Abstract: A method which involves aligning a stack of a plurality of loose laminations so that clamp bolt holes therein are held in an accurately aligned condition while the stack is compressed (in the vicinity of the bolt holes) between pads that simulate mounting pads in a compressor, and a means for applying a force localized in the bolt hole regions. The compressive forces are preselected to simulate and closely approximate the compressive forces that ultimately will be applied to the bolt hole regions under the heads of mounting bolts in a compressor. Since the stack is initially aligned before the compressive forces are applied and while the laminations are free to shift relative to one another, the various eccentricities and dimensional variations between the bore and bolt holes are transferred to the bore. Then, while the stack is held with the preselected compressive forces, the bore is shaped to be concentric relative to the bolt holes.

A shaft is fitted coaxially in the base portion of the plastic resin body and extends through a larger diameter central bore of the body, centrally of the commutator segments. The gaps communicate with the annular space between this bore and the shaft, for cleaning out of particulate debris by centrifugal force.
