Rotating electrical machines – Part 2-3: Specific test methods for determining losses and efficiency of converter-fed AC induction motors
|Publication Date:||1 November 2013|
|ICS Code (Rotating machinery):||29.160|
This technical specification specifies test methods for determining losses and efficiencies of converter-fed AC induction motors within the scope of IEC 60034-1. The AC induction motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800-2, IEC 61800-4 or IEC/TS 61800-8.
The additional harmonic losses determined by use of this technical specification are for comparison of different motor designs, but they are not appropriate to be used for efficiency determination of a PDS in a driven application with its wide range of torque versus speed operating points.
