旋转电机 第30-1部分：线操作交流电机的效率等级（IE代码）

[中文适用范围]： IEC 60034-30-1:2025规定了适用于根据IEC 60034-1或IEC 60079-0标准进行额定，并且适用于50 Hz或60 Hz（或两者）正弦波电压供应的单速电动机的效率等级。本文件中涵盖的电动机具有以下特性： - 额定功率 PN 范围为 0.12 kW 至 1 000 kW； - 额定电压 UN 范围为 50 V 至 1 000 V（含）； - 极数为 2、4、6 或 8； - 在额定功率下可连续运行，且温升在规定的绝缘温度等级内； 注 1：本文件涵盖的电动机大多数适用于 S1（连续运行）工况。然而，有些适用于其他工况的电动机仍可在额定功率下连续运行，这些电动机也包含在本文件中。 - 标明的环境温度范围为–30 °C 至 +60 °C； 注 2：额定效率和效率等级基于 IEC 60034-2-1 的 25 °C 环境温度。 注 3：专门适用于–30 °C 以下或+60 °C 以上的温度的电动机被视为特殊结构，因此本文件不涵盖这些电动机。 注 4：适用于最高至400 °C温度等级的排烟电机包含在本文件中。 - 标明海拔高度不超过4 000 m； 注 5：额定效率和效率等级基于海拔不超过1 000 m的额定值。 本文件建立了一组基于供电频率、极数和电机输出功率的标称效率值。本文件不区分电机技术、供电电压或专门用于变频器运行的绝缘加强电机，尽管并非所有电机技术都能达到更高的效率等级（见表1）。这样可使不同电机技术在能耗效率方面进行完全比较。 本文件不涵盖电力驱动系统的效率。由于供电电压谐波含量、电缆、滤波器和变频器中的损耗不在此范围内。 本文件涵盖法兰、底脚或轴的机械尺寸不同于IEC 60072-1的电机。包括带有非标准轴和法兰的齿轮电机。 本文件不适用于以下情况： - 10极或以上单速电机或多速电机； - 带有机械换向器的电机（如直流电机）； - 完全集成到机器中（如泵、风扇和压缩机）的电机，即使提供临时端盖和驱动端轴承，也难以单独进行测试。这意味着该电机： a) 与驱动单元（如轴或外壳）有共用部件（除螺栓等连接器外）； b) 没有设计成可以完全分离并作为独立电机运行的形式。 换句话说，如果分离过程使电机无法工作，则电机将被排除在本文件之外； - 全封闭风冷式机器（TEAO，IC418），即设计用于通过外部通风设备进行外部冷却的全封闭框架表面冷却机器。此类电机的效率测试可在移除风扇并使用外部风扇以与原风扇相似的风量进行冷却的条件下进行； - 整合了变频器的电机（紧凑型驱动器），当电机无法与变频器分离测试时。紧凑型驱动器的能量效率分类基于完整产品（PDS，即电力驱动系统），其定义见IEC 61800-9-2； 注 6：当电机和变频器可以分离，并且电机可以独立于变频器进行测试时，电机不被排除在本文件之外； - 当制动器是电机内部结构的组成部分，并且在测试电机效率时无法移除或由其他电源供电的制动电机； 注 7：只要可以不考虑制动器损耗（例如通过拆除制动器或由其他电源供电）测试电机效率，制动器集成在电机法兰中的制动电机包含在本文件中。如果制造商提供有和无制动器的同款电机设计，可在无制动器的电机上进行效率测试，确定的效率可用于有或无制动器的电机效率评级； - 专门设计用于完全浸入液体中运行的潜水电机； - 温度等级高于400 °C的排烟电机。 IEC 60034-30-1 的第二版取消并替换了2014年发布的第一版。此版为技术性修订版。与前一版相比，本次修订包括以下重大技术更改： a）第4条中表1修订，并引入IE5效率； b）为IE5标称效率限值新增表11和表12； c）根据IE5限值修订表13中的插值系数，并将系数范围从0.12 kW至0.75 kW，0.12 kW至0.55 kW。在0.55 kW至0.75 kW范围内应采用线性插值法计算最小效率； d）修订附录A并增加图A.1，展示标称、额定、最低效率及容差。 [外文原描述]： IEC 60034-30-1:2025 specifies efficiency classes for single-speed electric motors that are rated in accordance with IEC 60034‑1 or IEC 60079‑0 and are rated for operation on a sinusoidal either 50 Hz or 60 Hz, or both voltage supply. The motors within this document: - have a rated power PN from 0,12 kW to 1 000 kW; - have a rated voltage UN from 50 V up to and including 1 000 V; - have 2, 4, 6 or 8 poles; - are capable of continuous operation at their rated power with a temperature rise within the specified insulation temperature class; NOTE 1 Most motors covered by this document are rated for duty type S1 (continuous duty). However, some motors that are rated for other duty cycles are still capable of continuous operation at their rated power, and these motors are also covered by this document. - are marked with any ambient temperature within the range of –30 °C to +60 °C; NOTE 2 The rated efficiency and efficiency classes are based on 25 °C ambient temperature in accordance with IEC 60034‑2‑1. NOTE 3 Motors exclusively rated for temperatures outside the range – 30 °C and +60 °C are considered to be of special construction and are consequently excluded from this document. NOTE 4 Smoke extraction motors with a temperature class of up to and including 400 °C are covered by this document. - are marked with an altitude up to 4 000 m above sea level. NOTE 5 The rated efficiency and efficiency class are based on a rating for altitudes up to 1 000 m above sea level. This document establishes a set of nominal efficiency values based on supply frequency, number of poles and motor output power. No distinction is made between motor technologies, supply voltage or motors with increased insulation designed specifically for converter operation even though not all motor technologies are capable of reaching the higher efficiency classes (see Table 1). This makes different motor technologies