Scope

Scope: This standard specifies the types, basic parameters and dimensions, technical requirements, test methods, inspection rules, and marking, packaging, and transportation requirements for the YFBX4 series high-efficiency dust-proof explosion-proof three-phase asynchronous motors (with base numbers 80~355). This standard applies to the YFBX4 series high-efficiency dust-proof explosion-proof three-phase asynchronous motors (with base numbers 80~355) (hereinafter referred to as "motors"). All other series of motors derived from this series can also refer to this standard for implementation. Main technical content: — The YFBX4 series high-efficiency dust-proof explosion-proof three-phase asynchronous motors (with base numbers 80~355) do not have national or industry standards, and this series fills a gap in the domestic motor industry, achieving high efficiency for small-center-high dust-proof explosion-proof motors; — The explosion-proof structure complies with GB 12476.5-2013 "Electrical Equipment for Flammable Dust Environments - Part 5: Shell Protection Type 'tD'". This series of products can be used in flammable dust environments; — The efficiency indicators meet the requirements of GB 18613-2012 Class 1 and GB/T 32891.1-2016/IEC 60034-30-1:2014 "Rotating Electric Machines - Efficiency Classification (IE Code) - Part 1: AC Motors Powered by Grid". The maximum protection level can reach IP65, which is higher than the IP5X specified in GB 12476.5-2013; — When operating at the reference voltage, reference frequency, and rated output power, the efficiency of the YFBX4 series high-efficiency dust-proof explosion-proof three-phase asynchronous motors meets the corresponding Class 1 energy efficiency limits in GB 18613-2012 for medium- and small-sized three-phase asynchronous motors, and also meets the IE4 energy efficiency values in GB/T 32891.1-2016 (IEC 60034-30-1:2014). When the efficiencies of the two are different, the highest value is selected as the
