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.
A stator/rotor lamination sheet for a stator/rotor lamination core of generators and electric motors, the stator/rotor lamination sheet comprising 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, wherein each spacer has a radial extending therethrough and has a length, wherein each spacer extends across the length at an angle relative to the radial, and wherein each spacer is positioned at a slant relative to a circumference of the stator/rotor lamination sheet, wherein each spacer has a free edge pointing away from the stator/rotor lamination sheet, and the free edge is a contact surface configured to support a neighboring lamination sheet of a laminated core section when the stator/rotor lamination sheet is arranged in a stator/rotor lamination core.
A stator/rotor lamination core comprising laminated core sections, the laminated core sections each comprising stator/rotor lamination sheets that are immediately contacting each other and are immediately connected to each other, wherein between two neighboring laminated core sections, respectively, ventilation channels are arranged, wherein the ventilation channels are formed by spacers that are monolithic lamination sections bent out of a lamination sheet plane of a stator/rotor lamination sheet of the first of the two neighboring laminated core sections that is facing the second of the two neighboring laminated core sections, wherein the spacers support the second of the two neighboring laminated core sections.
