New approach to evaluate a non-grain oriented electrical steel electromagnetic ...
Rebouças Filho, Pedro Pedrosa; Santos, José Ciro dos; Freitas, Francisco Nélio Costa; Rodrigues, Douglas de Araújo; Ivo, Roberto FernandesThe growing global demand for energy makes it necessary to adopt measures ranging from the exploration of new energy sources to the development of technology for machinery and equipment with greater energy efficiency. Non-grain oriented electrical steels are widely used in the construction of rotors and stators that form the core of electric motors, and their microstructures are directly related to its electrom...

Ivo, Roberto Fernandes; Rodrigues, Douglas de Araújo; Santos, José Ciro dos; Freitas, Francisco Nélio Costa; Herculano, Luís Flávio GasparThis article discusses a fast and efficient classification of non-grain oriented electrical steel and its electromagnetic efficiency based on the analysis of the images of the Crystalline Orientation Distribution Function (CODF). The study was carried out on samples of a non-grain oriented electrical steel, semi-processed with 1.28% silicon, cold rolled with thickness reductions of 50.0% and 70.0%, and annealed...

Rodrigues, Douglas de Araújo; Santos, Gesilane Pereira dos; Fernandes, Marcelo Correia; Santos, José Ciro dos; Freitas, Francisco Nélio CostaThe cast iron has a microstructure in which the shape of the contained graphite has direct influence in the classification between the several types of this material. The classification is usually made through a visual analysis performed by a specialist using an optical microscope. This work proposes the use of Applied Computational Intelligence in conjunction with extractors of information in metallographic im...
