Abstract

An armature is limited in its axial movement by a pair of retainer clamps positioned over a bearing that has been press fitted onto the shaft of the armature. The clamps are first secured by bolts through an end cap onto lower surfaces in first recessed regions in the end cap in an orientation to allow insertion of the bearing into the bearing bore of the end cap. The motor is then assembled preventing further direct access to the clamps. After assembly the clamps are first loosened so that they are no longer secured to the surfaces. Next, the bolts are turned in a clockwise direction which first turns the clamps until they hit a vertical wall in the end cap which orients the clamps partially over the bearing, and then the clamps tighten onto the lower surfaces of second recessed regions.
