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 IEC60079, but is higher than the IEC60079 standard. According to my country's specific conditions, several key points of my country's original standards were added to IEC60079 to form the GB 3836 explosion-proof standard. new features.
Efficient
It reaches the second level value of the European CEMEP-EU efficiency grade motor standard and complies with 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
The voltage range is 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 motor is permanently lubricated, and the 160-355 is equipped with a refueling device.
