Rotating electrical machines - Specific test methods for determining losses and efficiency of converter-fed AC motors Ingestion-build-137917 Anyone responsible for the installation1 Scope This part of IEC 60034 specifies test methods and an interpolation procedure for determining losses and efficiencies of converter fed motors within the scope of IEC 600341: 2017. The motor is then part of a variable frequency power drive system (PDS) as defined in IEC 6180092: 2017. Applying the approach of the comparable converter, the motor efficiency determined by use of this document is applicable for comparison of different motor designs
