YBSD series flameproof three-phase asynchronous motor for convey

Application

YBSD series conveyors explosion proof three-phase asynchronous motors are special motors for driving bendable scraper conveyors, belt conveyors or other equipment in coal mines. The explosion-proof performance of the motor is in accordance with GB3836.1-2010 “Explosive Atmosphere Part 1: General Requirements for Equipment” and GB3836.2-2010 Explosive Atmosphere Part 2: Equipment Protected by Flameproof Enclosure “d”. Its explosion-proof mark is “Ex d I Mb” (“Exd I”-before 2010). It is suitable for the place where the explosive gas mixture of methane or coal dust exists.
