PENGARUH PERUBAHAN FREKUENSI DALAM SISTEM …
research results obtained are (1) the change in frequency is directly proportional to the change in motor speed, (2) the current in the motor coil tends to be stable, (3) the motor coil tends to increase. So therefore the current tends to be stable 2.3 - 2.4 (A) to the motor coil. Keywords: Frequency Change, VFD, Motor Speed and Coil Current 1.
