论文摘要
如今,由于环境问题和现代社会的充满活力的依赖性,对汽车应用的兴趣特别是混合动力汽车(HEV)的兴趣。因此,有必要在这些车辆故障诊断系统中研究和实施,这使它们更可靠,更安全地增强其可持续性。由于其在汽车系统的可用性中的影响,几项研究工作集中在电机的故障诊断方法上。我们的工作符合这种情况,首先是对永久磁铁同步电机(PMSM)的故障和诊断方法的综述,其次是使用基于有限元方法和信号处理(FEMM-MATLAB耦合)的分析数字方法来检测和分析表面上的demagnetization bultssmsmsmsmsmsmsmsmsm。因此,这项工作主要包括故障性能,谐波组件和信号频谱特征,时间频率分析技术。将获得的结果与健康操作下的运动特性进行了比较,以与断层有不同的检测。
Today, interest in automotive applications notably Hybrid Electric Vehicles (HEV) has risen due to environmental concerns and the modern society's energetic dependence. Consequently, it is necessary to study and implement in these vehicle fault diagnosis systems which allow them to be more reliable and safe enhancing its sustainability. Several research works have been focused on Fault Diagnosis approaches for electric machines due to it's influence in the automotive system availability. Our work fits into this context, firstly with a review of faults and diagnosis methods of the permanent magnet synchronous motor (PMSM) and secondly by using analytical-numerical approach based on finite element method and signal processing (FEMM-MATLAB coupling) in order to detect and analysis of eccentricity and partial demagnetization faults for surface mounted PMSM. So, this work mainly includes fault performance, harmonic component and signal spectrum characteristics, timefrequency analysis technique. The outcomes obtained are further compared with the motor characteristics under healthy operation to have distinct detection to faults.
