The invention relates to a stator core (1) for an electronically commutated DC motor comprising an internal rotor, having several radially inwardly directed pole cores (2), which at their periphery are integral with back iron segments (3), and the back iron segments (3) are integral with adjacent back iron segments (3) via webs (4), wherein the back iron segments (3) alternate with the webs (4), and jointly form a seamlessly closed one-piece ring. The problem addressed by the invention is that of ensuring that in case of a stator core of this class, upon a reduction of the stator diameter and reduction of the pole distances after a winding, a clearly defined end position of the adjoining regions can be assumed, and that for this process step, only minimal forces are necessary, in which damage to the stator core is not to be expected, and that at the end of the process only a very small and uniform air gap remains at a lowest possible spring-back. This problem is solved by means of the characteristic of claim 1 and the method steps of claim 7. |
