Diese Richtlinie gibt eine Grundlage für die Auswahl drehzahlsteuerbarer Antriebe, inklusive einer gesamtheitlichen Betrachtung der vorgestellten Komponenten bei der neben der energetischen Sicht auch Betriebsweise, Einsatzgebiete und weitere relevante Punkte für die Verwendung dieser angesprochen...
Questa Guida intende descrivere una metodologia per la determinazione del risparmio energetico conseguibile attraverso l'impiego di sistemi elettronici di regolazione di frequenza e di tensione applicati a motori elettrici operanti su sistemi di pompaggio che utilizzano pompe di tipo centrifugo....
INTRODUCTION The Adjustable Speed Drive (ASD) is also known as an Adjustable Frequency Drive (AFD) or Variable Frequency Drive (VFD). ASDs are used in industrial processes that need to control the shaft speed in rotation equipment such as fans, pumps and...
Ciascun componente o sottosistema di un azionamento elettrico a velocità variabile è munito di apposita targa di identificazione, definita dalle Norme ad esso applicabile. La presente Guida fornisce informazioni relative ai modelli di targhe che il fornitore dell'azionamento può applicare...
This document describes a methodology to evaluate energy efficiency performance of pump units based on a non-dimensional numerical value called Energy Efficiency Index (EEI). This document covers pump units consisting of: - one single or several rotodynamic water pump(s), including where integrated...
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 60034-1:2017. The motor is then part of a variable frequency power drive system (PDS) as defined in IEC 61800-9-2:2017....
NOTE: This guide specification covers the requirements for ASD (also referred to as variable frequency drive (VFD)) for motors rated up to 575 volts, for use on electric power systems of 600 volts or less, 50/60 hertz.
Induction Machines Handbook: Transients, Control Principles, Design and Testing presents a practical up-to-date treatment of intricate issues with induction machines (IM) required for design and testing in both rather constant- and variable-speed (with power electronics) drives...
