3 PHASE EX-PROOF MOTORS
Gamak IE3 Ex-proof motors provide high safety in flammable and explosive environments with premium efficiency and low energy consumption.
- Lower energy consumption WITH up to 94.6% energy efficiency in the transition to efficiency class IE3.
- With the new efficiency classes, ease of use is provided with the possibility of B3 flanges up to 250 frames, B5 and B35 flanges up to 225 frames, B14 and B34 flanges up to 160 frames, B14/2 and B34/2 flanges up to 132 frames.
- Thanks to the possibility of use with drive; speed control, direction control, torque and current controls can be made.
- Designed for flammable and explosive gas and dust environments, Gamak Ex proof motors in IP65 protection class with class d protection structure meet ATEX or IECEx certification requirements according to 60079-0, 60079-1 and 60079-31 standards.
What is an Ex-Proof Motors?
If there is a need to use electric motors in flammable and explosive environments, Ex-proof motors should be preferred. Gamak flameproof ex-proof electric motors are electric motors that are resistant to gas or vapor explosions and designed to prevent sparks that may occur as a result of explosion from coming into contact with explosive gas or dust in the environment and causing explosion and ignition.
What are the Exproof Motor Features?
- Ex-Proof motors can be produced in F or H insulation classes upon request. While the copper and insulation varnish forming the stator with F class insulation withstand up to 155 degrees according to the relevant standards, this resistance limit is defined as 180 degrees in H class insulation. Insulation resistance is not related to the maximum surface temperature.
- The protection classes of Ex-proof motors are designed to be II 2G Exdb IIC T4 Gb for gas environment and II 2D Extb IIIC T135°C Db for dust environment.
- All GAMAK Ex-proof motors are manufactured with thermistor protection elements with a 130 degree trip limit. Thus, if the temperature of the winding heads in the motor reaches the relevant degree, the thermistor will prevent the motor from overheating by preventing electric current from flowing to the motor. Thermistor connections are the responsibility of the user.
- In order to limit the risks that may arise from static electrification in the products, the paint thickness on the protection housing is limited to 200 microns, and the raw material of the rotating plastic impeller is selected from special raw material with a surface resistance below E9 ohm.
Where are Ex-Proof EnginesUsed?
Ex-proof engines are used in many sectors where flammable and explosive materials are present. They are used in industrial sectors such as natural gas plants, paint, shipyards, chemical, pharmaceutical, perfume and in flammable and explosive gas and dust environments that pose a risk.
