YBS Conveyor Flame Retardant AC Motor

Description&Application

YBS series flameproof three-phase asynchronous motors for conveyors (hereinafter referred to as motors) are special motors for driving flexible scraper conveyors, belt conveyors, pump station equipment or other equipment in underground coal mines. They include single-speed and multi-speed explosion-proof motors. They are widely used in coal mines and have the advantages of high efficiency, high stall torque, high reliability, low stall current, strong overload capacity, etc. The motors are beautiful in appearance and easy to use and maintain.
This series of wolong motors is suitable for the coal industry and places where explosive gas mixtures of methane or coal dust exist. They drive various machines such as flexible scraper conveyors, belt conveyors, crushers, pump stations or other machines in underground coal mines.
YBS series motor can be customized according to customer requirements to Nanyang brand, Wolong brand, Schorch brand, etc.
