Annotation of standard text IEC 60034-2-3-ed.1.0 :
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. lIEC 60034-2-3:2020 specifie les methodes d’essai et la procedure d’interpolation relatives a la determination des pertes et des rendements des moteurs alimentes par convertisseur relevant du domaine d’application de l’IEC 60034-1:2017. Le moteur est alors considere comme faisant partie integrante dun systeme d’entrainement electrique de puissance (PDS – power drive system) a frequence variable, comme cela est defini dans l’IEC 61800-9-2:2017. Avec l’approche du convertisseur comparable, le rendement du moteur determine par l’utilisation du present document s’applique uniquement a la comparaison des differentes conceptions de moteurs. Le document specifie egalement des procedures de determination 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) a partir de la determination des pertes au niveau de sept points de charge normalises. Cette procedure s’applique a tout moteur a courant alternatif a vitesse variable (a induction et synchrone) assigne selon l’IEC 60034-1:2017 pour un fonctionnement a frequence variable et alimente en tension variable.
