Estudo em vazio sobre motores CC com ímã permanente com aplicação na indústria automotiva

Abstract

This paper aims to address a study on DC motors with permanent magnets that are used in the automotive industry, specifically for ventilation and heat balance applications. This study is divided into three stages: The first addresses the constructive aspects of these engines with emphasis on magnetic materials and permanent magnets, highlighting their characteristics and properties as well as their applications in rotating electrical machines.The second part of this work is a practical study of these specific application equipment, focusing on preparing an electrical characterization and also raise some mechanical parameters that assist in working out the final stage of work. Finally, to finish, a simulation is performed in Matlab programming environment using the electrical and mechanical parameters determined in order to assess the accuracy of these parameters.
