The rewinding method used in this research is copy method. Namely doing rewinding with the number and arrangement of the same coil from the factory default. Through this method is expected that the power and efficiencyofthemotorwillbethesameasthefactorydefault.Theresults of the test show that motor efficiency can reach a value above 85% after repair by rewindingmanually.Teknik ElektroElektronikaEngineering and Allied Operations (Teknik dan Ilmu yang Berkaitan)Economics (Ilmu Ekonomi)Mechanization and Automation of Factory Operation/Mekanisasi dan Otomatisasi PabrikThesis
