Using noise and vibration analysis system, the transmission system noise and vibration of a traction motor were tested, and the characteristics of the noise and vibration were analyzed. It is concluded that the noise level increases with the rotation speed increasing mainly in the frequency range near 800 Hz, and noise of MIC02 is higher than the noise of MIC01; gearbox vibration is bigger than motor vibration. This work provides a reference for noise and vibration reduction design of transmission systems of traction motors.
