Rotating electrical machines - Part 4: Methods for determining synchronous machine quantities from tests
IEC 60034-4:2008 applies to three-phase synchronous machines of 1 kVA rating and larger with rated frequency of not greater than 500 Hz and not less than 10 Hz. The main changes with respect to the previous edition are as follows:- removal of certain tests for lack of relevance in current practise;- addition of provisions for tests on machines with brushless excitation;- addition of a table of test methods indicating preferred tests and cross-references.

Rotating electrical machines. Part 4: Methods for determining synchronous machine quantities from tests
Applies to three-phase synchronous machines of 1 kVA rating and larger with rated frequency of not more than 400 Hz and not less than 15 Hz. An appendix gives unconfirmed test methods for determining synchronous machine quantities. Notes: 1 -Tests are not applicable to synchronous machines such as permanent magnet field machines, inductor type machines, etc. 2 -They also apply to brushless machines, but certain variations exist and special precautions should be taken.

Rotating electrical machines - Part 4-1: Methods for determining electrically excited synchronous machine quantities from tests
IEC 60034-4-1:2018 applies to three-phase synchronous machines of 1 kVA rating and larger and describes methods intended to be used for machines having an excitation winding with slip-rings and brushes for their supply. Synchronous machines with brushless excitation require special effort for some of the tests. For machines with permanent magnet excitation, there is a limited applicability of the described tests, and special precautions should be taken against irreversible demagnetization.
