PLC KONTROLLÜ ASENKRON MOTORLARA REAKTANS BOBİNİ İLE YOL VERME

Abstract

Programmable logic controllers (PLCs) are electronic systems that designed to operate in industrial facilities and operate according to digital principles. These devices are designed to control a system with its own analog or digital input / output modules, functions such as logical control, timing and counting. In addition, PLCs can be used to collect data depending on various processes in production. These data are measurable data such as temperature, ambient temperature, humidity and the like. In this study, starting condition of three phase asynchronous motor controlled by PLC is investigated. Asynchronous motors draw about 3 to 7 times their rated current during the starting time. This current value is harmful to the network. Thus, this current value is reduced by connecting the reactance coil to the stator of the induction motors. The most commonly used motor type in the industry are asynchronous motors. The fact that it has a simple structure that works with alternating current and also requires low maintenance has made them more preferred in the industry than other motor types. PLCs are devices that can control the execution of the work in a specific order. For example; It can be used in the systems where the floors will be controlled in which order the elevators will be in which order. PLCs are long lasting and reliable. They can work safely in dusty, dirty, humid, electrically noisy environments. PLCs are very small and space-saving devices according to their capabilities. This allows the PLCs to be installed in any environment without any problems. In addition to logic-based operations, PLCs also include commands for performing mathematical operations. These features are one of the reasons that make PLCs superior.
