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.
