Abstract

The structure of this alignment device provides for the fixturing and alignment of the rotor and stator portions of a motor, of the type used to rotate a disk drive spindle assembly, during shipping and mounting. The aligning shim or fixture 5 is a thin strip of plastic material, such as polyethylene, having a thickness equivalent to the clearance to be established between the stator, and rotor of the motor. The solid strip portion 6 provides the clearance between rotor and stator, and a series of guide tabs 7 bend outwardly when the strip is placed within the motor stator cavity to enable the rotor to be guided into the assembled condition. The strip is debossed along line 8 at the base of the tabs to form a hinge location and cause the tabs to fold toward the side debossed.
