Yb3 Series High Efficiency Explosion Proof Three Phase Low Voltage Asynchronous Motors

YB3 sequence higher performance explosion evidence three period reduced voltage  asynchronous motors(H80~355mm)(hereunder referred to as the YB3 motor) is our organization employs innovative engineering from domestic and abroad, combing the true predicament of Chinese Explosion evidence electric motor’s sector and marketplace.  We design and develop of successful standard collection, YB3 collection is the improve of YB2 collection motors, which in line with the 3rd effectiveness regular degree IE3. 

The motor is EX sort. Explosion-evidence expectations are EXDIMb, EXDIIAT4 Gb, EXDIIB, EXDIICT4 Gb, respectively relevant to set equipmemt in coal mine and manufacturing unit level with A greade II, IIB, IIC, temperature courses for T1~T4 group of sites with explosive air mixture.
