DS IEC/TS 60349-3:2010

Tërheqja elektrike - Makinat elektrike rrotulluese për automjetet hekurudhore dhe rrugore - Pjesa 3: Përcaktimi i humbjeve totale të motorëve me rrymë alternative që ushqehen me converter nëpërmjet shumatores së humbjeve të komponentëve

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

Scope

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.
