Solving Motor Vibration Problems

Vibration problems in induction motors can be extremely frustrating and may lead to greatly reduced reliability. It is imperative, in all operations and manufacturing processes, that down time is avoided or minimized. If a problem does occur the source of the problem is quickly identified and corrected. With proper knowledge and diagnostic procedures, it is normally possible to quickly pinpoint the cause of the vibration. Download the Siemens white paper, "An Analytical Approach to Solving Motor Vibration Problems", to gain insight into the common sources of motor vibrations for induction motors.

This paper provides an analytical approach for expeditiously understanding and solving the possible sources of motor vibrations. This includes, but is not limited to:

Electrical Imbalance

  • Mechanical unbalance - motor, coupling or driven equipment

  • Mechanical effects - looseness, rubbing, bearings, etc.

  • External effects - base, driven equipment, misalignment, etc.

  • Resonance, critical speeds, reed critical, etc.
