Abstract

Perkembangan industri pelayaran selalu mengarah kepada penekanan biaya operasi dengan tidak menambah polusi. Propulsi diesel atau disebut juga propulsi konvensional adalah yang paling efisien sekaligus penyumbang polusi maritime terbesar sampai saat ini. Propulsi elektrik memanfaatkan motor listrik sebagai penggerak utama. Terdapat dua jenis motor listrik yang memungkinkan digunakan dalam sistem propulsi elektrik, yakni; motor DC dan motor induksi tiga fasa. Mengacu pada kemungkinan tersebut, studi ini akan membahas mengenai karakteristik antara voltase terminal dan torsi, juga arus medan dan torsi. Dihasilkan bahwa torsi yang diproduksi oleh motor DC berbanding lurus dengan kecepatan motor (RPM). Peningkatan kecepatan motor akan mempengaruhi besar torsi. Voltase masuk dan terminal sebagai pengatur variabel-variabel hasil dalam pengoperasian motor. Dalam kasus ini, voltase medan yang divariasikan memberikan hasil berupa grafik operasi motor. Dengan voltase medan 50 volts, jangkauan grafik operasi motor maksimum terletak pada 150% kecepatan dan 160% daya. Sementara, dengan voltase medan 60 volts dihasilkan jangkauan grafik operasi yang lebih luas dibandingkan dengan voltase medan 50 volts. ========================================================= The development of shipping industry always searches through the most benefits system for reducing costs of propulsion system without create more pollution. Diesel propulsion system or also known as conventional propulsion system is efficient but requires high operating costs and create high level of marine pollution. Electrical propulsion system is using electric motors as the prime mover of the propeller. There are 2 types of electric motors that will be used for research of electric propulsion system, there are; DC motors and three-phase induction motor. As the use of DC motor as a prime mover for this electrical propulsion system, this study determines the characteristic between voltage terminal with torque and also field current with torque. It results that torque produced by the DC motor is in the same magnitude with the speed (RPM). The higher the speed have shaped the value of the torque. The input and terminal voltages adjusts all variables and results. In this study, different field voltage creates different pattern of motor envelope. Its manner to propeller curve occurs total different results. With field voltage of 50 volts, the ranges of motor envelope immoveable in the point of 150% of present speed and 160% power. While field voltage of 60 volts serves larger ranges of motor envelope which possible to reach further than 50 volts curve
