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.
