This Research explores the design and development of a Human-Machine Interface (HMI)-enabled Variable Frequency Drive (VFD) system for efficient speed control of single-phase induction motors. The primary objective is to provide an intuitive and user-friendly interface for real-time monitoring and control of motor speed using a touchscreen display. The proposed system integrates the fundamental components of a VFD—namely, the rectifier and inverter. The rectifier section is responsible for converting the alternating current (AC) input into direct current (DC), which is then modulated by the inverter to produce an AC output at variable frequency and voltage, tailored to the motor’s operational requirements. The incorporation of HMI technology simplifies interaction with the motor control system, allowing users to input desired speed values and receive immediate feedback on system performance. This approach enhances the precision and flexibility of motor operation while also contributing to energy efficiency and system reliability. By varying the frequency and voltage supplied to the motor, the VFD facilitates optimal performance under different load conditions, reducing mechanical stress and extending equipment lifespan. This research not only demonstrates the theoretical principles behind VFD technology but also showcases its practical implementation through hardware and software integration. The developed system provides a cost-effective and scalable solution for various industrial and domestic applications where precise motor control is essential. Overall, the HMI-based VFD design offers a modern, efficient, and accessible approach to induction motor speed control, contributing to smarter automation in electrical drive systems.
