IEC Technical Specification 60349-3
IEC TS 60349-3:2010
Electric traction - Rotating electrical machines for rail and road vehicles - Part 3: Determination of the total losses of converter-fed alternating current motors by summation of the component losses
IEC/TS 60349-3:2010 applies to machines complying with IEC 60349-2. The losses supplied at the fundamental frequency cannot be measured directly and so are derived from measurement of the fundamental frequency load current and the fundamental frequency no-load power input. The main technical changes with regard to the previous edition are corrections in some formulas in 3.2.1.2 and in Table A.2.
