YBS2 Series Explosion-Proof Motors for Conveyors

Description

YBS Series Flameproof Three-Phase Induction Motors for Conveyors The YBS series flameproof three-phase induction motors are specially designed for machinery used in coal mine excavation and tunneling operations. The motor frame is constructed from welded steel plates, with reinforced measures applied to the fan cover, terminal box, and insulation structure. Electrical performance, installation dimensions, rated power, and other specifications are identical to those of the YB2 series motors. The explosion-proof performance of this series complies with: GB 3836.1-2000 Electrical Apparatus for Explosive Gas Atmospheres – Part 1: General Requirements GB 3836.2-2000 Electrical Apparatus for Explosive Gas Atmospheres – Part 2: Flameproof Enclosure “d” The motors are designed as flameproof type with the marking Exd I, suitable for use in coal mine excavation and tunneling operations.
