26、tion of energy-efficiency classes for electric motors. Electric motor applications in industry consume between 30 % and 40 % of the generated electrical energy worldwide. Improving efficiency of the complete drive system (i.e. motor and adjustable-speed drives) including the application (or process)
27、 is therefore a major concern in energy-efficiency efforts. The total energy saving potential of an optimized system is assumed to be around 30 % to 60 %. According to the findings of the IEA 7 July 2006 Motor Workshop, electric motors with improved efficiency in combination with frequency converter
28、s can save about 7 % of the total worldwide electrical energy. Roughly one quarter to one third of these savings come from the improved efficiency of the motor. The remaining part results from system improvements. Many different energy efficiency standards for cage induction motors are already in us
29、e (NEMA, EPACT, CSA, CEMEP, COPANT, AS/NZS, JIS, GB and others) with new classes currently being developed. It becomes increasingly difficult for manufacturers to design motors for a global market and for customers to understand differences and similarities of standards in different countries. Motor
30、s from 0,75 kW up to 375 kW make up the vast majority of installed motor population and are covered by this standard as shown in Figure 1.

32、ential by installed motors in the industrial sector In some countries smaller motors are included in energy efficiency regulations. Most of these motors are not three-phase, cage-induction machines. Also they typically do not run continuously so their energy saving potential is rather limited. In so
33、me countries 8-pole motors are included in energy efficiency regulations. However, their market share is already very low (1 % or less). Due to increasing acceptance of variable-speed drives and the low cost associated with 4- and 6-pole standard motors it is expected that 8-pole motors will even fu
34、rther disappear from the general market in the future. Therefore, this standard does not include provisions for 8-pole motors. BS EN 60034-30:2009Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 03/09/2009 04:08, Uncontrolled Copy, (c) BSI 6 60034-30 IEC:2008 For a given output power and frame
35、 size it is generally easier to reach a high motor efficiency when the motor is designed for and operated at 60 Hz mains supply frequency rather than at 50 Hz. NOTE 1 As the utilization and size of motors are related to torque rather than power the theoretical output power increases linearly with sp
36、eed, i.e. by 20 % from 50 Hz to 60 Hz. IR winding-losses are dominant especially in small and medium sized induction motors. They basically remain constant for 50 Hz and 60 Hz as long as the torque is kept constant. Although windage, friction and iron losses increase with frequency, they play a mino
37、r role in these motors. Therefore, at 60 Hz, the losses increase less than the 20 % output-power increase compared to 50 Hz and the efficiency improves. In practice, both 60 Hz and 50 Hz output power designations should conform to standard power levels in accordance with IEC 60072-1 and local standa
38、rds like EN 50347. Therefore, an increased rating of motor power by 20 % is not always possible. However, the general advantage of 60 Hz still applies if the motor design is optimized for the respective supply frequency rather than just re-rated. The difference in efficiency between 50 Hz and 60 Hz
39、varies with the number of poles and the size of the motor. In general, the 60 Hz efficiency of three-phase, cage-induction motors in the output power range from 0,75 kW up to 375 kW is between 2,5 % to less than 0,5 % points greater when compared to the 50 Hz efficiency. Only large 2-pole motors may
40、 experience a reduced efficiency at 60 Hz due to their high share of iron, windage and friction losses. In this standard, the nominal 50 Hz limits of Standard (IE1) and High Efficiency (IE2) are based on the CEMEP-EU EFF2 and EFF1 limits respectively. However, they have been adjusted to take the dif
41、ferent test procedures into account (CEMEP: Additional load losses PLLflat 0,5 % of input power; in this standard PLLis determined from test). The nominal 50 Hz limits for Premium Efficiency (IE3) are set with the losses about 15 % to 20 % lower compared to the limits for High Efficiency (IE2). The
42、nominal 60 Hz limits for Standard Efficiency (IE1) are identical to Brazilian regulations. The nominal 60 Hz limits for High Efficiency (IE2) and for Premium Efficiency (IE3) are identical to US American EPAct regulations. A new Super-Premium class (IE4) is envisaged for future editions of this stan
43、dard. It is not expected that all manufacturers will produce motors for all efficiency classes or all ratings for a given class. Users should select the efficiency class in accordance with the application depending on the actual operating hours. It may not be energy efficient to select High- or Prem
44、ium-Efficiency motors for intermittent or short-time duty. NOTE 2 An application guide with more details is planned to be released as an IEC publication soon. In order to achieve a significant market share it is essential for high-efficiency motors to meet national/regional standards for assigned ou
45、tput powers in relation to mechanical dimensions (frame-size, flanges, etc.). There are a number of national/regional frame assignment standards (EN 50347, JISC 4212, NBR 7094, NEMA MG1, SANS 1804 and others) but there is no IEC standard. As this standard (IEC 60034-30) defines energy-efficiency cla
46、sses independent of dimensional constraints it may not be possible in all markets to produce motors with higher efficiency classes and maintain the mechanical dimensions of the national/regional standards. Regulators should consider the above constraints as well as the field of applications as detai
47、led in Clause 4 when assigning minimum energy-efficiency performance standards (MEPS).
