Disclosed are a method and device for diagnosing the dynamic eccentricity of an electric vehicle drive motor. In the present embodiment, according to the method and device for diagnosing the dynamic eccentricity of an electric vehicle drive motor, in a no-load environment where the electric vehicle is raised from the ground due to a lift, the dynamic eccentricity of the motor of the electric vehicle can be accurately diagnosed based on the leakage magnetic flux signal generated when the motor is driven rather than the vibration-based diagnosis of the motor without outdoor driving.

    전기차 구동 모터의 동적 편심 진단 방법 및 장치를 개시한다. 본 실시예는 리프트로 인해 전기차가 지면으로부터 상승한 무부하 환경에서 실외 주행없이 모터의 진동 기반 진단이 아닌 모터 구동시 발생되는 누설 자속 신호를 기반으로 전기차의 모터의 동적 편심을 정확하게 진단할 수 있도록 하는 전기차 구동 모터의 동적 편심 진단 방법 및 장치를 제공한다.
