Implementación de un módulo de sincronización y secuencia de arranque de dos motores trifásicos jaula de ardilla comandado por relés programables y variadores de frecuencia.

Abstract

A synchronization module and starting sequence of two three-phase squirrel-cage motors commanded by a programmable relay and frequency variators were implemented, for which the synchronization and sequence of motors, frequency inverters, programmable relays, was investigated. and the software that will allow us to make the communication between the programmable relay and a computer. Once the devices to be used in the module were assembled, the connection was made between the programmable relay and the devices that will send a signal to it and the one that will receive them. Finally, each of the devices was programmed to work according to the scope of the implanted module. The module is designed so that two squirrel-cage motors are synchronized, starting at an ignition speed and for a connection time of the second motor programmed with the software. The interconnection between the devices and the transmission of data and signals between the computer and the programmable relay was successfully configured, and the corresponding tests were performed with each programming made in the software. We can conclude that the synchronization of the speeds of the motors and the sequential start was successfully achieved thanks to an adequate selection and programming of the electronic control devices that make up the module. It is recommended that, in order to manipulate the devices, they must first familiarize themselves with their technical manuals, which are publicly available and can be found digitally.
