This paper presents the design and implementation of a smart wireless motor control system using Wi-Fi technology for real-time remote operation of induction motors. The proposed system integrates a NodeMCU ESP8266 microcontroller, a VFD-based motor driver, a voltage conversion interface, and a mobile application for user-level control. Traditional wired control systems often suffer from installation complexity, limited flexibility, and restricted scalability. To overcome these limitations, the system utilizes Wi-Fi communication to achieve seamless long-distance control and monitoring. A closed-loop feedback mechanism enables real-time Rotation Per Minute (RPM) of the motor shaft regulation and acquisition. The control algorithm processes user commands such as start, stop, forward, reverse, and speed regulation with minimal latency. A voltage regulator ensures proper signal compatibility between the NodeMCU and the VFD reference input. The prototype was constructed and tested under variable load and distance conditions. Experimental results demonstrate high response accuracy, stable wireless communication, and reliable performance. The system reduces wiring requirements and enhances user convenience in industrial and domestic applications. The mobile app interface provides intuitive, user-friendly interaction. The findings validate the feasibility of Wi-Fi-based smart motor control systems for modern automation. The work highlights a cost-effective approach toward future IoT-enabled motor control solutions.
