Build Core Drawing Datums around the Assembly Functions Map Limb Straightness over the Coil’s Entire Travel Keep Scan Registration Drift out of Large Core Measurements When a CMM Probe Moves the Lamination It Measures A Burr Can Move the Datum before It Changes the Dimension Correct the Core and the Gauge for Their Own Temperatures Is the Core Sagging in the Inspection Position? Can Your Point Cloud Detect One Protruding Lamination? Measure a Miter Apex from the Edges That Define It Roundness Numbers Can Penalize the Intended Core Steps Find the Cause of a Core-Stack Taper before Changing the Sheet Count Verify Both T-Joint Edges in One Coordinate System Which Spacer Thickness Defines the Core Cooling Duct? Inspect Step-Lap Offsets while the Layers Are Still Visible Allocate Tolerance to the Coil-Insertion Gauge as Well as the Core Transfer the Core Datum into the Winding Fixture Coordinates Measure Joint Gaps from Photographs without Borrowing the Wrong Scale Turn a Magnetostriction Loop into a Mechanical Source Spectrum Choose a Defensible Maxwell-Stress Surface at a Core Joint Core-Limb Phases Change Where the Sound Adds Up Apply Magnetostrictive Strain Once in the Vibration Model Track Coupled Modes when the Tank Contains Insulating Liquid Core Contact Damping Requires Force–Displacement Phase Harmonic Amplitudes Alone Do Not Define the Magnetic Noise Source Equal Tank-Panel Velocity Does Not Mean Equal Sound Power Use Half-Cycle Symmetry to Investigate DC-Biased Core Vibration A Transformer Enclosure Can Create Its Own Low-Frequency Resonance Validate the Exterior Acoustic Solver before Modeling the Transformer Home
