Abstract:
A method of producing a laminated core of a stator of an electric motor, includes at least one laminated core of a stator formed by stacked sheet-metal laminates, which have mechanical individual poles and of poles connected in the circumferential direction of the stator, at least one pole shank and at least one pole shoe facing a rotor. The sheet-metal laminates are configured with indentations and protrusions and, as a result, the sheet-metal laminates form the laminated core of the stator by interengagement of the indentations and protrusions. The mechanical poles of the laminated core of the stator have windings, and webs are provided between the poles to connect the connected mechanical poles in the circumferential direction. The axial set-up of the sheet-metal laminates of the laminated core of the stator has a predeterminable alternating succession of poles with a connecting web and poles without a connecting web.
