Detailed Product Description

YB2 series motors are of remarkable features, such as compact construction, lightweight, attractive appearance, safe and reliable operation, long operation life, excellent performance and easy maintenance.

For this series motors, the output ratings and mounting dimensions conforms 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 General Requirements.

GB3836.2-2000 Electrical Apparatus for Explosive Gas Atmospheres Flameproof Enclosure "d", standards IEC79-1, BS4683 and EN50018.

The explosion protection marks are ExdI, ExdIIAT4, and ExdIIBT4. They are safe to use in the locations where there are explosive mixtures of gas-and vapor-air. "ExdI": Safe for use in the non-mining surfaces of underground coal mines where the explosive mixtures of methane or coal-dust are present. "ExdIIAT4": Safe for use in plants where the explosive mixtures of II A Class, T1, T2, T3, or T4 are present. "ExdIIBT4": Safe for use in plants where the explosive mixtures of II B Class, T1, T2, T3, or T4 are present.

Based on series YB2 motors, the motors can also be manufactured for special environments, such as outdoor locations(YB2-W type), indoor tropical humidity(YB2-TH type), outdoor tropical humidity(YB2-WTH type), indoor tropical arid(YB2-TA type), outdoor tropical arid(YB2-TA type), outdoor tropical arid(YB2-WTA type), indoor tropical(YB2-T type), outdoor tropical(YB2-WT type) and outdoor medium-chemical corrosion locations(YB2-WF1 type).
