Design and construction of a 3-phase motor control system with an inverter in conjunction with A programmable controller Logic can be remotely commanded through the Internet of Things system and touch screen

Abstract

The objectives of this research were to: 1) find out the efficiency of a 3-phase motor control system with an inverter, in conjunction with a remote controlled programmable logic controller through the Internet of Things and touch screen system; 2) create an innovative media for learning management in the course on control systems in industry, code 301 04-20 06, on network systems; and 3) to verify the user’s satisfaction of using a 3-phase motor control system. The research was designed to place the equipment in the front of and inside the control cabinet, using a computer design program. A program was written to control the Programmable Logic Controller with the MELSOFT Series GX Work 2 program, control the touch screen with the Sktool program, and connect the Smart Life application to the Smart Switch board for remote control via a mobile phone. The inverter size used in the test was 0.1 kW, and the motor used was 0.20 kW. The results showed that there was not much difference in load current and voltage for both forward and rotational reversal frequencies at 10 Hz, 25 Hz, 30 Hz, and 35 Hz. The system could be operated according to the conditions via smart Life application, touch green, and mobile phone. The overload range of the inverter was at a frequency of 35 Hz and above. The overall satisfaction was good with an average of 𝑥̅= 4.20
