Abstract:
A method of manufacturing a motor core having a plurality of metallic plate-like laminations, the method comprising the steps of:juxtaposing the laminations in a stacked relation along a central axis, the laminations having a central aperture and an outer peripheral surface;placing the laminations over an alignment post of an alignment fixture to align the laminations, until the laminations rest upon a base portion of the alignment fixture such that substantially no compressive force is applied to the laminations;the alignment post having an outside diameter substantially equal to an inside diameter of the central aperture so as to form a slip fit therebetween to urge the laminations into full alignment;flowing at least one bead of cyanoacrylate adhesive material along the outer peripheral surface of the laminations in a generally vertical orientation between a top lamination and a bottom lamination, the adhesive material wicking between the laminations, and when cured, fixing the laminations in a predetermined non-moving orientation;removing the laminations from the alignment fixture; andapplying windings to the laminations.
