Rotor Runout Measurement

Prosig’s DATS Software includes an optional add-on package for rotor runout measurement. Runout may consist of two components – Mechanical Runout and Electrical Runout. You can read more about runout on prosig.com here – Rotor Runout Measurement.

We are often asked exactly what analysis and information is included  The purpose of this post is to show some of the screens and reports from the Rotor Runout Measurement package. So here goes…

The following screenshot (Figure 2) shows comparison of runout traces. Maybe from different locations or same location but from different times.  It could also be from different rotors.

One trace could also be the difference between the other two, for example the difference between a trace measured from an eddy current probe and one from an LVDT probe, the mechanical runout, would produce a trace representing the Electrical Runout. In this example the red trace is from an LVDT and the blue from an eddy probe. The resultant difference is shown as the black trace which represents the electrical runout.
