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 4 of GB/T 25123.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009.
This Part uses redrafting method to modify and adopt IEC 60349-4.2012 "Electric
traction - Rotating electrical machines for rail and road vehicles - Part 4.Permanent
magnet synchronous electrical machines connected to an electronic converter".
Compared with IEC 60349-4.2012, this Part has certain adjustments in structure. Annex
F lists the comparison on Clause numbers between this Part and IEC 60349-4.2012.
There are technical differences between this Part and IEC 60349-4.2012.The margins
of the clauses covered by these differences are marked with a single vertical line (︱).
The technical differences between this Part and IEC 60349-4.2012 and their reasons are
as follows.
- Regarding the normative references, this Part has adjusted 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 identically adopts IEC 60034-1 to replace IEC 60034-1 (see
Clause 1 and Clause 4);
• Use GB/T 1402 that modifies IEC 60850 to replace IEC 60850 (see Annex D);
• Use GB/T 1971 that identically adopts IEC 60034-8 to replace IEC 60034-8 (see
6.2, Annex E);
• Use GB/T 2900.25 that identically adopts IEC 60050-411 to replace IEC 60050-
411 (see Clause 3);
• Use GB/T 2900.36 that modifies IEC 60050-811 to replace IEC 60050-811 (see
Clause 3);
• Use GB/T 2900.74 that modifies IEC 60050-131 to replace IEC 60050-131 (see
Clause 3);
• Use GB/T 2900.83 that identically adopts IEC 60050-151 to replace IEC 60050-
151 (see Clause 3);
• Use GB/T 9637 that not identically adopts IEC 60050-211 to replace IEC 60050-
211 (see Clause 3);
• Use GB 10068 that identically adopts IEC 60034-14 to replace IEC 60034-14
(see 8.5);
• Use GB 10069.3 that identically adopts IEC 60034-9 to replace IEC 60034-9
and move it into the Bibliography, because Annex C of this document is cited
as an informative appendix (see C.8);
• Use GB/T 11021 that identically adopts IEC 60085 to replace IEC 60085 (see
8.1.5);
• Add GB/T 22715 as a reference document (see 9.4.3);
• Delete IEC 62498-1, because it is not directly cited in the text (see Clause 2 and
Clause 4 of IEC 60349-4.2010).
- Modify the requirements for altitude to meet the altitude requirements for traction
equipment in China (see Clause 4 of this document, Clause 4 of IEC 60349-
4.2010);
- Add nameplates to increase important parameters (see 6.1 of this document, 6.1 of
IEC 60349-4.2010);
- Delete the additional temperature rise test of the converter power supply in the
simplified type inspection, so as to improve the inspection requirements (see 7.3.2
of IEC 60349-4.2010);
- Add assessment test of anti-demagnetization ability to improve the reliability of the
permanent magnet motor (see 8.2);
- Modify the loss tolerance requirements so as to be consistent with the loss tolerance
of GB/T 25123.2 (see 8.3.2 of this document, 8.2.2 of IEC 60349-4.2010);
- Modify "9.4 Withstanding voltage test" and change it to "9.4 Insulation test". Add
"9.4.1 Insulation resistance measurement of stator windings" and "9.4.3 Impulse
withstand voltage level of stator coil" to improve product quality (see 9.4 of this
document, 9.4 of IEC 60349-4.2010).
This Part also makes the following editorial changes.
- Add Note 4 of 5.1 to comply with the provisions of GB/T 1.1-2009;
- Modify the title of 8.7 (7.3 of IEC 60349-4.2010) "Simplified type inspection" to
"Additional temperature rise test";
- Modify the citation error in C.1.2;
- Adjust the figure sequence in Annex C;
- Modify the typesetting of Annex E and change it to a table to conform to Chinese
habits;
- Add informative Annex F to explain structural adjustments;
- Modify the Bibliography.
