Bancada de acionamento e controle de velocidade para máquina de indução trifásica a partir de um microcontrolador

Abstract

With the technological advancements and industrial innovations of the 20th century, much of the mechanical work began to be performed by electric machines, primarily induction motors, due to their practicality and robustness. As a result, the control of these machines became a fundamental component in the application of this technology, given the wide range of applications that require specific behaviors from these motors. In this context, the project to be developed involves the practical application of a drive and control bench for a squirrel-cage three-phase induction motor. The bench will consist of the induction motor, a frequency inverter, encoder, signal conditioning circuits, DC power supply, and microcontroller. The implementation of this project covers theoretical aspects related to the induction machine, microcontrollers, power electronics, drive circuits, and sensing systems. Experimental results aim to demonstrate the operation of the bench, enabling future use for analysis and control of three-phase electric machines in the laboratory. Ultimately, the work aims to contribute to the educational environment and the understanding of concepts taught in various disciplines of the Electrical Engineering course at the Federal University of São Carlos
