Introduction:

YB3 series explosion proof three-phase induction electric motor is applicable to be used a place containing explosive mixtures of iammable gas or vapour and air. YB3 ranges of three-phase induction motors are flameproof motors obtained by renewal and generation-changing of YB2, YB ranges of motors. The performances of the products have come up to advanced international standards. Provide petrol and chemical industry with new generation driving equipment which is safer, more advanced, more reliable and more efficient. The outputs, mounting dimensions and their corresponding relationships comply with IEC standards.
YB3 series of motors meet GB755-2008 “Rotating electrical machines-Rating and performance”, company standards of Q/320206JLAB01-2009 “ Technical specification of YB3 series of flameproof three-phase induction motor (Frame Number: H63~355)”. Their flameproof performance should meet GB3836.1-2010《Explosive atmospheresPart1: Apparatus General requirements》 and GB3836.2-2010《Explosive atmospheres, Part2: Apparatus protected by the crust for flameproof “d” 》. The flameproof types of this series motors are ExdI, ExdIIAT4 and ExdIIBT4，and suitable for the non-mining working area in underground mine or the dangerous locations in factories where there are the explosive gas of class IIA and IIB and temperature of class T1～T4. YB3 series motors have the following types: humid tropics type (YB3-TH), dry tropics type (YB3-TA), outdoor type (YB3-W), outdoor medium-anticorrosion type (YB3-WF1) and outdoor humid type (YB3-THW),outdoor dry tropics type (YB3-TAW), indoor tropics type (YB3-T), outdoor tropics type (YB3-TW).
Our YB3 series explosion poof three phase induction electric motor have obtained industrial Production License, Explosion-proof Certificate etc.
