请注意:此版本的所有临时修订版将在您购买时提供。UL 1004-9与《旋转电机标准-一般要求》UL 1004-1一起阅读。对于UL 1004-9涵盖的机器，仅UL 1004-1的以下部分适用:部件；机械装配；框架和外壳；接地；接地标识；防腐；工厂接线端子和引线；间距（额定电压为1000 V或以下时）；和载流部件。对于这些章节，除非本标准进行了修改，否则UL 1004-1的要求适用。在本标准中，术语“机器”代表并等同于术语旋转电机和旋转机器，并被理解为指本标准范围内的所有类型的电动机和发电机。术语“机器”被理解为同时适用于交流和直流机器。 这些要求适用于带成型绕组的现场安装电机，额定电压为460 V至34000 V。本标准也适用于采用随机绕组的现场安装电机，额定电压为1000 V至7200 V。拟用于国家电气规范NFPA 70中规定的危险场所的电机，可能需要满足国家电气规范NFPA 70中规定的其他要求。这些要求不包括密封（密封型）电机压缩机零件，这些零件根据密封制冷剂电机压缩机标准UL 984进行评估。这些要求不包括IEEE C50规定的额定功率为10 MVA及以上的特殊发电机（如氢冷（涡轮）发电机）。12，IEEE标准，适用于额定功率为5 MVA及以上的水轮机用凸极50 Hz和60 Hz同步发电机及发电机/电机； IEEE C50。13，IEEE标准，适用于额定功率为10 MVA及以上的50 Hz和60 Hz圆柱转子同步发电机；或IEC 60034-3，旋转电机-第3部分:蒸汽轮机或燃气轮机驱动的同步发电机的特殊要求。

Please note: All interim revisions for this edition available at time of your purchase will be included.UL 1004-9 is intended to be read together with the Standard for Rotating Electrical Machines - General Requirements, UL 1004-1. For machines covered by UL 1004-9, only the following Sections of UL 1004-1 are applicable: Components; Mechanical Assembly; Frame and Enclosure; Grounding; Grounding Identification; Protection Against Corrosion; Factory Wiring Terminals and Leads; Spacings (when rated 1,000 V or less); and Current-Carrying Parts. For these Sections, the requirements of UL 1004-1 apply unless modified by this Standard.For the purposes of this Standard, the term "machine" is representative of and equivalent to the terms rotating electrical machine and rotating machine, and is understood to mean all manner of electric motors and generators covered by the scope of this Standard. The term "machine" is understood to apply to both AC and DC machines.These requirements apply to field-installed machines with form wound windings and rated for applications between 460 V and up to 34,000 V.This standard also applies to field-installed machines employing random wound windings and rated for applications above 1,000 V and up to 7,200 V.Machines intended for use in hazardous locations as defined in the National Electrical Code, NFPA 70, may have additional requirements to be met as specified in the National Electrical Code, NFPA 70.These requirements do not cover sealed (hermetic type) motor-compressor parts, which are evaluated under the Standard for Hermetic Refrigerant Motor-Compressors, UL 984.These requirements do not cover special generators (such as hydrogen cooled (turbo) generators) rated 10 MVA and above which are covered under IEEE C50.12, IEEE Standard for Salient-Pole 50 Hz and 60 Hz Synchronous Generators and Generator/Motors for Hydraulic Turbine Applications Rated 5 MVA and Above; IEEE C50.13, IEEE Standard for Cylindrical-Rotor 50 Hz and 60 Hz Synchronous Generators Rated 10 MVA and Above; or IEC 60034-3, Rotating electrical machines - Part 3: Specific requirements for synchronous generators driven by steam turbines or combustion gas turbines.
