Simulação digital do comportamento de um motor síncrono submetido a cargas mecânicas variáveis.

Abstract

Rotating electrical machines are the most used equipment for electromechanical energy conversion.. For this reason, they are studied in various disciplines from graduation in electrical engineering, where the emphasis is on their continuous operation. However, it is equally indisputable relevance of the analysis of these machines in transitional arrangements, which led this research. In this work is examined by digital simulation, the performance of a synchronous motor on transitional arrangements, when subjected to a mechanical load on its axis. To do this, the engine descriptive differential equations in review are developed in addition to the algorithm necessary to resolve, developed based on numerical integration method and encoded into computer language the data obtained for the various engine physical quantities are shown in numerical and graphical forms, and confronted with the values obtained for that machine working permanently. It is noteworthy that although this study is concerning a particular load, the generality of the method enables your application to more general situations involving the dynamic effect of any mechanical load added to the motor shaft. Therefore, the results obtained satisfactorily met the purposes of this research.
