Using a Servo Motor in an ATEX Environment
What are the main ATEX guidelines, and in which environments are they important? In this article, we will discuss the ATEX guidelines, ATEX environments, and finally the application of servo motors in these environments. The safety of personnel is of utmost importance, and with the ATEX guidelines, you ensure an environment that is safe from explosions.
ATEX Environment
An ATEX environment refers to a setting where explosive or flammable substances can be released. These substances can become flammable due to the presence of combustible materials such as gases, vapors, mists, or dust particles. It’s crucial to implement the appropriate safety measures in such environments to eliminate the risk of ignition and explosions.
An ATEX servo motor is essential for environments such as the oil and gas industry, chemical and petrochemical sectors, energy sector, or pharmaceutical industry because they are specially designed and certified to operate safely in potentially explosive atmospheres. These motors comply with ATEX guidelines and possess features that ensure safety. They are engineered to prevent generating ignition sources that could cause an explosion. Additionally, these servo motors provide increased protection against sparks and explosions. They are equipped with special enclosures and seals to prevent combustible substances from infiltrating the motor. Moreover, they utilize materials resistant to corrosion and chemicals commonly found in ATEX environments.
Despite the stringent safety standards, ATEX servo motors still provide the precise positioning and reliable performance required for industrial applications. They ensure precise control of movement, which is essential for optimizing processes and enhancing productivity.
ATEX Guidelines
The ATEX guidelines consist of specific regulations that apply to equipment used in potentially explosive atmospheres. There are two main directives: ATEX Directive 114 (for manufacturers) and ATEX Directive 153 (for employers).
ATEX Directive 114
The ATEX Directive 114 sets requirements for the equipment itself. To be ATEX-certified, servo motors must adhere to strict safety standards and criteria. They need to be intrinsically safe, meaning designed not to generate ignition sources, and they must be capable of withstanding explosive atmospheres. Additionally, they must comply with specific protection levels and classes, such as IP protection ratings and temperature classifications.
ATEX Directive 153
The ATEX Directive 153 pertains to workplaces and mandates that employers take appropriate measures to ensure the safety of employees in potentially explosive environments. This includes the use of ATEX-certified equipment, such as servo motors, that meet the requirements of the ATEX Directive 114.
Only servo motors that comply with these ATEX guidelines and have obtained the necessary certification can be safely and legally used in potentially explosive atmospheres. This certification is crucial to ensure safety and minimize the risk of ignition and explosions.
ATEX Servo Motors Type EX and EY for Explosion Safety
When precise mechanical movements are required within an ATEX zone, special servo motors suitable for use within this ATEX zone can be utilized.
The EX and EY series of brushless AC servo motors provided by VARIODRIVE are specifically designed for use in hazardous environments. Equipped with robust explosion-proof enclosures, these servo motors are capable of containing internal explosions without posing a risk to the surrounding area. There are two versions available, compliant with North American or European safety standards. The EX and EY servo motors offer high torque and a wide speed range. Additionally, various winding options and numerous features are available for maximum flexibility. Furthermore, these servo motors can be equipped with special ATEX planetary gearboxes and linear spindle or belt units, which are also certified for use within an ATEX zone.
ATEX servo motors are applied, for example, in:
- Graphic machinery
- Paint spraying equipment
- Plastic processing machinery
- Chemical, petrochemical, and pharmaceutical industries
- Waste processing facilities
- Food industry
