Abstract
An apparatus and method for forming laminations for a stacked lamination assembly of a dynamoelectric machine wherein the laminations of the assembly are provided with displacement segments and complimentary openings of slightly larger dimensional size, the segments being configured to abate lateral shifting of adjacent laminations when the segments and compatible openings of the laminations are in nesting relation in a stacked lamination assembly.
Claims8
A stacked lamination assembly for a dynamoelectric machine comprising:
- a plurality of stacked laminations, each of said laminations having lamination displaced segment means of preselected dimensional size and configuration and a complementary opening means of slightly larger preselected dimensional size and compatible configuration to nestingly and freely engagingly receive the lamination displaced segment means of an adjacent lamination in selectively and fully spaced, unconstrained aligned relationship along opposed faces of nesting engagement, each of said lamination displaced segment means being continuously and uninterruptively configured throughout relative the planar face of a lamination from which it is displaced to abate lateral shifting of adjacent laminations beyond the preselected dimensional size difference between the nesting and freely engaging lamination displacement segment means and the complementary opening means of adjacent laminations.
A stacked lamination assembly for a dynamoelectric machine comprising:
- a plurality of stacked stator laminations, each of said stator laminations having a spaced pair of circular continuously and uninterruptively button-shaped displaced segments of preselected dimensional size and configuration and an aligned similarly spaced pair of circular button-shaped openings, said openings being approximately 0.001 inch dimensionally larger throughout of preselected size and compatible configuration to each nestingly and freely engagingly receive one of the two of the spaced pair of lamination displaced segments of an adjacent lamination, said lamination displaced button-shaped segments having a peripheral cylindrical side surface extending substantially normal from the planar face of the lamination from which it extends to abate lateral shifting of adjacent laminations beyond the preselected dimensional approximately 0.001 size difference between the nesting and freely engaging lamination displacement segments and the complimentary openings of an adjacent lamination, each of said stacked laminations including inner and outer diameters formed simultaneously with said pair of displaced segments and said aligned pair of openings to enhance alignment of stacked laminations.
