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.
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.
