摘要
随着低碳经济在交通领域的延伸,电动汽车及其相关技术得到了快速发展,作为电动汽车的动力源,电机及其驱动系统的可靠运行是保证整车安全稳定运行的关键因素。永磁同步电机(PMSM)由于众所周知的技术优势在该领域得到了广泛关注,而其控制性能、工作效率及运行可靠性在很大程度上取决于转子永磁体的健康状况,因此,永磁体质量实时可靠监控就显得尤为重要。本文通过对该领域既有研究成果的梳理,分析了PMSM退磁故障的产生机理,对既有故障诊断技术进行对比和总结,提出永磁体退磁故障诊断关键技术的发展方向和解决思路,旨在开辟电动汽车安全可靠运行的新途径。
With the tow-carbon economy＇s extension to the transportation feld, electric vehicles （EV） and its relevant technology gets rapid development, as the power source of EV, the reliable operation of the motor and its drive system is the key factor to ensure safe and stable operation of EV. Now, permanent magnet synchronous motors （PMSM） is becoming the preferred choice in this field due to their well known advantages, and the permanent magnet rotor is one of the most critical components of PMSM, which determines its performance, efficiency and drive system＇s reliabitity, and tt^erefore, it is very importance to monitor the quality of permanent magnet in real time. For this purpose, through organizing the existing literatures and reviewing the previous research results, the demagnetization fault mechanism is first analyzed, and some comparison and summarization on existing fault diagnostic technology are made, and then the development trends and some solutions of key technology are put forward for demagnetization fault diagnosis. Abovementioned work aims to open up a new way for safe and reliable operation of EV.
