Pengaturan Putaran Kecepatan Motor Dc Menggunakan Sistem Loop Tertutup (Aplikasi pada Laboratorium Teknik Elektro Growth Centre)

Abstract

Motor is a device that converts electrical energy into mechanical energy. Operation of a DC motor is very easy implementation so that there are many industries that use it although it is very difficult in maintenance. The controlling of motor speed is necessary for various applications. To smooth the process in the industry, usually the motor is set by using power electronics that serves as a substitute for mechanical components. In regulating the rotation speed of DC motor consists of three methods: by setting clamp voltage (Vt), the flux (φ) and set the anchor resistance (Ra). Use of electronic circuits can be done with phase control method, control and integral cycle control with a chopper for DC motor speed control. Integral cycle control is setting the terminal voltage direct current motor using thyristor two opposite directions to control the speed. For that reason this thesis will show the results of research on setting the rotation speed of DC motor using a closed loop system. This research was conducted at the Laboratory of Electrical Engineering, Growth Centre Kopertis Region-I (Nanggroe Aceh Darussalam, North Sumatera), Medan, North Sumatra
