Product Overview
The YBX3 series of high-efficiency, high-voltage, explosion-proof three-phase asynchronous motors (H355-560) are new products developed by our company, incorporating the advantages of similar motors from both domestic and international sources and utilizing new materials and processes. They comply with GB38361-2010 "Explosive atmospheres Part 1: Equipment general requirements" and GB3836.2-2010 "Explosive atmospheres Part 2: Equipment protected by 'd' type flameproof enclosures", GB3836.3-2010 "Explosive atmospheres Part 3: Equipment protected by 'e' type increased safety enclosures"; the explosion-proof structure parameters of the flameproof motor refer to IEC60079-1 "Electrical apparatus-Flameproof enclosures-Construction and testing" and EN50018 "Electrical apparatus for explosive gas atmospheres "d" type"; the explosion-proof mark is ExdblMb、ExdbTAT4 Gb、ExdbTBT4 Gb. The motor efficiency meets the Class 1 energy efficiency requirements of GB30254-2013.
Product Applications
Dust explosion-proof motors are mainly used in places where combustible dust exists, such as pharmaceuticals, textiles (such as cotton, flax, and chemical fibers), metallurgy (magnesium powder, aluminum powder, carbon powder), grain processing (such as wheat, corn, and grains), feed processing (blood meal, fish meal), fertilizers, tobacco, papermaking, synthetic materials (such as plastics and dyes), and building materials.
Product Features
This series of motors features an aesthetically pleasing design, high performance indicators, reliable operation, small size, low vibration, low noise, and high efficiency and energy saving. Derived from the VBX3 series are outdoor (W), tropical (H), outdoor tropical (WTH), and corrosion-resistant (WF1, WF2) types. Marine series explosion-proof three-phase asynchronous motors can also be derived based on national standard GB/T7060 "Technical requirements for marine rotating electrical machines"; their performance indicators, installation, and dimensions are the same as the basic series.
