Rotating electrical machines - Part 2-3: Specific test methods for determining losses and efficiency of converter-fed AC motors
IEC 60034-2-3:2020 specifies test methods and an interpolation procedure for determining losses and efficiencies of converter-fed motors within the scope of IEC 60034-1:2017. The motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800‑9‑2:2017. Applying the approach of the comparable converter, the motor efficiency determined by use of this document is applicable for comparison of different motor designs only. The document also specifies procedures to determine motor losses at any load point (torque, speed) within the base speed range (constant torque range, constant flux range) based on determination of losses at seven standardized load points. This procedure is applicable to any variable speed AC motor (induction and synchronous) rated according to IEC 60034-1:2017 for operation on a variable frequency and variable voltage power supply.

Machines électriques tournantes - Partie 2-3: Méthodes d'essai spécifiques pour la détermination des pertes et du rendement des moteurs à courant alternatif alimentés par convertisseur
l'IEC 60034-2-3:2020 spécifie les méthodes d’essai et la procédure d’interpolation relatives à la détermination des pertes et des rendements des moteurs alimentés par convertisseur relevant du domaine d’application de l’IEC 60034-1:2017. Le moteur est alors considéré comme faisant partie intégrante d'un système d’entraînement électrique de puissance (PDS – power drive system) à fréquence variable, comme cela est défini dans l’IEC 61800-9-2:2017. Avec l’approche du convertisseur comparable, le rendement du moteur déterminé par l’utilisation du présent document s’applique uniquement à la comparaison des différentes conceptions de moteurs. Le document spécifie également des procédures de détermination des pertes du moteur en tout point de charge (couple, vitesse) dans la plage de vitesses de base (plage de couples constants, plage de flux constants) à partir de la détermination des pertes au niveau de sept points de charge normalisés. Cette procédure s’applique à tout moteur à courant alternatif à vitesse variable (à induction et synchrone) assigné selon l’IEC 60034-1:2017 pour un fonctionnement à fréquence variable et alimenté en tension variable.
