“…Generally, interferometric FOS for vibration enquires complex system setup and strict setup alignment, by contrast, the FBG-based sensor would be preferred for EM vibration monitoring considering fewer supporting facilities, higher spatial resolution and easier demodulation method and setup. The principle of the FBG accelerometer is converting strain variation experienced by FBG in specific time range to acceleration (Cusano et al 2004), for EM vibration monitoring, multi-axis acceleration measurements with temperature compensation are required (Morikawa et al 2002;Linessio et al 2016). Basically, temperature compensation is completed by employing another reference FBG with same temperature sensitivity at same direction to cancel out the wavelength shift led by temperature variation.…”

Accurate and efficient monitoring of electrical machine (EM) operating parameters, including temperature, mechanical vibration, torque and rotating speed and others that can indicate the EM health conditions is becoming ever more important in the world of electrical drives. The traditional methodology of one sensor per parameter can be theoretically replaced by a "one sensor measures all" technology, which can be achieved through the use of fibre-optic sensors (FOS). In this paper, several FOSs, which use different optical sensing principles for multiple physical parameter measurements of EMs, are reviewed. This paper also provides an insight into the major developments, and discusses the engineering challenges of FOS used for EM monitoring over the last few decades, and compares the advanced features of FOS with those of conventional sensors in use. Finally, a novel FOS-EM observer system scheme employing the Fibre Bragg Grating technique for multiparameter monitoring of EM health is proposed, after discussion of the preceding industrial and academic FOS cases for EM applications.

“…that can be used for this purpose. One of these signals is vibration, and is the most extensively utilized way of monitoring [2][3][4][5][6][7][8][9][10][11][12][13]. In general, a vibration signal contains a large amount of data related to the material and structure of the machinery, and with a comprehensive analysis it can reveal the degree and magnitude of the fault.…”

In the current work, magnetoelastic material ribbons are used as vibration sensors to monitor, in real time and non-destructively, the mechanical health state of rotating beam blades. The magnetoelastic material has the form of a thin ribbon and is composed of Metglas alloy 2826 MB. The study was conducted in two stages. In the first stage, an experiment was performed to test the ability of the ribbon to detect and transmit the vibration behavior of four rotating blades, while the second stage was the same as the first but with minor damages introduced to the blades. As far as the first stage is concerned, the results show that the sensor can detect and transmit with great accuracy the vibratory behavior of the rotating blades, through which important information about the mechanical health state of the blade can be extracted. Specifically, the fast Fourier transform (FFT) spectrum of the recorded signal revealed five dominant peaks in the frequency range 0–3 kHz, corresponding to the first five bending modes of the blades. The identification process was accomplished using ANSYS modal analysis, and the comparison results showed deviation values of less than 1% between ANSYS and the experimental values. In the second stage, two types of damages were introduced to the rotating blades, an edge cut and a hole. The damages were scaled in number from one blade to another, with the first blade having only one side cut while the last blade had two side cuts and two holes. The results, as was expected, show a measurable shifting on the frequency values of the bending modes, thus proving the ability of the proposed magnetoelastic sensors to detect and transmit changes of the mechanical state of rotating blades in real time.

“…FBG sensors are widely used in important fields, such as railways [4], bridges [5], the oil industry [6], and aerospace [7,8]. Up until the present day, FBG acceleration sensors have been widely used in vibration measurement, playing an important role in structural health monitoring [9][10][11][12][13]. A packaged FBG acceleration sensor is composed of a spring-mass system with one or several FBGs.…”

Mediumfrequency fiber Bragg grating (FBG) acceleration sensors are used in important applications in mechanical, aerospace and weapon equipment, and have strict requirements in terms of resonance frequency and sensitivity. A novel medium-frequency accelerometer, based on fiber Bragg grating and flexible hinges, is proposed in this paper. The differential structure doubles the sensitivity of the sensor while avoiding temperature effects. The structure model and principle for the sensor are introduced, the sensor’s sensing characteristics are theoretically analyzed, and the structure parameters for the sensor are determined through numerical analysis. The sensing experiments show that the resonance frequency of the sensor is approximately 2800 Hz, the sensitivity is 21.8 pm/g in the flat frequency range of 50–1000 Hz, and the proposed sensor has a good temperature self-compensation function and lateral anti-interference capability.
