How can you damp the vibrations of BLDC motor?

Question

anonymous · Answer

Vibration isolation is a hard task to accomplish especially for a wide range of motor speeds. If you are running the motor at a constant speed, we can can place the motor on a tuned table. The table should consist of a spring system that has the same frequency response as the motor. Obviously, the motor will exhibit several harmonics of vibrational frequencies. We should tune the table to isolate the harmonic with the greatest amplitude. 
Grab a book covering dynamics and vibrations to better understand the governing EOM dealing with 1DOF vibrations.

can u suggst a gud book ?

The book I used in both of my dynamics classes were terrible, so I would hate to recommend those. Do a google search for "engineering dynamics and vibrations" or "vibrations" or "dynamics and vibrations". These should produce some good results. If you have access to a library, I would recommend browsing their selection.
