It deals with all k

28、inds of electric motors that are rated for line operation (including starting at reduced voltage). This includes all single- and three-phase low voltage induction motors, regardless of their rated voltage and frequency, as well as line-start permanent-magnet motors. A second part of this standard se

29、ries (IEC 60034-30-2) will be prepared for motors rated for variable voltage and frequency supply, such as synchronous motors. The second part will also provide for harmonic voltage losses in motors capable of line operation when fed by frequency converters. IEC 60034-30-1 widens the product range c

30、overed in the first edition of IEC 60034-30 significantly. The power range has been expanded (starting at 0,12 kW and ending at 1 000 kW). All technical constructions of electric motors are covered as long as they are rated for on-line operation and not just three-phase, cage-induction motors as in

31、the first edition. The IE4 class is newly included in this standard. The informative definition of IE4, which was previously included in IEC/TS 60034-31:2010, is therefore outdated. The new class IE5 is not yet defined in detail but is envisaged for potential products in a future edition of the stan

32、dard. For a given power and frame size it is generally easier to achieve a higher motor efficiency when the motor is designed for and operated directly on-line with a 60 Hz supply frequency rather than on 50 Hz as explained in Note 1. NOTE 1 As the utilization and size of motors are related to torqu

33、e rather than power the theoretical power of single-speed motors increases linearly with supply frequency (and hence with speed), i.e. by 20 % from 50 Hz to 60 Hz. I2R winding-losses are dominant especially in small and medium sized induction motors. They basically remain constant at 50 Hz and 60 Hz

34、 as long as the torque is kept constant. Although windage, friction and iron losses increase with frequency, they play a minor role especially in motors with a number of poles of four and higher. Therefore, at 60 Hz, the losses increase less than the 20 % power increase when compared to 50 Hz and co

35、nsequently, the efficiency is improved. In practice, both 60 Hz and 50 Hz power designations of single-speed motors have to conform to standard power levels in accordance with IEC 60072-1 and local standards such as EN 50347. Therefore, an increased rating of motor power by 20 % is not always possib

36、le. However the general advantage of 60 Hz still applies when 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 varies with the number of poles and the size of the motor. In general, the 60 Hz efficiency

37、of three-phase, cage-induction motors in the power range from 0,75 kW up to 375 kW is between 2,5 percentage points to less than 0,5 percentage points greater when compared to the 50 Hz efficiency. Only large 2-pole motors may experience a reduced efficiency at 60 Hz due to their high share of iron,

38、 windage and friction losses. It is not expected that all manufacturers will produce motors for all efficiency classes nor all ratings of a given class. Users should select the efficiency class in accordance with a given application depending on the actual operating hours. It may not be energy effic

39、ient to select motors of a high efficiency class for intermittent or short time duty due to increased inertia and start-up losses. NOTE 2 The application guide IEC/TS 60034-31:2010 gives further information on useful applications of high-efficient electric motors. In order to achieve a significant m

40、arket share it is essential for high-efficiency motors to meet national/regional standards for assigned powers in relation to mechanical dimensions (such as frame-size, flanges). There are a number of national/regional frame assignment standards (EN 50347, JIS C 4212, NBR 17094, NEMA MG13, SANS 1804

41、 and others) but there is no BS EN 60034-30-1:2014 6 IEC 60034-30-1:2014 IEC 2014 IEC standard. As this standard (IEC 60034-30-1) defines energy-efficiency classes independent of dimensional constraints it may not be possible in all markets to produce motors with higher efficiency classes and mainta

42、in the mechanical dimensions of the national/regional standards. IE codes are not limited to motors but may be used to classify other components such as frequency converters and gearboxes. However, it is anticipated that other components are rated with a comparable system: IE1 meaning low efficiency

43、 up to IE5 meaning the highest efficiency. Combinations of components (such as power drive systems) will need a combined efficiency rating. That rating should not be an IE code in order to avoid confusion. It will be defined in other IEC standards. The efficiency levels in this standard for 50 Hz an

44、d 60 Hz are not always entirely consistent across all numbers of poles and over the whole power range. NOTE 3 The efficiency levels for 60 Hz motors were assigned for compatibility with U.S. legal requirements. NOTE 4 The efficiency levels for 50 Hz motors between 0,75 kW and 375 kW remain unchanged

45、 for compatibility with European legal requirements.

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 cov

NOTE 3 Motors rated for temperatures outside the range 20 C and + 60 C are considered to be of specia

NOTE 4 Smoke extraction motors with a temperature class of up to and including 400 C are covered by this standard. 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 standard establishes a set of limit efficiency values based on frequency, number of poles and motor power. No distinction is
