“…Due to the broad bandwidth provided from the laser source, reflective FOS can cover a sensing frequency range of EM high-speed rotating. Additionally, some researches have made progress on using FBG strain sensor to measure the EM rotating speed (Chang et al 2017), with derived equation which indicates that the FBG experienced strain is proportional to the square of rotating speed (Wei et al 2011). However, the performance of these FOS rotating speed sensors are still limited for high-speed EMs measurements.…”

“…Like the reasons for other mechanical EM parameters, the FBG-based FOS is the most popular technique for EM rotating speed measurement: the core mechanism is converts the strain variation to rotation speed. Such rotating speed FOS systems require some support structures except optical fibre itself for speed monitoring, for instance, rotational disc with a metal rod (Chang et al 2017), optical fibre collimators for better optical coupling (Wei et al 2011). Additionally, other principles including ring interferometric FOS with Rayleigh backscattering (Liu et al 2012), reflective FOS with codewheel (i.e.…”

“…fibre optic encoder) (Newmaster et al 2012) and Sagnac interferometric FOS (Culshaw 2006) are developed. All these fibre optic rotation sensing techniques suffer the problem of the ceiling of detectable rotating speed: The FBG and reflective FOS can detect the rotating speed no more than 5000 rpm (Chang et al 2017;Wei et al 2011) while the advanced Sagnac FOS can only recognize maximum rotating speed about 100°/h. None of them achieves the detection standard for high-speed (above 10,000 rpm) EM speed monitoring so far.…”

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.
