Vibration measurement of motor

Further reductions of noise and vibration, which provide uncomfortable feeling to the people on board, are required for HEV/EV motors. It is necessary to analyze what kind of vibration has been generated from the motors. The followings are key considerations for measuring vibration or noise from motors.

1. Electromagnetic force as excitation vibration
2. Motor structure of transfer system
3. Vibration transmission to equipments

The LV-1800 laser Doppler Vibrometer can measure vibration of the object with a high S/N ratio and enables high accurate vibration measurement/analysis.
