Series YBXn flameproof motors

        Series YBXn flameproof motors are the basic series motors developed, designed and manufactured into total-enclosed self-fan-cooled squirrel-cage high-efficiency flame-proof three-phase induction motors by our company. The efficiency indexes of this series motors confirm to the energy-saving estimate value specified in GB18613-2002 Medium- and Small-sized Three-Phase Induction Motors Restriction Value of Energy Efficiency and Energy-Saving Estimate Value. This series motors have many remarkable features such as excellent performance, reliable operation, vibration and noise values lower than the like products etc. and confirm to environmental requirements.
        For this series motors, the output ratings and mounting dimensions conform to the specifications of IEC standards and the correlation between them basically agrees with EIN42673. The motors are easy to complete with export machinery and equipment and to supply as spare accessories in the import equipment.
        This series motors are designed and manufactured into flameproof type and the flameproof property conforms to China National Standards: GB3836.1-2000 Electrical Apparatus for Explosive Gas Atmospheres Part 1: General Requirements GB3836.2-2000 Electrical Apparatus for Explosive Gas Atmospheres Part 2: Flameproof Enclosuredand standards IEC79-1, BS4683 and EN50018. The explosion protection marks are Exd, ExdAT4 and ExdBT4. They are safe to use in the locations where there are explosive mixtures of gas- and vapor-air.
        ExdI motors are safe for use in the non-mining surfaces of underground coal mines where the explosive mixtures of methane or coal-dust are present.
        ExdIIAT4 and ExdIIBT4 motors are safe for use separately in plants where the explosive mixtures ofA and B Class, TI, T2, T3 or T4 are present.
        Based on series YBXn motors, the motors can also be manufactured for special environments, such as outdoor locations (YBXn-W type), indoor tropical humidity (YBXn-TH type), outdoor tropical humidity (YBXn-WTH type), indoor tropical arid (YBXn-TA type), outdoor tropical arid (YBXn-WTA type), indoor tropical (YBXn-T type), outdoor tropical (YBXn-WT type) and outdoor medium-chemical corrosion.