fully comparable with respect to their energy efficiency potential. The efficiency of power-drive systems is not covered by this document. Motor losses due to harmonic content of the supply voltage, losses in cables, filters and frequency-converters, are not covered. Motors with flanges, feet or shafts with mechanical dimensions different from IEC 60072‑1 are covered by this document. Geared motors are covered by this document including those incorporating non-standard shafts and flanges. This document does not apply to the following: - Single-speed motors with 10 or more poles or multi-speed motors. - Motors with mechanical commutators (such as DC motors). - Motors completely integrated into a machine (for example pump, fan and compressor) that cannot be practically tested separately from the machine even with provision of a temporary end-shield and drive-end bearing. This means the motor: a) shares common components (apart from connectors such as bolts) with the driven unit (for example, a shaft or housing) and b) is not designed in such a way as to enable the motor to be separated from the driven unit as an entire motor that can operate independently of the driven unit. That is, for a motor to be excluded from this document, the process of separation shall render the motor inoperative. - Totally enclosed air-over machines (TEAO, IC418), i.e. totally enclosed frame-surface cooled machines intended for exterior cooling by a ventilating means external to the machine. Efficiency testing of such motors can be performed with the fan removed and the cooling provided by an external blower with a similar airflow rate as the original fan. - Motors with integrated frequency converters (compact drives) when the motor cannot be tested separately from the converter. Energy efficiency classification of compact drives is based on the complete product (PDS, ie. Power Drive System) and is defined in IEC 61800‑9‑2. NOTE 6 A motor is not excluded when the motor and frequency-converter can be separated, and the motor can be tested independently of the converter. - Brake motors when the brake is an integral part of the inner motor construction and can neither be removed nor supplied by a separate power source during the testing of motor efficiency. NOTE 7 Brake motors with a brake coil that is integrated into the flange of the motor are covered as long as it is possible to test motor efficiency without the losses of the brake (for example by dismantling the brake or by energizing the brake coil from a separate power source). When the manufacturer offers a motor of the same design with and without a brake the test of motor efficiency can be done on a motor without the brake. The determined efficiency may then be used as the rating for a motor with or without the brake. - Submersible motors specifically designed to operate wholly immersed in a liquid. - Smoke extraction motors with a temperature class above 400 °C. This second edition of IEC 60034‑30‑1 cancels and replaces the first edition of IEC 60034‑30‑1 published in 2014. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Table 1 in Clause 4 revised and IE5 efficiency introduced. b) New efficiency tables (Table 11 and Table 12) added for IE5 nominal efficiency limits. c) Table 13 for interpolation coefficients revised based on IE5 limits and the coefficients limited from 0,12 kW to 0,75 kW 0,12 kW to 0,55 kW. A linear interpolation shall be applied to obtain minimum efficiency between 0,55 kW and 0,75 kW. d) Annex A revised and added Figure A.1 showing nominal, rated, minimum efficiency and tolerance.
