YBX3 series high efficiency flameproof 3-phase asynchronous motor is a new product designed and developed by our company on the basis of YB3 and YB2 series.

Technical information:

     H80-355, Power:0.18-400kW, Protection Degree: IP55, Insulation Class: F, Cooling Method: Totally Enclosed Fan Cooled(Code IC411), Ambient Temperature of -15℃~+40℃, Altitude not exceeding 1000m above sea level

Main Feature and standards compliance: 

          According to GB3836.1-2010《Explosive atmospheres - Part 1: Equipment-General requirements》 and GB3836.2-2010《Explosive atmospheres – Part 2:Equipment protection by flameproof enclosures “d”》, the series motor is made into explosion-proof type. The efficiency is in accordance with the energy-saving evaluation value standard in GB18613-2012《Minimum allowable values of energy efficiency and energy efficiency grades for small and medium three-phase asynchronous motors》. The efficiency reaches the national level 2 energy efficiency, and has the characteristics of excellent performance, safe and reliable operation, lower vibration and noise than similar products, and meets the requirements of environmental protection.

The power grade and installation dimension of this series motor conform to the International Electrotechnical Commission (IEC) standard, and the corresponding relationship is the same as that of German DIN42673 standard, which is conducive to the matching of export and import equipment.
