Here is a question for the variable speed drive experts
Why will a drive using proportional Volts/frequency control cause or amplify vibrations in the rotated equipment when the same drive using sensorless vector control does not?
I have witnessed a situation where the rotated equipment was vibrating noisily at certain motor frequencies but when the drive was changed to sensorless vector control, the vibration became unnoticeable.
