歐盟電機能效標準（中英文）
DIN和歐盟標準的最終版本基于IEC標準；在關于實施適用于特定類型電機的 2009/125/EC 指令的歐盟條例中，對歐盟標準的最小值進行了規(guī)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.
等級代碼 / Class codes
IE1、IE2、IE3 與 IE4 等級代碼現(xiàn)已推出。這一體系與多年來電動機械行業(yè)所使用的 IP、IM 與 IC 代碼相似。IE 指“國際能源效率等級”，有望獲得廣泛認可。
IE效率等級
? IE1 = 標準效率
? IE2 = 高效率
? IE3 = 卓越效率
? IE4 = 超級高效
? IE5 =（未定義特定名稱）
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)
效率等級比較 / Comparison of efficiency classes
能效等級的提高主要是通過使用更多活性材料的異步技術實現(xiàn)的。隨著效率的每次提高，電機機架長度都會發(fā)生變化，并且如果需要，電機機架尺寸也會發(fā)生變化。為避免電機尺寸跳躍，可以使用各種優(yōu)化選項，例如通過調整繞組增加槽填充、使用更高質量的電氣疊片以及在必要時使用銅作為籠式轉子材料。
該圖顯示了法規(guī) (歐盟) 2019/1781 范圍內 IE2 至 IE4 電機的功率相關效率曲線。
IEC 60034-30-1 分類要求的例外情況
? 運行模式 S2、S3<80 %、S4 至 S10
? 不能直接由電源供電的變頻驅動電機。
? 無法獨立測量的電機，例如帶有濕轉子的泵電機。
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.
關于新技術的超高級 IE4/IE5 / Super Premium class IE4/IE5 for new technology
該效率等級在IEC 60034-30-1標準中針對直接在線操作交流電機和 IEC TS 60034-30-2 中針對變速交流電機進行了描述。在IEC TS 60034-30-2中，也首次規(guī)定了效率等級IE5的最低效率。
效率等級IE4適用于所有類型的線路操作交流電動機。用于變頻供電的Bauer永磁同步電機的效率等級源自IEC TS 60034-30-2中描述的效率等級IE4/IE5。這些電機通常按扭矩而不是功率進行額定?？傂实拇_定考慮了逆變器中的功率耗散以及通過速度控制實現(xiàn)的通常相當可觀的過程增益。因此，直接比較直線電機和變速電機沒有意義。
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.
