Abstract
A method and a tool for manufacturing a laminated core of an electric machine includes a fluidic component being applied on at least one portion of at least one side of a metal sheet using at least one applicator employing an inkjet printing technique. At least one blank of the at least one metal sheet including the at least one fluidic component is die cut. Multiple blanks are aligned with regard to each other for forming the laminated core.
Claims20
A method for manufacturing a laminated core of an electric machine, the method comprising:
- providing at least one metal sheet;
- applying at least one fluidic component to at least one portion of at least one side of the at least one metal sheet using at least one applicator, the at least one applicator employing an inkjet printing technique;
- die cutting at least one blank of the at least one metal sheet including the at least one fluidic component;
- and
- aligning multiple blanks to each other for forming the laminated core,
- wherein the at least one fluidic component is configured to establish a bonding between adjacent laminations, and the at least one fluidic component is applied to an area of the at least one metal sheet, and wherein an amount of the at least one fluidic component varies across the area according to a predetermined spatial pattern.
A tool for manufacturing a laminated core of an electric machine, the tool comprising:
- at least one applicator;
- a progressive die stage;
- a die cutting stage;
- and
- a control device, wherein the control device is coupled to the at least one applicator, the progressive die stage, and the die cutting stage,
- wherein the at least one applicator is configured to apply at least one fluidic component to at least one portion of at least one side of at least one metal sheet employing an inkjet printing technique,
- wherein the progressive die stage is configured to apply stamp features to the at least one metal sheet, and
- wherein the die cutting stage is configured to die cut at least one blank of the at least one metal sheet including the at least one fluidic component and to align multiple blanks to each other for forming the laminated core.
A method for manufacturing a laminated core of an electric machine, the method comprising:
- providing at least one metal sheet;
- applying at least one fluidic component to at least one portion of at least one side of the at least one metal sheet using at least one applicator employing an inkjet printing technique;
- die cutting at least one blank of the at least one metal sheet including the at least one fluidic component;
- and
- aligning multiple blanks with regard to each other for forming the laminated core,
- wherein the at least one fluidic component is configured to establish a bonding between adjacent laminations,
- wherein the at least one fluidic component is applied to an area of the at least one metal sheet, and wherein an amount of the at least one fluidic component varies across the area according to a predetermined spatial pattern, and
- wherein at least one mark is applied to the at least one metal sheet by applying the at least one fluidic component, and wherein the at least one mark provides at least one of an alignment labelling and an identification labelling to the at least one portion of the at least one metal sheet.
