Diseño e implementación de un arrancador electrónico para el motor DC Baldor CDP3440 para realizar prácticas en el Laboratorio de Máquinas Eléctricas, FIE.

Abstract

Starters and controls have been designed to meet the needs of the many kinds ofengines, they are needed to limit the flow of armature that fows when the engine is connected, the proposed designis very useful to perform practices in the laboratory of electrical machines of the school of Electronic Engineering in Control and Industrial networks In the electronic starter a single phase semi controlled was used in order to obtain direct voltage from a voltage altemate, controlled rectifiers of silicon (SCR) of power were built with diodes and thyristors.The objectives are: 1.To provide simplicity and versatility of mounting.2 To ensure a perfect motor drive By using the inductive and deductive method, was conducted hypothesis and experiment, based on the modification that suffers the form of an alternative voltage sane wave when it passes by a semiconductor (thyristor), various electronic circuits of controland power were analyzed, which came together to implement the electronic starter.By changing the angle of the shot are obtained voltage values of continuous flow controlled in the output of the rectifier, for an angle of 150 degrees is obtained a tension with value of 7.23 volts which is supplied to the engine, in this way provides It isconcluded that to vary the speed of a direct current, the supply voltage must be controlled, which is achieved with the semi controlled rectifier It is recommended to use the clectronic starter for academic purposes since its design allows knowing the different stages of the speed control.
