Drehende elektrische Maschinen - Teil 28: Prüfverfahren zur Bestimmung der Ersatzschaltbildgrößen dreiphasiger Niederspannungs-Käfigläufer-Asynchronmotoren (IEC 60034-28:2012); Deutsche Fassung EN 60034-28:2013
Overview
This part of the series VDE 0530 applies to three-phase low-voltage cage induction motors of frame numbers 56 to 400. This standard establishes procedures to obtain values for elements of single phase equivalent circuit diagrams from tests and defines standard elements of these equivalent circuit diagrams. Equivalent circuit diagrams are widely used in the control of adjustable speed drives with induction motors supplied by frequency inverters. The motor parameters are required for the realization of flux oriented control or other model-based control algorithms. Their knowledge is required by suppliers and system engineers, especially when motors and frequency inverters from different suppliers are combined. This standard provides a standardized test procedure to determine the electric motor parameters. At the same time this document offers an improved understanding of the equivalent circuit method. The procedures can be carried out in test facilities equipped for standard electric machinery tests. The responsible body is DKE/K 311 "Drehende elektrische Maschinen" ("Rotating electrical machines") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
