YBK2 series three-phase explosion-proof low voltage induction motor (frame 100-315) is the same as YB2 series motor at technical data; the difference is that YBK2 series uses armor plate jointing frame. So it is good at Strength and hardness and mainly used for  coal mining .

   YBK2 series three-phase explosion-proof induction motor are made according to GB3836.1-2000 <Electrical apparatus for explosive gas atmospheres-Part 1: General requirements>and GB3836.1-2000 < Electrical apparatus for explosive gas atmospheres-Part 2: Flameproof enclosure “d”>. The motor Power rating and dimension are built to comply with International Electro technical Commission (IEC) standards, which is helpful for the export and import equipments.
