YBK3系列煤礦井下用隔爆型三相異步電動機為軸向通風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系列而新設計的更新換代的煤礦井下用隔爆型電機基本系列，它具有效率高、轉矩大、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、壽命長等優點，隔爆結構合理、使用安全可靠，外形美觀等優點。產品技術水平達到國內先進水平。
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.
