YB3系列隔爆型三相異步電動機（以下簡稱YB3電機）是我公司采用國內外先進技術，結合我國防爆電機行業和市場的實際情況設計開發的高效防爆電機基本系列，是YB2系列的更新換代產品。效率指標符合GB18613-2012《中小型三相異步電動機能效限定值及能效等級》中的“電動機節能評價值2級”的規定。

YB3 series? flameproof three-phase asynchronous motor (hereunder referred to as the YB3 motor) is our company uses advanced technology from domestic and overseas , combining the actual situation of Chinese? Explosion proof electric motor’s industry and market ,we design and development of efficient basic series, YB3 series is the upgrade of YB2 series motors.? The Efficiency indicators meet he "motor energy conservation value level 2".
?in? GB18613-2012《small and medium sized three-phase asynchronous motor limited value of energy efficiency and energy efficiency grade》
本系列電動機符合國家標準GB3836.1-2010《性環境 第1部分：設備 通用要求》和GB3836.2-2010《行環境第2部分：由隔爆外殼“d”保護的設備》的規定。同時其隔爆結構和參數的設計參照了IEC60079-1《電氣設備隔爆外殼的結構和試驗》和EN50018《性環境用電氣設備“d”》標準。電動機制成隔爆型。防爆標準為Ex d I Mb、Ex d II AT4 Gb、Ex d II B T4 Gb、Ex d II C T4 Gb，分別適用于煤礦井下固定式設備及工廠用II A級、IIB、IIC級，溫度組別為T1~T4組性氣體混合物的場所。

This series motor conbs to the national standard GB3836.1 - 2010 《explosive environment Part 1: general requirements for equipment 》and GB3836.2-2010 《explosive environment part 2: the flame-proof shell" d "protection equipment》,At the same time, the flame-proof structure and beters design with reference to the IEC60079-1 《the explosion-proof electrical equipment enclosure structure and test》and EN50018 《explosive environment with" d "electrical equipment》 standard. The motor is EX type. Explosion-proof standards are Ex d I Mb, Ex d II AT4 T4 Gb Gb, Ex d II B, Ex 2 d C T4 Gb, respectively applicable to fixed equipment in coal mine and factory level with A grade II, IIB, IIC, temperature classes for T1 ~ T4 group of sites with explosive air mixture.
本系列電動機功率等級和安裝尺寸符合國際電工委員會（IEC）標準。且對應關系和YB2系列相同，因此可以與YB2電機互換。
