MOTOR: Journal of Automotive Engineering

This study aims to design and test a simulator of the alternating current generator starter system using a step-up dc to dc converter and a brushless direct current controller as an instructional medium. The simulator is developed to help learners understand the working principle of the alternating current generator starter system, which integrates the functions of both a starter and an alternator into a single unit. The research method employed is a technical and experimental approach, which includes needs analysis, component selection, assembly, and both electrical and mechanical testing. Testing was carried out to ensure the functionality of each part, such as increasing the voltage from 12V to 36V and regulating current through the brushless direct current controller to rotate the rotor. The results indicate that the simulator accurately replicates the operational characteristics of the alternating current generator starter system, including the relationships between voltage, current, rotor speed, and back electromotive force. Electrical stability and the simulator frame ensure the simulation runs smoothly without mechanical disruption, making it appropriate for educational and technical training purposes and offering potential for further development. Penelitian ini bertujuan untuk merancang dan menguji simulator sistem starter alternating current generator menggunakan step-up dc to dc converter dan controller brushless direct current sebagai media pembelajaran.
