Stator lamination stack indexing and retention

摘要

An electrical device including a housing having an inner surface, a lamination assembly and at least one pin extending from an inner surface of the housing. The lamination assembly has at least one slot therein. The lamination assembly is clocked to a position so that the at least one pin coacts with the at least one slot to rotationally orient the lamination assembly. The at least one pin additionally acts to constrain the lamination assembly from axial removal from the housing thereby rotationally and axially limiting movement of the lamination assembly to a predetermined range of movement within the housing.

主权项

1. An electrical device, comprising:
a housing having an inner surface; a lamination assembly having at least one slot therein; and at least one pin having a width smaller than a length of a corresponding one of said at least one slot, said pin extending from said inner surface of said housing into said at least one slot to be spaced from a surface of said at least one slot such that a gap is formed between said at least one slot and said end and an axial side surface of said at least one pin, said lamination assembly being clocked to a position so that said at least one pin coacts with said at least one slot to rotationally orient said lamination assembly; wherein, prior to fastening said lamination assembly to said housing, said at least one pin limits a range of movement of said lamination assembly within said housing rotationally and axially, including preventing axial removal of said lamination assembly from said housing.
