Dynamics parameters estimation of an asynchronous machine plus mechanical  shaft set through orbit frequency response analysis

Authors

This paper presents some of the results obtained

upon the experimental study of the behaviour of a prototype

mechanical shaft driven by an induction electric machine. The

main focus of this paper will be on the mechanical response of

the set, based on the measurement of a number of mechanical

variables and its integration in well-known mechanical models,

allowing a more accurate estimation of the actual parameters of

the prototype machine. The results thus obtained can then be

used to test the theoretical models, estimate mechanical

parameters more accurately and generally increase knowledge

on the mechanical response of the prototype set.
