Abstract

This study presents the analysis and modeling of the optimal connection between an asynchronous three-phase electrical induction motor and a horizontal centrifuge used in olive oil extraction. The simulation, carried out using the well-established Simscape Electrical by Matlab R2024a, offers the advantage of reducing the purchasing cost of the electronic drivers and electric motors to be tested. Different connection cases among the electronic motor driver, the electric motor, and the horizontal centrifuge were examined. The findings indicate that the oversizing of the electric motor is required to increase the machine efficiency and to reduce the overall specific energy consumption; however, the asymptotic behavior of the specific energy consumption, being related to the motor power, places a limit on the motor oversizing. Indeed, raising the motor power reduces the specific energy consumption; however, this effect can be unimportant if considering the higher cost involved in purchasing both the electrical motor and the electronic motor driver. The results show that an overall percentage saving of specific energy consumption of 3.1% and 4.0% can be achieved with a slight (7.5 kW) and a medium (11 kW) oversizing of the electric motor, respectively.
