Title: MOVABLE STATOR CORE
Abstract:
The invention relates to a sheet metal lamination, in particular for forming a stator core for an electromagnetic machine. The sheet metal lamination contains a front side and a back side; an annular element, which has a center point, an inside, and an outside; and at least a first pole element and a second pole element, which are each positioned on the inside of the annular element and extend in a radial direction toward the center point of the annular element. The sheet metal lamination contains at least one orienting device for orienting the sheet metal lamination in relation to a second adjacent sheet metal lamination. The invention further relates to a method for producing a stator core comprising a plurality of such sheet metal laminations, comprising the steps of lining up the sheet metal laminations against each other in order to form a cylindrical stator core, wherein the orienting device of a sheet metal lamination is arranged at a predetermined angle to the orienting device of a subsequent sheet metal lamination, orienting the individual sheet metal laminations in relation to each other by means of the orienting device of the corresponding sheet metal laminations and a reference device, and rotating the individual sheet metal laminations in relation to each other by means of the first connecting element and the second connecting element of the corresponding sheet metal laminations.
