M2JA series (80~355) flameproof motors are the latest flameproof motor manufacturing technology of ABB introduced by Shanghai ABB Motor Co., Ltd. in the 21st century. They are currently the most advanced Class 4 flameproof motors for factories in China (Ex d II C). Products (temperature group T1~T5).
In hazardous areas, the correct use of explosion-proof electrical devices is extremely important. For this reason, many countries have regulations on the structure and usage of explosion-proof electrical devices. GB 3836~2000 The standard for electrical equipment for explosive gas environments is equivalent to the standard C60079, but is higher than the standard C60079. According to the specific conditions of our country, several key points of our original standard are added to IEC60079 to form GB 3836 New features of explosion-proof standards.
The M2JA series flameproof three-phase asynchronous motors for hazardous environments adopt "Ex d" type explosion protection and are suitable for use in hazardous places such as petrochemical plants. The maximum surface temperature group is T1~T5. Its shell can withstand explosions caused by flammable mixtures that penetrate into the motor through any contact surface or structural gap of the shell without being damaged. The explosion-proof performance is certified by LCIE (BV).
Efficient
It reaches the second level value of the European CEMEP.EU efficiency grade motor standard and meets the energy efficiency limit value of the People's Republic of China national standard GB18613-2002 for small and medium-sized three-phase asynchronous motors.
Dual bandwidth voltage
Voltage range 220V~690V, suitable for 50Hz and 60Hz power supplies
low noise
By optimizing electromagnetic design, ventilation conditions, structural dimensions and other technologies, the M2JA series motors have lower noise.
High bearing load capacity
The motor uses deep groove ball bearings with long service life. The 80-132 center height motors are permanently lubricated. The 160-355 motors are equipped with a refueling device.
Good reliability
The motor has a fully enclosed air-cooled structure, with a protection level of P55. The materials and processes meet environmental requirements. The motor has high mechanical strength, is sturdy and durable, has strong anti-rust and anti-corrosion properties,
