Abstract
Example embodiments provide an automated test hammer apparatus comprising an impact tip, a bottom plate, an enclosure, a top plate, an electronics cover, magnetic clamps attached to the bottom, an outer radial magnet ring polarized outward from the center, an inner radial magnet ring polarized outward from the center, an outer axial magnet ring polarized downward, and an inner axial magnet ring polarized upward. The automated test hammer apparatus may further comprise a back-iron that supports the magnets of the inner and outer rings and completes the magnetic circuit between them, a load cell connected to the impact tip and connected to the back-iron such that it transmits force from the back-iron to the impact tip, a bobbin, and a coil wound around the bobbin. The current through the coil may interact with the magnetic field of the magnets.
