There are two primary types of balancing:
Measurement and Analysis serves as a broader introduction to the entire field of vibration analysis, touching on balancing and alignment without the deep dive. Alignment focuses specifically on the critical task of shaft alignment. Balancing is the comprehensive, dedicated guide to the specific topic of correcting rotor imbalance.
"Machinery Vibration: Balancing" by Victor Wowk is a comprehensive 1994 guide (reprinted 1998) designed for field engineers focusing on practical, on-site vibration reduction methods. The text covers single and two-plane balancing, flexible-rotor techniques, and instrumentation for effective machine diagnostics.

F=m⋅r⋅ω2cap F equals m center dot r center dot omega squared = Centrifugal force = Unbalanced mass weight = Distance from the center of rotation (radius) = Angular velocity (rotational speed) Because the velocity component ( There are two primary types of balancing: Measurement
For analysts using modern vibration analyzers, Wowk’s treatment of is essential. The standard balancing formula that appears in his writings is used to convert raw vibration amplitude and phase data into corrective mass amounts:
The most common real-world scenario, combining both static and coupled unbalance. The inertia axis is both tilted and offset from the geometric centerline. Resolving dynamic unbalance necessitates taking multi-plane measurements while the machine operates at speed.
