Unbalance and runout are two terms that we hear frequently in the predictive maintenance community. Both unbalance and runout can be serious issues and need to be addressed to prevent inefficient functioning and damage to machines. Unbalance occurs due to corrosion, erosion of the fan wheel, or if a correction weight is removed. Runout occurs […]

Electric motors are almost always well-balanced when they leave the motor manufacturer.  But occasionally, motor unbalance problems are picked up with vibration monitoring tools, such as the OneProd Hawk. Here are some easy troubleshooting methods to determine the cause of unbalance in the motor. An electric motor’s rotor, like any rotating mass, cannot become out […]

Unbalance is another common machinery vibration problem.  Unbalance is the uneven distribution of mass around a rotating axis. Any rotating machine can have an unbalance problem, not just fans.  It is important to note that once rotating machinery components are balanced, they should stay balanced until something changes.  These changes are normally: Dirt, paint, or […]
