Development of a Three-Phase AC Motor Based Drive System to Increase Production Capacity in Small Industrial Communities

Abstract

This study addresses the operational challenges of achieving precise positional control in three-phase AC motors, particularly in small industrial communities aiming to enhance productivity through advanced motor systems. Despite their efficiency, three-phase AC motors (0.25–1 kW) often struggle with control precision due to inherent inertia and extended start-stop cycles. Typically, these motors require 1–2 seconds to reach nominal speed and 2–3 seconds to stop, disrupting operations demanding high precision and responsiveness. To overcome these limitations, this research proposes a novel control mechanism capable of reducing start-up time to 0.5 seconds and stopping time to 0.75 seconds. The system ensures accurate positional halts, critical for applications like automated production lines and specialized equipment, such as missile launchers. The control process is optimized for seamless synchronization with other subsystems, mitigating disruptions from delayed motor responses. Adapted for small industrial contexts, the proposed solution addresses practical challenges by reducing downtime and enhancing accuracy in short-duration tasks. For instance, the system excels in rapid object tracking and locking scenarios, where delays could compromise target acquisition. By integrating this advanced motor control system into local industries, the research fosters community empowerment through increased production efficiency, reduced operational delays, and technological self-reliance. This innovative approach demonstrates the potential of modern motor control technology as a catalyst for industrial and economic development, particularly in underserved regions where traditional systems fall short.
