EVALUASI EFISIENSI MOTOR INDUKSI PENGGERAK DRIVE PULLEY CONVEYOR EXCAVATING (CE) 42 DI PT. BUKIT ASAM (PERSERO), TBK TANJUNG ENIM

Evaluation of induction motor performance generating drive pulley Conveyor Excavating (CE) 42 at PT. Bukit Asam (Persero), Tbk. Tanjung Enim. Writer want to evaluate induction motor efficiency when it is working. The step evaluation of induction motor is calculating the output power of induction motor, input power of induction motor and efficiency of induction motor generating drive pulley Conveyor Excavating (CE) 42 at PT. Bukit Asam (Persero), Tbk. Tanjung Enim. The data inside this Final Report had been collected by interview with the Electrical Maintenance employees of PT. Bukit Asam (Persero), Tbk., the Mechanical Maintenance employees of PT. Bukit Asam (Persero), Tbk. and observation on the writen object direcly. Base on the data and the result of calculation, the value of output power is affected by the value of conveyor capacity. While the value of input power is affected by the value of voltage, current and cos θ that motor. And average value of induction motor efficiency is 58,67%. Writer conclude that induction motor efficiency generating drive pulley Conveyor Excavating (CE) 42 at PT. Bukit Asam (Persero), Tbk. Tanjung Enim is under IEC standard
