Abstract


Jurnal ini menyajikan desain rinci dan implementasi teknik pengaturan akselerasi pada motor BLDC untuk soft starting dengan redaman arus. Pada umumnya, arus sangat tinggi saat motor melakukan akselerasi terlebih lagi pada kondisi pengawalan (starting). Hal ini dapat menyebabkan penggunaan energi menjadi tidak efisien. Pada penelitian diusulkan sebuah desain pengaturan akselerasi motor BLDC dengan metode six-step PWM yang akan mengendalikan inverter tiga fasa. Sensor hall effect digunakan sebagai sinyal masukan untuk mikrokontroler dan digunakan untuk mengatur sinyal luaran PWM untuk proses swtching/pensaklaran pada mosfet. Pada penelitian ini digunakan mikrokontroler STM32F407. Pengujian telah dilakukan dengan dua kondisi yaitu tanpa pembatasan arus dan dengan pembatasan arus dengan set point 250 rpm. Hasil menunjukkan pada kondisi tanpa pembatasan arus, waktu akselerasi cukup cepat dengan arus starting 44A, sedangkan ketika pada kondisi dengan pembatasan arus sebesar 22A, waktu akselerasi lebih lambat 2 detik namun rata-rata arus starting 22A.
