YB2 series explosion-proof three-phase asynchronous motor is a new kind of product developed on the basis of YB and YB2 series motors adopts the latest technology in the world such as electromagnetic structure, craft and materials etc.
It has the advantages of high efficiency, energy saving, large temperature rise margin, long life, good performance, low noise, advanced flameproof structure, high reliability, convenient use and maintenance .
YB2 explosion-proof motor is used as fixed equipment for underground coal mine (non-mining work). It also used as drive device that applied to the place which composed of explosive mixture(combined air with factory lIB, T1-T4 temperature group flammable gas/steam.
It is mainly used in coal mine, petroleum natural, petrochemical and chemical industries. In addition, it has been widely used in textile, metallurgy, city gas, transportation, grain and oil processing, paper making, medicine and other departments. As the main power equipment, explosion-proof motor is usually used to drive pumps, fans, compressors, conveyors and other transmission machinery.
