of 50 Hz or 50/60 Hz in the power range from 0.75 kW to 375 kW in 2, 4 or 6 pole versions designed for continuous operation S1. Engines intended for exclusive sale outside the EU may still be supplied after June 16, 2011 with a lower efficiency level. The country of destination must be specified in the order.
HOW AN ELECTRIC MOTOR WORKS ?
The electric motor is an electromechanical device whose main role is to convert electrical energy into mechanical energy, through the interaction between the electric current and the magnetic field, thus creating a rotation that powers a variety of industrial and domestic applications. . All electric motors have an inherent reversibility.
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, on distingue de différents types : 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:
- 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.
- 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.
- 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.
- 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.
- Levels: Bearings are supporting components that reduce friction and allow the rotor to spin smoothly. They are essential for engine durability and performance.
- Box: The electric motor box or enclosure protects internal components from external elements and provides a sturdy structure for mounting.
- Connectors and cables: Electrical cables and connectors connect the motor to an electrical power source, allowing the transmission of current necessary for the motor to operate. For example, we find enamelled copper wires (follow this link for more technical explanations on enameled copper wires), or even the Litz wires, as defined here.
These elements work together to create the rotating motion needed for many applications, from fans to industrial machines to electric vehicles. Understanding the composition and operation of an electric motor is essential to get the most out of this technology that is omnipresent in our daily lives.

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.
