Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 20114-2006 "Special test method for ordinary power supply or rectifier power supply DC motor". With GB/T
Compared with.20114-2006, the main technical changes are as follows.
--- Added terms, definitions, symbols and subscripts (see Chapter 3);
--- Explain in more detail the non-sparking commutation zone test procedure (see Chapter 7);
--- Increased and (he) excitation adjustment curve test procedure (see Chapter 11);
--- Increased the magnetization curve test procedure under no-load and load conditions (see Chapter 12).
This standard uses the translation method equivalent to IEC 60034-19.2014 "Rotating electrical machines Part 19. General power supply or rectifier power supply
Special Test Method for DC Motors.
The documents of our country that have a consistent correspondence with the international documents referenced in this standard are as follows.
---GB/T 755-2008 Rotating electrical machine rating and performance (IEC 60034-1.2004, IDT);
---GB/T 25442-2018 Rotating electrical machines (except traction motors) - Test methods for determining loss and efficiency (IEC 60034-2-1.
2014, IDT).
This standard makes the following editorial changes.
--- The standard name was changed to "Special Test Method for DC Motors for Common Power Supply or Rectifier Power Supply".
This standard was proposed by the China Electrical Equipment Industry Association.
This standard is under the jurisdiction of the National Rotating Electric Machine Standardization Technical Committee (SAC/TC26).
