歐盟電機(jī)能效標(biāo)準(zhǔn)（中英文）
DIN和歐盟標(biāo)準(zhǔn)的最終版本基于IEC標(biāo)準(zhǔn)；在關(guān)于實(shí)施適用于特定類型電機(jī)的 2009/125/EC 指令的歐盟條例中，對(duì)歐盟標(biāo)準(zhǔn)的最小值進(jìn)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(jí)代碼 / Class codes
IE1、IE2、IE3 與 IE4 等級(jí)代碼現(xiàn)已推出。這一體系與多年來電動(dòng)機(jī)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(jí)”，有望獲得廣泛認(rèn)可。
IE效率等級(jí)
? IE1 = 標(biāo)準(zhǔn)效率
? IE2 = 高效率
? IE3 = 卓越效率
? IE4 = 超級(jí)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(jí)比較 / Comparison of efficiency classes
能效等級(jí)的提高主要是通過使用更多活性材料的異步技術(shù)實(shí)現(xiàn)的。隨著效率的每次提高，電機(jī)機(jī)架長度都會(huì)發(fā)生變化，并且如果需要，電機(jī)機(jī)架尺寸也會(huì)發(fā)生變化。為避免電機(jī)尺寸跳躍，可以使用各種優(yōu)化選項(xiàng)，例如通過調(diào)整繞組增加槽填充、使用更高質(zhì)量的電氣疊片以及在必要時(shí)使用銅作為籠式轉(zhuǎn)子材料。
該圖顯示了法規(guī) (歐盟) 2019/1781 范圍內(nèi) IE2 至 IE4 電機(jī)的功率相關(guān)效率曲線。
IEC 60034-30-1 分類要求的例外情況
? 運(yùn)行模式 S2、S3<80 %、S4 至 S10
? 不能直接由電源供電的變頻驅(qū)動(dòng)電機(jī)。
? 無法獨(dú)立測量的電機(jī)，例如帶有濕轉(zhuǎn)子的泵電機(jī)。
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(guān)于新技術(shù)的超高級(jí) IE4/IE5 / Super Premium class IE4/IE5 for new technology
該效率等級(jí)在IEC 60034-30-1標(biāo)準(zhǔn)中針對(duì)直接在線操作交流電機(jī)和 IEC TS 60034-30-2 中針對(duì)變速交流電機(jī)進(jìn)行了描述。在IEC TS 60034-30-2中，也首次規(guī)定了效率等級(jí)IE5的最低效率。
效率等級(jí)IE4適用于所有類型的線路操作交流電動(dòng)機(jī)。用于變頻供電的Bauer永磁同步電機(jī)的效率等級(jí)源自IEC TS 60034-30-2中描述的效率等級(jí)IE4/IE5。這些電機(jī)通常按扭矩而不是功率進(jìn)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(shí)現(xiàn)的通常相當(dāng)可觀的過程增益。因此，直接比較直線電機(jī)和變速電機(jī)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.
