Estudo de desempenho do motor de indução trifásico, controlado por um gradador de tensão

Abstract

This work paper presents the installation and performance study of a didactic workbench speed control of a three phase induction motor controlled by a voltage gradador, having as a hydraulic load center. Also discusses concepts of semiconductors, motors and gradadores voltage for speed control of induction motors. Data collection is presented for the assembly of graphs with the main variables studied, such as: voltage x MIT shooting angle, and current MIT x firing angle. Discusses some advantages and disadvantages regarding the use of this type of stress to speed change motor controller. And as a result brings a general study on the initiative of the manufacturing and assembly of didactic workbench to facilitate understanding of the area of frequency inverters.
