欧盟电机能效标准（中英文）

DIN和欧盟标准的最终版本基于IEC标准；在关于实施适用于特定类型电机的 2009/125/EC 指令的欧盟条例中，对欧盟标准的最小值进行了规定。

The final versions of the DIN and European standards are based on the IEC standard; the minimum values of the EN standard are specified in an EU regulation regarding the implementation of Directive 2009/125/EC for selected types of motors.

等级代码 / Class codes

IE1、IE2、IE3 与 IE4 等级代码现已推出。这一体系与多年来电动机械行业所使用的 IP、IM 与 IC 代码相似。IE 指“国际能源效率等级”，有望获得广泛认可。

IE效率等级

• IE1 = 标准效率

• IE2 = 高效率

• IE3 = 卓越效率

• IE4 = 超级高效

• IE5 =（未定义特定名称）

Class codes IE1, IE2, IE3 and IE4 have been introduced. This system is similar to the IP, IM and IC codes uses for many years in the electrical machinery industry. IE stands for ‚International Energy Efficiency Class‘ and is widely accepted.

IE efficiency classes

• IE1 = Standard Efficiency

• IE2 = High Efficiency

• IE3 = Premium Efficiency

• IE4 = Super Premium Efficiency

• IE5 = (no specific name defined)

效率等级比较 / Comparison of efficiency classes

能效等级的提高主要是通过使用更多活性材料的异步技术实现的。随着效率的每次提高，电机机架长度都会发生变化，并且如果需要，电机机架尺寸也会发生变化。为避免电机尺寸跳跃，可以使用各种优化选项，例如通过调整绕组增加槽填充、使用更高质量的电气叠片以及在必要时使用铜作为笼式转子材料。

该图显示了法规 (欧盟) 2019/1781 范围内 IE2 至 IE4 电机的功率相关效率曲线。

IEC 60034-30-1 分类要求的例外情况

• 运行模式 S2、S3<80 %、S4 至 S10

• 不能直接由电源供电的变频驱动电机。

• 无法独立测量的电机，例如带有湿转子的泵电机。

The increase in energy efficiency class is primarily achieved with asynchronous technology by using more active materials. With each increase in efficiency, the motor frame length changes and, if necessary, the motor frame size also changes. To avoid motor size jumps, various optimization options are available, such as increasing the slot fillings by means of adapted windings, use of higher-quality electrical laminations and, if necessary, copper as cage rotor material.

The diagram shows the power-dependent efficiency curves of IE2 to IE4 motors from the scope of Regulation (EU) 2019/1781.

Exceptions to the classification requirement IEC 60034-30-1

• Operating mode S2, S3<80 %, S4 to S10

• Inverter-driven motors that cannot be operated directly from the mains.

• Motors that cannot be independently measured, such as pump motors with wet rotors.

关于新技术的超高级 IE4/IE5 / Super Premium class IE4/IE5 for new technology

该效率等级在IEC 60034-30-1标准中针对直接在线操作交流电机和 IEC TS 60034-30-2 中针对变速交流电机进行了描述。在IEC TS 60034-30-2中，也首次规定了效率等级IE5的最低效率。

效率等级IE4适用于所有类型的线路操作交流电动机。用于变频供电的Bauer永磁同步电机的效率等级源自IEC TS 60034-30-2中描述的效率等级IE4/IE5。这些电机通常按扭矩而不是功率进行额定。总效率的确定考虑了逆变器中的功率耗散以及通过速度控制实现的通常相当可观的过程增益。因此，直接比较直线电机和变速电机没有意义。

This efficiency class is described in the IEC 60034-30-1 standard for direct online operated AC motors and in the IEC TS 60034-30-2 for variable speed AC motors. In IEC TS 60034-30-2, minimum efficiencies for efficiency class IE5 are also specified for the first time.

Efficiency Class IE4 applies to all types of line operated AC electric motors. The efficiency class of Bauer permanent magnet synchronous motors for inverter supply have been derived from the efficiency class IE4/IE5 described in IEC TS 60034-30-2. These motors are generally rated by torque rather than power. The overall efficiency is determined taking into account the power dissipation in the inverter and the often considerable process gains achieved with speed control. A direct comparison of line operated motors and variable speed motors is therefore not meaningful.
