摘要

本文着重分析了在线起动同步电动机在起动和再同步的动态状态下永磁体的退磁过程。考虑温度对永磁体性能和抗退磁能力的影响，采用磁场电路模型对永磁体的退磁过程进行了分析。所进行的研究结果表明，除其他事项外，从消磁风险的角度来看，电机的重新同步过程比启动本身要危险得多。

Risk of irreversible demagnetisation under transient states of the line start permanent magnet synchronous motor taking into account magnet temperature

: The paper focusses on the analysis of the demagnetisation process of permanent magnets in line-start synchronous motors in dynamic states related to start-up and resyn-chronisation. A ﬁeld-circuit model of electromagnetic phenomena was used to analyse the demagnetisation process, taking into account the inﬂuence of temperature on the properties of permanent magnets and their resistance to demagnetisation. The results of the conducted research have shown, among other things, that the process of resynchronisation of the motor is much more dangerous from the standpoint of the risk of demagnetisation than the start-up itself.

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.
