Abstract: A testing apparatus includes a chamber, having an interior maintained at a predetermined pressure, a rotor rotatably disposed within the interior of the chamber, and a sensor disposed within the interior of the chamber. When the rotor rotates, the at least one sensor measures a testing characteristic of an object disposed within the interior of the chamber as the object interacts with the rotating rotor. A method includes setting a predetermined pressure of a chamber, rotating a rotor, and maintaining a gap between a surface of an object to be tested and a surface of the rotor by adjusting, with an actuator, the object to be tested or the rotor based upon a change, as measured by a laser, in the dimension of the object to be tested or the rotor.

Abstract: A channel segment for a track of a mover device is provided, the channel segment comprising: opposite ends joined by a body forming a magnetic flux pathway between the opposite ends, the magnetic flux pathway being one or more of C-shaped, U-shaped and horseshoe shaped between the opposite ends, the opposite ends forming respective transverse magnetic flux pathways about perpendicular to the magnetic flux pathway; laminations of ferromagnetic material forming the body, the laminations about parallel to the magnetic flux pathway and about perpendicular to the respective transverse magnetic flux pathways; shear pins through the laminations, the shear pins positioned to reduce eddy currents one or more of in and around the shear pins; and a retention mechanism at the opposite ends, the retention mechanism configured to transversely fasten the laminations together at the opposite ends while remaining insulated from each other.
