Analysis of the Use of Electric Energy in a Single Phase Induction Motor to Drive a Bio-Pellet Machine from Empty Palm Bunch

This research focuses on regulating the speed of a single-phase induction motor in making biopellets from empty palm oil bunches. Bio-pellets are a renewable energy fuel source. Power consumption in induction motors at constant speed is greater and this can cause waste of electrical energy. To overcome this problem, we need a way to save electrical energy, especially in operating electric motors. One effort to save electrical energy when operating an induction motor is to use an inverter. From the research results, it is known that the power of an induction motor operated without using an inverter is 0.610 kW with electrical energy of 0.603 kWh and using an inverter is 0.376 kW with electrical energy of 0.396 kWh. The electrical energy use of a single phase induction motor using an inverter is 0.207 kWh lower than without an inverter with electrical energy savings of 34.32% or Rp. 8,395.92 in one month.
