Abstract

Motor Induksi mempunyai banyak keunggulan di segi teknis maupun ekonomis, karena itu motor induksi terutama jenis motor induksi 3 fasa banyak digunakan pada dunia industri. Akan tetapi motor induksi juga mempunyai kekurangan, antara lain arus awal (start) yang besar yang dapat mengakibatkan penurunan tegangan sistem dan mengganggu kerja sistem peralatan lain dalam satu saluran. Maka dari itu diperlukan metode Soft Starting untuk mengurangi lonjakan arus pada arus awal (start) yang besar. Metode Soft Starting dilakukan dengan menggunakan komponen elektronika daya yaitu triac. Tegangan masukan motor induksi diatur dengan memberikan sinyal tunda pada triac dengan waktu tertentu yang diatur oleh platform Arduino. Pada beban motor induksi 3 fasa, besar arus starting relatif terkendali dan lebih kecil jika dibandingkan dengan metode DOL dan Wye-Delta. Hasil dari perancangan Modul Starting Motor Induksi 3 Fasa dengan metode Soft Starting mempunyai pemilihan waktu soft start antara 4 detik hingga 25 detik, sehingga dalam rentang waktu tersebut tegangan input yang masuk bertahap mulai 1% hingga 100% dari tegangan 380v Delta. ================================================================================ Induction motor has many advantages in terms of technical and economical, therefore induction motors, especially types of 3-phase induction motors are widely used in the industrial world. However, induction motor also has disadvantages, such as the starting of large currents (start) which may lead to voltage drop system and interfere with the work of other equipment systems in the same line. Therefore, Soft Starting method is needed to reduce the current spikes on the starting motor induction. Soft Starting method is done by using power electronics component that is triac. The input voltage of the induction motor is regulated by providing a delay signal on the triac with a specified time set by the Arduino platform. At the 3 phase induction motor load, the starting current is relatively controllable and smaller then the DOL and Wye-Delta methods. The result of the design 3 Phase Induction Motor Starting Module with Soft Starting method has soft start time selection between 4 second until 25 second, so in that time period input voltage entering gradually from 1% to 100% from 380v Delta voltage
