Análise de projeto, acionamento e desempenho dinâmico do motor síncrono de relutância através de simulação computacional

Abstract

This work addresses the Synchronous Reluctance Motor from the constructive, operational and operational aspects through computational simulation. The first models of this engine were designed in the early 20th century. The popularization of SynRM became possible due to the advancement of construction techniques, operation in ferromagnetic materials and high performance microprocessed systems. Based on this, the present work approaches SynRM under the characteristics of design and dynamic performance tests and tests in computational environment. Thus, a finite element study is carried out, taking into account different generations of SynRM rotors that allow defining the best rotor geometry according to the magnetic flux distribution. In addition, the electrical and mechanical models are implemented in a computational environment and real application scenarios such as speed ramp and load step driving are implemented in the simulation environment. Computer simulation of the engine allows it to be studied under different points of application and operation that validate performance comparisons between SynRM geometry models and in relation to other engines on the market. The results obtained are presented and the dynamic performance of the engine is evaluated through the response to speed variation, insertion or removal of load on the shaft.
