Asutan Motor Searah dengan Tahanan Bertingkat (Direct Current Starting Motor With Grading Resistance)

摘要

The electrical system must has as low aspossible resistance to get high efjisien. One .of that is starting system. In this system, lowest resistance reach when it only use armature resistance. But lower resistance make higher current. In other hand, highest current should not higher than insulation system could take. So this study trying tofind to get safety on the starting system.
