3. The "Slow Roll" Compensation

A critical lesson in the PDF is compensating for "slow roll" runout—the mechanical or electrical noise that appears at low speed. Wowk teaches how to subtract this vectorially to find the true dynamic imbalance. Training: Victor Wowk's firm, Machine Dynamics , offers

Wowk provides the geometry formulas and graphical vector solutions (using polar graphs) so you can do this with a calculator and paper—no software license required.

• Step 1: Measure Initial Vibration (Amplitude & Phase).
• Step 2: Add a Trial Weight at a known location.
• Step 3: Measure the new vibration.
• Step 4: Calculate the "Effect" (Vector subtraction).
• Step 5: Compute the required Correction Weight and Angular Location.
