YBK3系列煤礦井下用隔爆型三相異步電動機為軸向通風(fēng)全封閉自扇冷鼠籠型隔爆型三相異步電動機，是我國取代YBK系列而新設(shè)計的更新?lián)Q代的煤礦井下用隔爆型電機基本系列，它具有效率高、轉(zhuǎn)矩大、過載能力強，噪聲低、振動小、溫升裕度大、性能良好、安裝維修方便、壽命長等優(yōu)點，隔爆結(jié)構(gòu)合理、使用安全可靠，外形美觀等優(yōu)點。產(chǎn)品技術(shù)水平達(dá)到國內(nèi)先進(jìn)水平。

YBK3 series flameproof three-phase asynchronous motors used in underground coal mines are axial-ventilation, fully enclosed, fan-ventilated, and squirrel-cage motors, which are newly designed by our company to supersede the series of YBK and constitute the basic series of flameproof motors used in underground coal mines. This series motors are of remarkable features, such as high efficiency, large torque, large overload capacity, low noise and vibration, large margin of temperature rise, excellent performance, easy installation and maintenance, long lifespan, reasonable flameproof structure, safe and reliable operation, and beautiful appearance. The technical level reaches the advanced level at home.
