Abstract

Abstract This article reports a distributed thermal monitoring approach for permanent magnet synchronous motors (PMSMs). The detecting system is based on using an electrically non-conductive and electromagnetic interference-free fiber Bragg grating (FBG) temperature sensor embedded in the stator of PMSMs. FBG thermal sensors with different annealing temperature were fabricated and integrated with a motor stator, and their accuracy for temperature measurement was evaluated. According to the experimental results, the error within 200 °C is limited between −6 °C and 2 °C when the annealing temperature is 95 °C, and the error decreases to ±1 °C when the annealing temperature is 120 °C, indicating that performance of FBG thermal sensor is improved by increasing the annealing temperature. This article provides methodogical guidance for improving the accuracy of stator temperature distribution measurements based on the FBG thermal sensor.

具有光纤布拉格光栅（FBG）的聚合物永磁同步电机的温度分布特性

摘要本文报道了一种永磁同步电动机（PMSM）的分布式热监测方法。该检测系统是基于使用嵌入PMSM定子中的不导电且无电磁干扰的光纤布拉格光栅（FBG）温度传感器。制作了不同退火温度的FBG热传感器，并将其与电机定子集成，对其温度测量精度进行了评估。根据实验结果，误差在200以内 °C限制在−6之间 °C和2 退火温度为95℃时 °C，误差降至±1 退火温度为120℃时 °C，表明提高退火温度可以提高FBG热传感器的性能。本文为提高基于FBG热传感器的定子温度分布测量精度提供了方法指导。

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
