What clients say:

We have been using XLRotor for rotating machinery analysis here at Kato Engineering for the last 15+ years. XLRotor is an important tool in our engineering tool box. The clean Excel based user interface and relative ease of use are just some of the reasons why we use XLRotor. The transient simulation capabilities and bearing stiffness and damping calculation capabilities are additional features that allow for seamless operation in terms of start-to-finish design and simulation capabilities. We have also relied on the timely and knowledgeable technical support.

Three files are available for download—the XLRotor Data Sheet, the XLRotor Tour, and the XLRotor 5-station full-featured evaluation version.

IMPORTANT NOTE: As with all downloadable files on the XLRotor site, the Tour and Demo do NOT include cookies, web beacons, or other intrusive components.

The Full Working Version of Xlrotor

The XLRotor evaluation version is a full working version of XLRotor 5.70, and includes the many example analysis files. It is approximately 151 megabytes in size. Last updated April 17, 2020.

The XLRotor evaluation version is ideal if your goal is to study and learn about rotordynamic analysis.  The evaluation version is limited in that it will permit analysis of models of 5 or fewer stations. However, you can also run any analysis with any of the included example files, many of which are more than 5 stations, as long as the shaft model is not changed (you can change everything else, including the bearings, imbalances, analysis options, etc.).  

Included in the demo is the analysis code XLHydroDyn for design of fluid film bearings. The demo version will run any of the included XLHydroDyn sample workbooks. Anything in these files can be modified and rerun except the journal diameter and pad axial length.

The installation program for the evaluation version will prompt you for a password. The password will be sent to you via email. The XLRotor evaluation version cannot be installed without the password, so enter your email address very carefully. Please let us know if you encounter any problems downloading, installing or running the program (email tech support). An uninstaller is included which can be used to completely remove the program.

By default, XLRotor can and will install without administrator privilege.  You may right-click the setup program and select “Run as Administrator” from the context menu, but this should not be necessary.
