Rotating electrical machines - Specific test methods for determining losses and efficiency of converter-fed AC motors Ingestion-build-137917 Annex B (normative) Guidance on1 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
