Three-phase induction motors are widely used as electric drives in industrial sectors; therefore, their reliability and operational condition must be continuously maintained. One common repair method applied to induction motors experiencing winding damage is the rewinding process. This study presents an evaluation of the rewinding results of a three-phase induction motor rated at 1.5 kW with a nominal speed of 3000 rpm, conducted at the Electrical and Instrumentation Workshop Unit of PT. Semen Padang. The objective of this research is to assess the operational feasibility of the motor after rewinding by examining the conformity of electrical parameters, the quality of the insulation system, and the phase current balance. The research methodology includes collecting nameplate data as a reference, documenting stator windings, performing a visual evaluation of the stator condition, and conducting electrical tests comprising winding resistance measurement, insulation resistance (Rsi) testing, Polarization Index (PI) evaluation, and no-load current measurement. The test results indicate that the winding resistance values are balanced at 4.6 Ω for each phase, while the insulation resistance ranges from 1.80 to 3.31 GΩ with a Polarization Index value of 2.17. The no-load current test results show an average current of 1.29 A, corresponding to approximately 41% of the rated current specified on the nameplate, with a current unbalance of 2.3%. Based on these results, it can be concluded that the rewinding process was successfully performed and the induction motor meets the technical requirements and is suitable for re-operation.
