Model Number: YB2 explosion-proof motor Brand Name: Yu Bao Key Specifications/Special Features: YB2 series three-phase asynchronous explosion-proof motor is introducedSeries YB2 flameproof three-phase asynchronous motor, is to meet factories, mines, explosive gas environment needs large power equipment ideal drive products, upgrading of YB series is my company's basic series of explosion-proof motor. With high efficiency and energy saving, low noise, long life, high reliability characteristics. Series YB2 flameproof three-phase asynchronous motor performance accord with GB3836.2-2010 "explosive gas environment with electrical equipment Part 2: flameproof "d", "regulations 7 the international electro technical commission standard IEC79-1 respectively made flameproof Exdl, ExdllAT4, neither ExdllBT4 is suitable for the coal mine digging face and factories have type IIA and IIB level temperature classes T1 - T4 groups exist for the dangerous sites with explosive air mixture. Application of the YB2 series three-phase asynchronous explosion-proof motorSeries YB2 flameproof three-phase asynchronous motor with ExdI explosion-proof logo motor, suitable for coal mine methane and coal dust explosion danger place; Motor with the ExdIIBT4 explosion-proof mark, applicable to factories with class II B, for temperature classes T1, T2, T3, and T4 group environment of the existence of explosive gas mixture; Motor with the ExdIICT4 explosion-proof mark, applicable to factories with grade II class C, temperature classes T1, T2, T3, and T4 group of explosive gas environment of the existence of the mixture. Series YB2 flameproof three-phase asynchronous motor basic upgrading of YB series of explosion-proof motor series, the series motor has small volume, light weight, beautiful appearance, safe and reliable operation, long service life, excellent performance, installation convenient use and maintenance. Series of the power rating of the motor and installation size in line with the international electro technical commission (IEC) standards, its corresponding relation with the German DIN42673 standard is the same, is advantageous to the export of equipment and the introduction of equipment of form a complete set of spare parts. This series motors explosion-proof performance meet GB3836.1-2000 "explosive gas environment with electrical equipment part 1: general requirements and GB3836.2-2000" explosive gas environment with electrical equipment part 2: flameproof "d" "regulation, also along with IEC79-1, BS4683 and the provisions of the EN50018 made flameproof. Explosion-proof marks for Exd Ⅰand Exd Ⅱ AT4 and Exd Ⅱ BT4, ExdIICT4, suitable for the sites with explosive air mixture. ExdI is suitable for the existence of the coal mine methane or coal dust explosive mixture of tunneling face environment.ExdIIAT4 applicable to factories with type IIA class, temperature classes T1, T2, T3, and T4 group explosive gas environment of the existence of the mixture. yb2explosion-proof motor model parameter list380V50Hz Motor model (kW) （A） （r/min） (η%) (cosφ) N.m Tst TN Ist
