Foreword
GB/T 25123 Electro Traction – Rotating Electrical Machines for Rail and Road Vehicles
consists of the following parts:
--- Part 1: Machines others than Electronic Convertor-Fed Alternating Current Motors
--- Part 2: Electronic Convertor-Fed Alternating Current Motors;
--- Part 3: Determination of the Total Losses of Convertor-Fed Alternating Current Motors
by Summation of the Component Losses;
--- Part 4: Permanent Magnet Synchronous Electrical Machines Connected to an Electronic
Converter.
This Part is Part 2 of GB/T 25123.
This Part was drafted as per the rules stipulated in GB/T 1.1-2009.
This Part replaced GB/T 25123.2-2010 Electric Traction - Rotating Electrical Machines for
Rail and Road Vehicles - Part 2: Electronic Convertor-Fed Alternating Current Motors.
Compared with GB/T 25123.2-2010, the major technical changes of this Part are as follows:
--- Add the content of "Further tests can be selected in accordance with GB/T 25117.1 and
GB/T 25117.3. In order to avoid the test repeating, some type inspection items and
research test items are best carried out on the combined test bench." (See 1.1 of this
Edition);
--- Modify the regulations on altitude and ambient temperature. In Clause 4, the altitude and
ambient temperature, etc., are changed from the original direct regulations to as per GB/T
32347.1-2015 (see Clause 4 of this Edition; Clause 4 of the 2010 Edition);
--- Modify the name of the insulation class into "insulation system thermal grading"; and
each class is marked with numbers, such as 130(B), 155(F), 180(H) (see 8.1.5, 8.1.6 of
this Edition; 8.1.4, 8.1.6 of the 2010 Edition);
--- Modify the content of traction motor vibration limit. Since in GB/T 10068-2008, the limit
value of vibration velocity has been changed, this edition has been modified accordingly.
And add the subclause of "do not assess the axial vibration velocity of the motor without
fixed bearing structure" (see 8.4 of this Edition; 8.4 of the 2010 Edition);
--- Modify the optional methods and standards for noise measurement (see D.1 of this
Edition; C.1 of the 2010 Edition).
This Part uses redrafting method to modify and adopt IEC 60349-2:2010 Electric Traction –
Rotating Electrical Machines for Rail and Road Vehicles – Part 2: Electronic Converter-Fed
Alternating Current Motors.
Compared with IEC 60349-2:2010, this Part made certain adjustment in structure; and the
specific adjustments are as follows:
--- Modify the serial number of the subclauses in Clause 1; and add the title of the subclause;
--- Add 8.5 "noise measurement";
--- Modify the serial number of subclauses in 9.3.1, adding 9.3.1.1~9.3.1.3;
--- Modify the serial number of subclauses in 9.3.2, adding 9.3.2.1~9.3.2.3;
--- Modify the serial number of subclauses in C.3, adding C.3.1 and C.3.2;
--- Modify the serial number of subclauses in D.1, adding D.1.1~D.1.6;
--- Modify the serial numbers of subclauses in Annex E, adjusting E.1, E.2, and E.3 into
Table E.1;
--- Modify the serial number of Annex, adjusting Annex A into Annex C, Annex C into
Annex D, Annex D into Annex A.
There are technical differences between this Part and IEC 60349-2:2010. The terms involved
in these differences have been marked by a vertical single line (|) in the outer margin position.
The specific technical differences and their reasons are as follows:
--- Regarding the Normative References, this Part has made adjustments with technical
differences to adapt to the technical conditions of China. The adjustments are reflected
in Clause 2 "Normative References". The specific adjustments are as follows:
 Use GB/T 755 that equivalently adopts the international standard to replace IEC
60334-1 (see 1.4, Clause 4);
 Use GB/T 1971 that equivalently adopts the international standard to replace IEC
60334-8 (see 6.2, Table E.1);
 Use GB/T 2900.25 that equivalently adopts the international standard to replace IEC
60050-411 (see Clause 3);
 Use GB/T 2900.36 that modifies and adopts the internationals standard to replace
IEC 60050 (811) (see Clause 3);
 Use GB/T 2900.74 that modifies and adopts the international standard to replace
IEC 60050-131 (see Clause 3);
 Use GB/T 2900.83 that equivalently adopts the international standard to replace IEC
60050-151 (see Clause 3);
 Use GB/T 11021 that equivalently adopts the international standard to replace IEC
60085 (See 8.1.5);
 Use GB/T 32347.1-2015 that modifies and adopts the international standard to
replace IEC 62498-1:2010 (see Clause 4);
 Add the quotation of GB/T 1402, GB/T 25117.1, GB/T 25117.3 (see 1.1, Annex A);
 Delete IEC 60034-9, IEC 60034-17, IEC 61672, which are transferred to the
Bibliography.
--- Modify the environmental conditions, the altitude and temperature are quoted from GB/T
32347.1-2015 Railway Applications - Environmental Conditions for Equipment - Part 1:
Equipment on Board Rolling Stock (see Clause 4);
--- Add the specific parameter information provided by the designer of the asynchronous
traction motor (see 5.1);
--- Change the NOTE in 6.1 into the text (see 6.1);
--- Add the static pressure head requirements at rated air volume (see 8.1.2);
--- Add test items and modify the contents of Table 1. These test items include: noise
measurement (see 8.5), measurement of winding cold-state DC resistance (see 9.7),
inspection of wiring marks and rotation direction (see 9.8);
--- The footnotes in Table 2 to adapt to the actual situation in China (see 8.1.5);
--- Modify Annex E to be informative (see Annex E).
This Part made the following editorial modifications:
--- Modify the title of Clause 7 (see Clause 7);
--- Modify the format and content of Table 1; and list the noise test in Table 1 as a type
inspection item separately (see 7.2, 8.5);
--- Modify the name of "electrical machine" into "electric motor" (see 8.2.1, Annex D);
--- Modify the title of 9.5, that is, change "dielectric test" into "winding-to-earth withstand
voltage test" (see 9.5);
--- Delete the NOTE (see 9.5);
--- Modify the name of the vibration test (see 9.6);
--- Add "Note: Annex E gives the content of negotiation between the supplier and the
purchaser " to quote Annex E (see Clause 9);
