The YBX3 series high efficiency flameproof three-phase asynchronous motor is a series of self sealing fans, fan fans, squirrel cage and high efficiency flameproof three phase induction motors developed by our company. The efficiency conforms to the 2 level energy efficiency of GB18613-2012 "small and medium three phase asynchronous motor energy efficiency limits and energy efficiency grades", and has the characteristics of excellent performance, safe and reliable use, vibration and noise reduction compared with the similar products, which is in line with environmental protection requirements. The explosion-proof performance of this series of motors is consistent with GB3836.1-2010's explosive environment first parts: General requirements for equipment and GB3836.2-2010, the second part of explosive environment: the flameproof type is made by the provisions of the device protected by flameproof enclosure "d". The explosion-proof marks are Ex D II A T4 Gb, Ex D II B T4 Gb, Ex D II.
