A Study on the Down‐Scaling of Transient Drive Cycles for Experimental Analyses With Laboratory Based Small Motors

open access: yesIET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
A new down‐scaling method for the laboratory based analysis of transient drive cycles is proposed and analysed. In contrast to the typically used dimensionless per unit steady‐state operating‐point based scaling methods, this approach also considers information on the cycles' transient characteristics in the scaling process. ABSTRACT Standardised drive
