Vibration Analysis

Vibration Analysis is performed by our technicians using the latest technology to accurately diagnose drives and motors while in service without interruption. Trends can also be tracked and monitored to predict potential trouble spots.

What is Vibration?

In a dictionary, you might see vibration defined as “to swing back and forth; to oscillate.” But in the electric motor industry, it means the pulsating motion of a motor or part of the motor from its original place of rest. Vibration is identified by the following components:

  • Frequency – Used to determine how often a vibration is occurring
  • Amplitude – Used to determine the severity/magnitude of a vibration
  • Phase – Used to determine the relationship between two signals of the same frequency, measured in degrees

Why use Vibration Analysis?

Vibration analysis plays a crucial role in electric motor maintenance. While some degree of vibration is expected in rotating machines, excessive vibration can lead to severe damage. By the time, noise is heard coming from equipment, it is probable that some damage has already occurred beyond the need for lubrication.  Our accredited ISO Cat 1 technicians are equipped with the most state-of-the-art analyzers and sensors to capture data which will provide them with insight into what components are responsible for which signals, and which faults are present. The data is then interpreted and detailed into a report which is given to the customer thus becoming part of their predictive maintenance routine. Here at Dreisilker Electric Motors we recommend performing monthly to quarterly vibration analysis so the collection of data can be compared to previous readings. It is very important to do this so we can diagnose mechanical faults and track the severity from slight to extreme over time. These data driven decisions can help you get the most value from your electric motors.
