description A process for producing a ferromagnetic core for electric motors formed by a plurality of laminated segments (SI-SN) arranged in closed circular configuration is described. The ferromagnetic core comprises a first auxiliary layer (L1; LM; Lj') of laminations having a projecting pin (23, 43) near a convex portion (21, 41) at one end of the yoke base (12) of the laminations that form each of the laminated segments and a concave portion (22, 32, 42) at the opposite end of the yoke base (12) of the laminations that form each of the laminated segments in the first auxiliary layer (L1; LM; Lj') of laminations, and a second auxiliary layer(L2; LM; Lj') of laminations having an opening (33) near the convex portion (31) at one end of the yoke base (12) of the laminations that form each of the laminated segments. The pins of the first auxiliary layer (L1; LM; Lj') of laminations are engaged in the openings (33) of the second auxiliary layer (L2; LM; Lj') of laminations.
