The work presents experimental analysis of acoustic and vibration response of EC motors in
which there was a desire to increase the speed. Electric motors are used in many devices,
where increased vibrations and noise can adversely affect their operation. Vibrations causes
wear and reduce product lifetime while noise negatively affects human well-being and
health. Vibration and noise were measured on EC motors, and based on the obtained
measurements, an analysis was performed to verify the causes of such vibration and acoustic
response.
