YBBP series of explosion-prooffrequency control three-phaseasynchronous motor is our company on the basis of YB3 series motorscombined with the current state, internal and external electromagneticstructllre, technology, materials and other aspects of the new technologyand new product development. lt is characterized by the use of motoland frequency converter, can achieve a wide range of smooth steplessspeed regulation, in which the frequency range of 5~50Hz for constanttorque converter,50~100Hz for constant power frequency conversion.motor with axial flow fan, ensure that the cooling effect at differentspeeds,toensure motor safety, normal operation.

This series motor power rating,installation size to meet thestandard of the lnternational Electrotechnical Commission (IEC) andthe corresponding relationship with Germany DIN4267 standard is thesame, is conducive to supporting the export of equipment and theintroduction of equipment spare parts.

This series of motors is in accordance with the GB3836.1-2010“explosive environment first parts:General requirements for equipment'and BG3836.2-2010“explosive environment: the provisions of the”d“protection equipment, also in line with the requirements of Bs4683EN50018 andIEC79-1.ExdIMb，ExdIlAT4Gb，Exd II BT4Gb ExdIICT4 Gb ，are used in explosive environment.

Exd I Mb installed in the coal mine methane explosive environmentequipment, with the“high”protection level, the level of security, sothat the normal operation of the equipment or in the suddenemergence of gas and equipment failure conditions are not possibleto become a light source, suitable for non working surface withelectrical equipment .

Exd II AT4Gb、Exd II BT4Gb is suitable for the equipment ofexplosive gas env ironmen, such as coal mine, chemical, chemical,etcExdlICT4 Gb Apply to factory there are hydrogen and acetylenein the dangerous sites with explosive air mixture.

This series of explosion-proof frequency control three-phadeasynchronous motor and frequency conversion device constitute 

thespeed control system and other speed control mode compared withenergysaving effect is remarkable,the speed performance is good, thespeed range is wide, with low noise, vibration, can be used with allkinds of domestic and foreign inverter, help to achieve automatic control.
