Diseño e implementación de un tablero de control para el rotor kit del laboratorio de diagnóstico técnico y eficiencia energética de la Facultad de Mecánica de la ESPOCH

Abstract

This curricular integration work was presented with the objective of designing and implementing a didactic control board to monitor the speed of a three-phase induction motor, using a frequency inverter and, with the implementation of a development board of Arduino UNO type, a programming was carried out so that it is able to transmit data of frequency of entrance of the alternating current motor to be able to observe them in the LCD screen placed in the face of the board. The INVT frequency inverter was in charge of carrying out the speed variation in the motor and the monitoring was carried out by means of its button on the screen where, at the end, it was possible to check the revolutions per minute, current and voltage. Several tests were carried out on the board so that the electrical connection is in accordance with the control and power diagram established by checking the continuity with the multimeter. For the analysis of results, speed control was achieved, which is displayed on the drive screen and in turn regulated by a precision potentiometer. Encapsulated relays were used to change the direction of rotation of the motor to create a system that changes the direction of rotation of the motor. Finally, infrared thermography measurements were carried out on the electrical panel, to observe hot spots in the electrical connections, in order to carry out these tests. It was concluded that the control panel works in optimal conditions to be used in the different practices of laboratory. It is recommended that you work in conjunction with the operation manual to avoid mishandling of the control panels and to have a correct handling of them.
