The latest editions of this text provide a comprehensive roadmap for technicians and engineers looking to master the art and science of field balancing. The Significance of Victor Wowk’s Methodology
If you're looking for a new edition of the book, I recommend checking with the publisher or online bookstores for the latest information on availability and pricing.
For long, slender rotors, the static-couple method helps isolate different types of imbalances, ensuring the rotor is balanced both in its center of gravity and against rocking motions. 4. Overhung and Flexible Rotor Balancing

The mass center is on the shaft centerline, but the principal inertia axis is tilted. It only appears during rotation. The latest editions of this text provide a
Victor Wowk’s book is unique because it covers the low-tech solutions (for when you have no instruments) and the high-tech methods (for turbo-machinery).
Using modern vibration analyzers, the phase and amplitude changes are recorded.
Victor Wowk's company, Machine Dynamics, Inc. , lists his full textbook series and offers a free introductory tutorial on machine vibration diagnosis. : Calculating dynamic variations as shafts pass through
Suitable for many standard rotating applications.
In his latest work, Victor Wowk shares new insights and best practices in machinery vibration balancing, including:
Separates unbalance into a single static force and an opposing angular couple.
