Atex Motor: Discover an essential range for your applications.

Do you work in an industrial sector such as the pharmaceutical industry, a petrochemical plant, a mining operation, or an agricultural silo? Then you are not immune to risk. This is why well-equipped machinery is essential to protect workers and the environment. In this article, we will explore the ATEX motor, its operation, its advantages, and the equipment on which this type of motor can be used.

The ATEX motor: Operating principle

The ATEX motor is a motor designed to be installed in potentially explosive environments or those prone to flammable substances where gases, dusts, or vapours may be present.

The term "ATEX" stands for "ATmosphères EXplosibles" (Explosive Atmospheres). The operating principle of an ATEX motor remains the same as a standard electric motor. This type of motor is also based on the principle where the magnetic field is created by an electric current flowing through the windings of the stator, the fixed part of the motor. This magnetic field induces an electric current in the rotor, the rotating part of the motor, creating a torque that enables the shaft's movement.

However, the ATEX motor is designed with specific characteristics to ensure safe use in potentially explosive environments.

Advantages and features of the ATEX motor.

The ATEX motor has several specific design elements to ensure motor safety and minimize ignition risks. Here are some advantages of an ATEX motor:

• Explosion resistance: The ATEX motor is designed to withstand an internal explosion and prevent it from propagating externally.
• High sealing: The ATEX motor has special seals to prevent any gas or dust from passing through.
• Anti-spark design: The ATEX electric motor is designed with special materials to prevent the creation of sparks.
• Surface temperature control: This type of motor is equipped with a device that controls the temperature to prevent ignition in explosive environments.
• ATEX Certification: The ATEX motor must be certified according to Directive 2014/34/EU (a product suitable for use in an explosive atmosphere).
• Regular inspections: The ATEX motor must be inspected regularly to comply with safety standards.

Applications and areas of use for ATEX motors.

A: All electrical machinery must bear the CE marking to indicate their conformity with the provisions of all applicable Directives.

B: Identification number of the Notified Body.

C: Electrical machinery subject to explosions must bear the specific EX marking in a hexagon.

D: These are the industry groups: Group I corresponds to machinery intended for use in mines. Group II corresponds to electrical machinery intended for use in different industries where explosive atmospheres may form.

E: The machinery category

• M2 = mines
• 1G = Category 1 for gas (zone 0)
• 2G = Category 2 for gas (zone 1-2)
• 3G = Category 3 for gas (zone 2)
• 1D = Category 1 for dust (zone 20)
• 2D = Category 2 for dust (zone 21-22)
• 3D = Category 3 for dust (zone 22)

F: The type of atmosphere G (Gas) or D (Dust).

Permanent Risk: Zone 0 (Gas) -CE EX II 1 G / Zone 20 (Dust) - CE EX II 1 D

Occasional Risk:Zone 1 (Gas) -CE EX II 2 G (or 1 G) / Zone 21 (Dust) - CE EX II 2 D (or 1 D)

Potential Risk: Zone 2 (Gas) - CE EX II 3 G (or 2 G or 1 G) /Zone 22 (Dust) -CE EX II 3 D (or 2 D or 1 D)
