Title: Clamping and alignment of core laminations - comprising mating hollows and projections pressed into each plate
Inventor: REIF DIETER
IPC: H02K1/06
Filed: 1976-10-06
Abstract: The application is mainly to the construction of small cores, for example for miniature motors. The method of construction provides a means for accurately locating the laminations wrt each other and also for finally locking them together without using any additional materials. Each lamination (1) has formed into it a series of lugs (2) which project beyond the surface but remain joined at least at one point to the plate. The cut away part leaves an opening (15) with a boundary (21). When the laminations are stacked the lugs (2) of one plate register with the openings (15) in the plate below by bearing against the boundary (21). A complete stack can thus be assembled accurately without the need for building tools. When completed the lugs of the outermost laminations can be deformed in a pressing operation so that an interference fit results between lugs and openings thus locking the stack solidly together.
