Abstract
A stator/rotor lamination sheet for a stator/rotor lamination of generators and electric motors has spacers, wherein the spacers are monolithic lamination sections that are bent out of a lamination sheet plane about a bending edge and create corresponding recesses in the lamination sheet, wherein the spacers transversely protrude from the lamination sheet plane. A method for manufacturing the stator/rotor lamination sheet provides that a stator/rotor lamination sheet is punched out of a metal sheet; lamination sections are partially punched out out of the metal sheet; and the partially punched-out lamination sections are bent out of a lamination sheet plane of the lamination sheet to form spacers of the lamination sheet.
