Abstract
The study investigates real-time problem diagnosis of induction motors (IMs) with digital signal processing (DSP) to improve monitoring. IMs are essential to industrial applications but can fail owing to mechanical, electrical, and thermal stressors. These defects must be detected quickly to prevent motor failure and production downtime. DSP is used to create a sophisticated real-time online condition monitoring system to diagnose three-phase IM issues. The suggested system was validated using MATLAB calculations and experimental investigations on a 415 V, 1 HP, 50 Hz, 1440 rpm, 4-pole IM. Disruptions in the stator windings, such as inter-turn short circuits or inter-phase faults, as well as problems with the rotor, such as broken bars or end rings, are identified in this investigation. Keeping an eye on negative sequence currents and analyzing fault frequencies with a fast Fourier transform (FFT). According to the results of the testing, current approaches are not very good at detecting stator inter-turn difficulties under light-load and no-load conditions. Under varying loads, the proposed DSP-based system identified stator inter-turn, inter-phase, and broken rotor bar problems. Results showed that the DSP-based online condition monitoring system was more accurate and better at detecting faults than earlier methods, making it a good fit for usage in industrial applications.
Preliminary results show that the fuzzy logic-based processor described herein can be used for accurately detecting broken bars in induction motors and can be used for accurately detecting broken bars in induction motors.

Mechanical faults in permanent magnet synchronous motor (PMSM)-driven systems can introduce disturbances and system interruptions leading to reduced performance and reliability. Effective fault diagnosis is essential for early fault detection and identification, which enables timely maintenance, reduced downtime, and efficient operation of the system. This article presents an investigation of fault signatures in online condition monitoring methods, focusing on mechanical fault diagnosis of PMSM driven systems. Angular shaft misalignment and mass unbalance faults are investigated under two different severity levels. Three axis vibration, acoustic emission, stator currents, axial and radial stray flux, and shaft torque are evaluated for fault detection, severity assessment and fault discrimination. In the first place, a theoretical framework describing the influence of the specific mechanical faults on the mechanical and electromagnetic behavior of the PMSM is established, enabling the identification of characteristic fault-related signatures. An experimental test bench is developed, integrating a PMSM with vibration, current, stray flux, acoustic emission, and torque sensors. Fault signatures are analyzed in both nominal operating condition and variable speed and load levels. Moreover, load and speed transients are investigated. Finally, to extract the most informative sensors, a data driven approach with mutual information, random forest, and Shapley additive explanations is employed. Results from this experimental investigation highlight the tradeoffs between diagnostic performance, practical implementation, and the effectiveness of combining domain knowledge with data-driven approaches for accurate, early, and cost-effective PMSM fault diagnosis.
