ANALYZING THE IMPACT OF COMPENSATING WINDING REMOVAL ON STARTING TORQUE IN UNIVERSAL MOTORS FOR PALM OIL MILLING MACHINES

This study investigates the effect of removing compensating windings on the starting torque performance of industrial palm oil milling machines using a universal machine model. Palm oil milling machines are essential in the processing of palm fruits, performing critical operations such as raw material reception, sterilization, threshing, digestion, pressing, clarification, and drying to produce refined palm oil. A key component in the reliable operation of these machines, especially under varying and heavy load conditions, is the presence of compensating windings. These windings are embedded in the field pole faces of electrical machines to counteract the armature reaction by carrying armature current, thereby minimizing magnetic field distortion.The removal of compensating windings can result in increased brush arcing and erosion, particularly in machines subjected to weak fields, high torque demands, and frequent load variations or reversals. This is of particular concern in palm oil milling, where mechanical stress and operational reliability are critical for consistent production output. Our findings suggest that uncompensated machines exhibit decreased starting torque and higher maintenance issues due to electrical noise and brush wear, leading to potential threats in production efficiency and equipment lifespan. The study emphasizes the need to maintain or improve compensation mechanisms in motor design for industrial applications in the palm oil sector
