YB3 explosion-proof motor description: YB3 series flameproof three-phase asynchronous motor is totally enclosed Nanyang Explosion Electric Co., Ltd. in a unified design industry developed on the basis of reference, fan-cooled, squirrel-cage, flameproof three-phase asynchronous motor Basic series. Efficiency of the implementation efficiency of the implementation GB18613-2006 "small and medium three-phase asynchronous motor energy efficiency of limited value and energy efficiency evaluation value" criteria in evaluating values ??of energy efficiency to achieve national two energy efficiency rating EFF1 European standards, and has excellent performance, safety and reliability , vibration, noise smaller than similar products, in line with environmental requirements. YB3 series flameproof three-phase asynchronous motors explosion-proof motor performance in line with GB3836.1-2010 "explosive atmospheres - Part 1: General requirements for equipment" and GB3836.2-2010 "explosive atmospheres - Part 2: the flameproof enclosure" d "protection provision of equipment ", the report co-IEC79-1, BS4683 and EN50018 provisions made flameproof. Proof mark for Ex d ⅠMb, Ex d ⅡAT4 Gb, Ex d ⅡB T4 Gb, applicable to the presence of explosive gas mixtures in place. YB3 explosion-proof motor environment: Ex d I Mb applicable to a gas atmospheres (except mining face). Ex d IIA T4 Gb applicable to factories with the IIA class, temperature class T1, T2, T3 and T4 group explosive gas mixtures in the environment. Ex d IIB T4 Gb suitable for factory use IIB class, temperature class explosive gas mixtures T1, T2, T3 and T4 groups present in the environment. YB3 based on the basic series motors can also be made YB3-W outdoor type, YB3-TH humid tropics type, YB3-THW outdoor humid tropics type, YB3-TA dry tropical type, YB3-TAW outdoor dry tropical type, YB3-WF1 suitable for different environmental conditions of the motor outdoor medium corrosion type. YB3 explosion-proof motor Technical parameters: Rated voltage: 380V, 660,1140,380 / 660,660 / 1140V rated frequency: 50Hz power range: 0.12-315KW Insulation class: F, H protection: IP55
