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.

The need for training normally falls into two categories; using XLRotor and general rotordynamic analysis.

For many, the Excel interface makes XLRotor intuitive enough to use with little to no training on the
XLRotor software itself. Any of the many included example files can be used to get yourself started immediately with your analysis. Contextual and searchable HELP gives immediately useful information from any screen.

XLRotor comes with a comprehensive multi-part tutorial in pdf files that are launched from the Windows Start button (Start/All Programs/XLRotor/XLRotor Tutorial) or from the XLRotor ribbon tab in Excel (look in the Help group on the far right of the ribbon). The first part of the tutorial quickly covers the basics that will make most users productive in just a few minutes.

For custom training on XLRotor, contact us. A typical course is 3 days at the customer site for 3-10 engineers. The content is oriented to XLRotor users and includes a combination of rotordynamics concepts and advanced XLRotor use. Additional XLRotor licenses are provided for every student for self-study in advance and to use during the course.

Training in general rotordynamic analysis is a complex topic, and can be obtained from books, university classes or short courses. For some recommended books, visit and click on Booklist. For university classes or short courses, use an internet search engine.
