Abstract :
This article reviews the physics that cause vibration in three-phase motors and suggest methods to reduce vibration. There are two major causes of vibration in IEEE 841 motor. Unbalance vibration at IX rotational speed, vibration due to magnetic forces. Vibration in an installed motor system can be caused by numerous variables. This vibration is the result of rotor and stator forces on the bearings acting with in the system. Final attempt are made to quantify the cost of motor vibration in terms of equipment life.
