EFISIENSI MOTOR INDUKSI GBM-301 150 KW SEBAGAI FAN FOR DRYER DI PUSRI IV PALEMBANG

The electric motor have an important role in industries because it is one of the equipment that change the electric power into mechanical power as driver for various need, including a three phase induction motor that used as a blower's driver (fan for dryer) UGB-301 in PUSRI IV for sending the urea powder to the Prilling Tower. The writer wanted to know how the efficiency of the motor GBM-301. The power calculation performed to calculate the motor’s efficiency, so we can know the driver can be reused or should be replace immediately. Beside the calculation of Pin, we need to know the Pout. Based on motor's name plate, the input and output power are 158 KW and 149 KW, so that the total of power losses is 9 KW with the efficiency 94,5%. While based on the measurement, the motor's input and output power are 156 KW and 140 KW. The total of power losses is 16 KW and the efficiency value is 89,7% So it concluded that the induction motor GBM-301 as the blower's driver in PUSRI IV is still able to used and should not to be replaced with a new motor considering that the motor's efficiency value is still fairly high
