Steps to test the Motor Vibration using wireless vibration sensor

[Voicecoil]

I've no idea how you'd do it with that sensor, but normally my approach for vibration analysis is to sweep the stimulus frequency (i.e. motor speed in this case) and record the sensor output vs stimulus frequency so you can identify problem frequencies: these can then be investigated further by running a FFT of the sensor output. If there's no easy way to sweep the stimulus, just run some FFT's at a number of different running conditions and look for frequencies that crop up repeatedly ....... then you have to work out what's causing them and how to fix them!
