ABB Hazardous Area Motors

In various industries, from petrochemical plants to mining operations, there exists a need for electrical equipment that can operate safely in hazardous environments. Standard electric motors are not designed to withstand the potentially explosive atmospheres and harsh conditions found in these areas. That’s where ABB’s range of hazard-proof motors come into play. These specialised motors are engineered to meet strict safety standards and regulations, ensuring reliable operation in potentially dangerous locations.

What are hazardous area motors?

ABB hazardous area motors are electric motors specifically designed and certified for operation in hazardous or potentially explosive environments. These environments can include locations with flammable gases, vapours, dust, or fibres, where the presence of even a small spark could lead to catastrophic consequences. Regular electric motors do not possess the necessary protective features to mitigate these risks, making hazardous area motors a vital choice for safety and reliability.

Key differences between hazardous area motors and standard electric motors

Motors designed for hazardous areas are constructed with robust materials and design features to withstand the harsh conditions of their operating environment. They are often built with corrosion-resistant enclosures to prevent deterioration from exposure to chemicals, moisture, or dust.

Perhaps the most critical difference is that these motors are explosion-proof. They are designed to eliminate or contain any sparks, arcs, or heat generated during operation. They achieve this through methods such as increased enclosure strength, flame paths, and encapsulated components, ensuring that any potential ignition source is effectively managed.

Compliance with Industry Standards:

Motors for hazardous areas are rigorously tested and certified to meet international safety standards and regulations. These certifications, such as ATEX, IECEx, or NEC, ensure that the motors comply with the specific requirements for operation in hazardous areas, including temperature, pressure, and material compatibility.

Enhanced Cooling Systems:

In hazardous environments, controlling the temperature is crucial to avoid overheating that could ignite flammable substances. Motors designed for hazardous areas often feature enhanced cooling systems to ensure safe operating temperatures, even in the presence of surrounding heat.

To prevent the ingress of hazardous substances, these motors have robust sealing and gaskets to maintain a hermetic seal. This design feature ensures that no flammable gases, dust, or liquids can penetrate the motor enclosure.

Mining Industry

Redundant Safeguards:

ABB motors for hazardous areas may incorporate multiple layers of protection, such as redundant sensors and emergency shutdown systems, to further enhance safety.

These motors are used in applications across a wide range of industries, including:

  • Oil and Gas: In drilling rigs, refineries, and petrochemical plants.
  • Mining: In underground mines and processing facilities.
  • Chemical Industry: For mixing, conveying, and processing chemicals.
  • Pharmaceutical Industry: In areas with explosive dust or vapor atmospheres.
  • Food and Beverage: For areas with potentially combustible dust.

ABB’s range of hazardous motors is a testament to the critical importance of safety in industrial settings where explosive atmospheres and hazardous conditions are prevalent. Their unique design, adherence to stringent safety standards, and robust construction make them an indispensable choice in industries where standard electric motors would pose unacceptable risks. By using these specialised motors, companies can mitigate the dangers associated with potentially explosive atmospheres while maintaining reliable performance and compliance with safety regulations.
