“…The frequency, amplitude, and degree of acceleration may all fluctuate. Several different kinds of sensors are used nowadays that can be piezoelectric [135], capacitive [136], inductive, piezoresistive [137], or strain gauge [138], depending on the technique used to measure the objective. Since vibration analysis can reveal important details regarding the condition of electrical machinery, it is frequently employed in diagnostic settings.…”

Electrical machines are prone to various faults and require constant monitoring to ensure safe and dependable functioning. A potential fault in electrical machinery results in unscheduled downtime, necessitating the prompt assessment of any abnormal circumstances in rotating electrical machines. This paper provides an in-depth analysis as well as the most recent trends in the application of condition monitoring and fault detection techniques in the disciplines of electrical machinery. It first investigates the evolution of traditional monitoring techniques, followed by signal-based techniques such as spectrum, vibration, and temperature analysis, and the most recent trends in its signal processing techniques for assessing faults. Then, it investigates and details the implementation and evolution of modern approaches that employ intelligence-based techniques such as neural networks and support vector machines. All these applicable and state-of-art techniques in condition monitoring and fault diagnosis aid in predictive maintenance and identification and have the highly reliable operation of a motor drive system. Furthermore, this paper focuses on the possible transformational impact of electrical machine condition monitoring by thoroughly analyzing each of the monitoring techniques, their corresponding pros and cons, their approaches, and their applicability. It offers strong and useful insights into proactive maintenance measures, improved operating efficiency, and specific recommendations for future applications in the field of diagnostics.

An extrinsic high-temperature fiber-optic Fabry-Perot vibration sensor based on MEMS technology is described and experimentally demonstrated. The sensitive unit consists of four cross beams with a central seismic mass batch-fabricated on a silicon wafer. The sensing head is fabricated by MEMS technology including dry etching, anodic bonding and dicing processing. And the optical fiber is intergrated in the sensing head by laser fusing. According to our calculation, the sensor has a resonance frequency of 10.008kHz. Experimental results indicated that the sensitivity of the sensor from 2g to 22g, with the frequency of 200Hz, was 2.48 nm/g at 20℃ and can work stably at 400℃. The nonlinearity of the sensor was evaluated from 20℃ to 400℃ and the max nonlinear error was 1.88% at 300℃. In addition, the temperature drift and temperature crossed sensitivity of the sensor agreed well with the theoretical analysis. We believe this proposed MEMS vibration sensor has a wide engineering high-temperature application prospect.
