YBK3 series flameproof 3-phase asynchronous motor for underground coal mine is a new product designed and developed on the basis of YBK2 series.

Technical information:

  H80-355, Power:0.75-355kW, 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 is made into explosion-proof type. The standard JB/T 9593.1-2015《Specification of flameproof three-phase asynchronous motors for mines. Part 1: YBK3 series flameproof three-phase asynchronous motors for coal mines (frame size 80～355)》 also comply with the provisions of MT451-1995《General specification for low voltage three phase flameproof induction motor for coal mine》. The products have excellent performance, safe and reliable operation, lower vibration and noise than similar products, and meet 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.
