YBK3 Flameproof motor for underground coal mines
Product Detail
YBK3 series high efficiency flameproof three-phase asynchronous motor is our upgraded explosion-proof mine industry motor, the series motor has the advantages of small volume,light weight,beautiful appearance,reliable operation,long service life,excellent performance as well as convenient installation,operation and maintenance.
The series motor's power level,installation dimensions comply with IEC standard,with coincident corresponding relation ship with German standard DIN42673. It is conducive for the export equipment matching and introduction of spare parts for equipment.
For Ex d I Md equipment that is installed at coal mine methane explosive environment, has"high" protection level.This level has sufficient safe performance,it cause impossibility to be the ignition source during equipment normal running,or under expected failure conditions for the period between gas suddenly appeared and equipment power off,it is applicable for electrical equipment for non excavation working face.Ex d ⅡA T4 G b, Ex d ⅡB T4 Gb are applicable for equipment with explosive gas environment except coal mine,with"high"protection level,it is not a source of ignition during normal running or under expected fault conditions.
