Análise dinâmica da potência requerida para o motor de um moinho para plástico de uma empresa especializada na produção de sacos para lixo localizada na cidade de Teresina-PI

Abstract

The present work carries out a study in a mill with 75hp induction electric motor used in a recycling factory for the production of garbage bags located in the city of Teresina PI. The objective of this work is to verify the dimensioning of the mill's motor power from an analytical solution. In view of this, a mathematical model was developed in order to find the necessary power for the engine in function to various parameters inherent to the machine, such as the engine speed, the transmission ratio between the engine axes and the mill rotor, the moment of inertia of the machine rotor, among others. The use of instruments was also implemented to find the variables involved in the result of the analytical solution, such as the Arduino and its modules, as well as programming software. After the acquisition of the variables, all of them were substitute in the equation resulting from the analytical solution in order to find the minimum power required by the machine. The power found for the mill was 73.6 hp. Therefore, from this result it can be attest that the use of the mathematical model presented as an analytical solution in the present work can be successful within the suggested purposes of this study and its application limited to mill models similar to that presented in this research.
