IEC 60034-19-2014 Rotating electrical machines - Part 19: Specific test methods for d.c. machines on conventional and rectifier-fed supplies

Language: English, French
International Standard IEC 60034-19 has been prepared by IEC technical committee 2: Rotating machinery.
This second edition cancels and replaces the first edition published in 1995. It constitutes a technical revision. The main technical changes with regard to the previous edition are as follows:
a) The description of the procedure for black band testing has been detailed and clarified.
b) Procedures for measurement of the magnetization curves under no-load and load conditions have been added.Scope
This part of IEC 60034 applies to d.c. machines rated 1 kW and above operating on rectifierfed power supplies, d.c. buses or other d.c. sources.
Standardized methods are provided for determining characteristic quantities for conventional and rectifier-fed d.c. machines.
Excluded are d.c machines for specific applications.
These methods supplement the requirements in IEC 60034-1 and IEC 60034-2-1.
NOTE It is not intended that this standard should be interpreted as requiring the carrying out of any or all of the tests described therein on any given machine.
