WEG Explosion-Proof Electric Motor 4 kW 1450 rpm: Reliable Power Solution for Explosive Atmospheres
Where Reliability and Power Come Together: WEG Electric Motor Exproof 4KW 1450 rpm B3 Flange W21 112M-04
Special safety precautions are crucial for electrical equipment used in industrial facilities in areas where explosive atmospheres (flammable gases, vapors, mists, or combustible dusts) are present. WEG Explosion-Proof electric motors are designed to eliminate the risk of explosion due to sparks or overheating in such hazardous areas.
A WEG Explosion-Proof motor with 4 kW (5.5 hp) and 1450 rpm (4 poles) is the ideal solution for applications requiring particularly high safety standards and efficiency. WEG, headquartered in Brazil, is a globally recognized leader in electric motors and automation solutions.
Operating Principle: WEG Explosion-Proof motors generally operate on the principle of a three-phase asynchronous motor. The key difference is that the motor's housing and connecting elements are heavy-duty and sealed to prevent any internal explosion from leaking out. Furthermore, the surface temperature generated by the motor during operation and the insulation system are determined in accordance with the ignition class (Class T) of the gas or dust in the explosive atmosphere.
These motors are certified in accordance with the EN 60079 series standards and the ATEX (European Union Explosive Atmospheres Directive 2014/34/EU) directive. The "Ex" marking indicates the type of protection, gas/dust group, device category, and temperature class (e.g., II 2G Ex d IIB T4 or Ex de IIC T4).
What is a WEG Explosion-Proof Electric Motor and How Does It Work?
Explosion-Proof motors are specially designed to contain any explosion or spark that may occur within their enclosure and prevent it from spreading to the outside explosive atmosphere. Furthermore, their surface temperatures are controlled to remain below the ignition temperature of flammable materials in the environment.
WEG Explosion-Proof Electric Motor 4 kW 1450 rpm Features and Advantages:
Power (4 kW / 5.5 HP): Provides sufficient mechanical power for many medium-power equipment such as industrial pumps, fans, mixers, and conveyors.
Rotational Speed (1450 rpm - 4 Poles): This is one of the most commonly used speeds and is suitable for many pump and general industrial machinery applications.
Explosion-Proof Design: Provides safe and trouble-free operation in gas, vapor or dust environments that pose a risk of explosion (such as Zone 1, Zone 21). Prevents spark formation and overheating.
High Energy Efficiency: They typically have an efficiency class of IE2 (High Efficiency) or IE3 (Premium Efficiency) . This means low operating costs and energy savings.
Durability and Robustness: Designed with aluminum or cast body (e.g. for 112M frame size), they offer high resistance to harsh industrial conditions, mechanical shocks and vibrations.
Protection Class (IP55/IP65): Provides high protection against dust and water. Higher protection classes (IP56, IP66) may also be available.
Thermal Protection: Equipped with thermal protection systems such as internal PTC thermistors (trip at 150°C) or RTD-Pt100 sensors to prevent the motor from overheating.
Inverter Compatible: Designed for use with frequency converters (speed controllers), providing more precise speed control and additional energy savings.
Various Mounting Types: Offers different mounting types such as foot (B3), flange (B5, B14) or combinations of these (B35).
Areas of Use:
WEG Explosion-Proof electric motors are used in all hazardous areas where flammable and explosive materials are present:
Oil and Gas Industry: Refineries, natural gas plants, fuel stations, pipelines, wellhead equipment.
Chemical and Petrochemical Industry: Production, storage and transfer of solvents, acids, alcohols, dyes and other flammable/explosive chemicals.
Mining: Coal mines and other explosive dust environments.
Food and Beverage Industry: Areas where flammable substances such as alcohol and sugar powder are present (e.g. flour mills, sugar factories, alcoholic beverage production facilities).
Pharmaceutical and Cosmetics Industry: Production areas where flammable vapors or dusts are present.
Paint and Varnish Facilities: Painting booths, solvent storage areas.
Woodworking Industry: Areas where wood dust poses an explosion risk.
Wastewater Treatment Plants: Areas where methane gas formation occurs.
