Análise da dinâmica acoplada de um motor de indução trifásico montado sobre uma base elástica

Abstract

The dynamic analysis of systems compound by electric motor and its support structure its very important, because there is an interaction between them and the mutual influence generate various phenomena during its operation. With mathematical models is possible to simulate the dynamical behavior of these systems, with the objective of represent an actual condition and to predict the system response. These answers provide information that can be applied in solutions to the problems during project stage and assist failure analysis. In recent years, the drives based in Direct Current Motors (DCM) have been gradually substituted by drives based in Alternate Current Three-phase Induction Motor (TIM). The coupled dynamic analysis of DCM and its structure base have been widely studded and the phenomena that occur modeled. The objective of this study is to analyze the systems compound by an elastic base support and a three-phase induction motor by coupled dynamic models, to identify and verify if non-linear oscillation phenomena are relevant to this type of motor.
