Phase Analysis: Making Vibration Analysis Easier

Phase Analysis: Making Vibration Analysis Easier

2) Cause and Effect Vibration: For every action, there is a reaction. Some of the vibration we measure is the effect of other problems. For example, the force caused by rotor unbalance can make the machine look like it is out of alignment, loose or rubbing. Consider all of the things that shake and rattle on your car when one tire goes out of ...

A Closer Look At Air Gap Eccentricity

A Closer Look At Air Gap Eccentricity

•An air gap eccentricity results in increased levels of vibration due to the uneven magnetic pull it creates between the circumference of the rotor and stator bore. Over time, these elevated levels of vibration can result in excessive movement of the stator winding, which could lead to increased friction and eventually a turn-to-turn, coil-to ...

How Vibration Sensors Work ?

How Vibration Sensors Work ?

Sensors used to measure vibration come in three basic types: displacement, velocity, and acceleration.. Displacement sensors measure changes in distance between a machine’s rotating element and its stationary housing (frame). Displacement sensors come in the form of a probe that threads into a hole drilled and tapped in the machine’s frame, just above the surface of a rotating shaft.
