YB3 motor is a basic series of high-efficiency explosion-proof motors designed and developed by our company using advanced domestic and foreign technologies, combined with the actual situation of China's explosion-proof motor industry and market. It is an updated product of the YB2 series. The efficiency index complies with the provisions of "Motor Energy Efficiency Evaluation Level 2" in GB18613-2012 "Energy Efficiency Limit Values and Energy Efficiency Grades for Small and Medium sized Three Phase Asynchronous Motors". This series of motors complies with the national standards GB3836.1-2010 "Explosive Atmospheres Part 1: General Requirements for Equipment" and GB3836.2-2010 "Explosive Atmospheres Part 2: Equipment Protected by Explosion proof Enclosures". At the same time, the design of its explosion-proof structure and parameters refers to the standards of IEC60079-1 "Structure and Testing of Explosion proof Enclosures for Electrical Equipment" and EN50018 "Electrical Equipment for Explosive Environments". The electric motor is made of explosion-proof type. The explosion-proof standard is Ex d I Mb Ex d II AT4 Gb,Ex d II B T4 Gb,Ex d II C T4 Gb, Suitable for fixed equipment underground in coal mines and places with explosive gas mixtures of Class IIA, IIB, and IIC used in factories, with temperature groups ranging from T1 to T4. The power level and installation dimensions of this series of motors comply with the International Electrotechnical Commission (IEC) standards. And the corresponding relationship is the same as the YB2 series, so it can be interchanged with the YB2 motor. Product Parameters
