ABSTRACT:
The stator laminations for a dynamoelectric machine may be first stacked in a concentric orientation and then skewed in a controlled manner after the stator is wound, with a pair of elliptically shaped alignment slots in each lamination holding a pair of alignment bolts of generally circular cross-section, such that the laminations may be first stacked onto the alignment bolts and then skewed by pivoting the alignment bolts, thereby causing relative radial movement between the laminations and the bolts as the bolts are permitted to slide within the elliptical alignment slots. In a second embodiment, a pair of radial projections on the stator laminations and a pair of channel members which surround the radial projections permit relative radial movement and canting of the projections with respect to the channel member as the channel members are pivoted to skew the stator lamination stack.
