M2JAX 80M4A 4 3GJA082301-BSD 0.55kW B5 IE3 Flameproof Three-phase Induction ABB Motor

In the dangerous area, the proper use of explosion-proof electrical apparatus is very important. Therefore, many countries are on the explosion-proof electrical device structure and usage regulations. GB 3836~2000 explosive gas atmospheres standard equivalent electrical equipment with IEC60079, but higher than that of the IEC60079 standard, according to the specific situation of our country, on the basis of IEC60079 and the standard of our country several key points, the formation of a new feature of GB 3836 explosion-proof standard.

M2JAX series (80~355) flameproof motor is manufacturing technology Shanghai ABB Motor Co., ABB company to introduce the latest twenty-first Century flameproof motor, combined with the characteristics of Chinese GB 3836-2000 standard and development, currently the most advanced factories with 4 flameproof motor (Ex D LLC) products (T1~T4 temperature group).

Technical characteristics: High efficiency. To the European standard two motor efficiency rating value, meet the national standard limit value of People's Republic of China small and medium-sized three-phase asynchronous motor energy efficiency. Dual band wide voltage. The voltage range of 220V~690V, 50Hz and 60Hz power supply. Low noise. Through the optimization of electromagnetic design, ventilation, structure technology, M2JA series motor with low noise. The bearing load capacity is high. Motor selection of deep groove ball bearings, long service life, high motor 80-132 Center for permanent lubrication, 160-355 is provided with a refueling device. Very good reliability The motor is fully enclosed air cooling structure, protection grade IP55, materials and processes to meet environmental requirements. The motor has high mechanical strength, durability, rust and corrosion resistance strong. Winding reliability, a class F insulation structure, B class. According to user needs and increase the PTC thermistor or thermal switch.

In industries sector such as petroleum, natural gas and chemical,all kinds of inflammable gas or steam may be released in the production process. For instance, refineries have propane, butane,and gasoline, ethylene, and acetylene, etc. Fertilizer plants have ammonia, methanol, carbon oxide, water gas, air, etc. Mixed with air, these substances form a mixture with the risk of explosion.A serious explosive may occur if the mixture is in an explosive ambience, co-existing with tinder.

Normally, squirrel-cage motors do not produce sparks.During operation, sparks may appear due to damaged and aging of winding insulation or electric arcs because of loose connection between electric parts. Mechanical failure or other reasons that may give rise to an overload of the motor and bring high temperature and result in an ignition.

Therefore, effective measures should be taken for all types of flameproof motors against sparks, electric arcs and dangerous temperatures.

"Ex d" flameproof motor is a type of electrical apparatus operating in explosive zones.Its enclosure will be able to suffer from an explosion of inflammable gas or steam, which penetrates into the internal part of it through any joints of structural openings.Furthermore, this explosion will not cause ignition in the external explosive gas atmosphere formed by one or more types of gas or steam.

Working conditions The ambient air temperature changed with the season but not more than -15 DEG ~40 DEG Altitude: not more than 1000M Frequency: 50Hz/60Hz Voltage: 220V~690V Working mode: continuous (S1) Start mode: full voltage starting, Y- delta starting or reactance starting Transmission mode: use the elastic coupling or spur gear drive: F insulation, heating. But the stator winding temperature rise limit of 80K, according to the B class (resistance). Bearing allowable temperature does not exceed 95 degrees (thermometer). Cooling method: IC411

Voltage and performance parameters: Wide voltage design adopts M2JA series motor, motor efficiency, in various voltage condition of the power factor and speed change slightly. 50Hz:220 - 240V / 380-420V; 380 - 420V / 660-690V / y, Delta connection. 60Hz:460V: = 3kW, Y; 3kW, Delta connection. If the user needs a specific working voltage, can be supplied according to special requirements.

M2JAX series flameproof three-phase induction motors for Explosive atmospheres with "Ex d" type of protection, are designed for "Ex d ll C T4 Gb" grade as standard. Motors are extensively applied in chemical, oil and gas industries. The motor enclosure will be able to withstand an explosion of inflammable gas or vapour, which penetrates into the internal part through joints of structural openings. Furthermore, no internal explosion can be transmitted to the explosive atmosphere surrounding the motor.

M2JAX series flameproof motors meet the standard of IEC60079- 0:2007/IEC60079-1:2007 and GB3836.1-2010/GB3836.2-2010. It is certified by CQST and the efficiency rating reaches IEC IE2, which is in accordance with China Grade 3 efficiency standard.
