Study on fault monitoring and diagnosis of motor vibration of new energy motor
新能源汽车电机振动的故障监测与诊断研究

摘要

受转子不平衡、转子对中不良、机械出现松动、滚动轴承故障等因素影响，导致新能源汽车电机振动故障出现，不仅影响到新能源汽车电机正常使用性能的发挥，还会对新能源汽车可持续发展构成极大的威胁，加强新能源汽车电机振动故障监测与诊断研究就显得十分有必要。本文联系新能源汽车驱动电机的主要类型，对引发新能源汽车电机振动故障的原因进行细致分析，并尝试从诊断电池是否正常工作、重点关注电池兼容性能、及时开展电机测试工作、完善整车控制技术等方面入手，提出几点有效故障监测和诊断手段，以供参考。

Abstract

by the rotor imbalance, rotor to bad, mechanical loose factors, rolling bearing failure, leading to new energy vehicle motor vibration failure, not only affect the normal performance of new energy vehicle motor, but also pose a great threat to the sustainable development of new energy vehicles, strengthen the new energy vehicle motor vibration fault monitoring and diagnosis research is very necessary. This paper contact the main types of new energy vehicles drive motor, the cause of new energy vehicle motor vibration fault detailed analysis, and try to diagnose the battery works normally, focus on battery compatibility, timely motor test work, improve the vehicle control technology, etc, put forward some effective fault monitoring and diagnosis means, for reference.
