This paper proposes a novel real-time diagnostic methodology based on envelope analysis of the square root of three-phase current signals, specifically designed to identify rotor bar faults under varying load conditions. The proposed system utilizes a Field-Programmable Gate Array (FPGA) for high-speed current signal acquisition and transmits data via the UDP protocol for real-time processing. A custom-developed graphical user interface, implemented in C# using Visual Studio, enables intuitive real-time monitoring and visualization of motor health. Experimental validation highlights the accuracy and robustness of the proposed approach in detecting rotor bar breakage, underscoring its suitability for industrial applications requiring reliable and timely fault detection.
