Optimizing Energy Efficiency in Palm Oil Factories: A Study on the Application of Three-Phase Induction Motor Rotor Cage with Autotransformator

Introduction

The three-phase induction motor is a widely used type of alternating current motor in various industries, including the palm oil industry. Its simplicity, relatively low costs, and ease of maintenance make it a popular choice in many factories. Additionally, the induction motor offers good efficiency and is able to maintain a constant rotation speed despite changes in load. However, one of the challenges faced when starting a large induction motor is a high start current that can reach 5 to 7 times the nominal current. This makes it necessary to develop a strategy to reduce the start current when starting the motor.
