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.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
