Abstract
A method for manufacturing an electric machine having a stack of magnetic laminations including a stack of green blanks. A first green blank of the stack is printed. A separating layer is applied to the first green blank. At least a second green blank of a magnetic lamination is printed onto the first green blank with the separating layer. The green blanks are jointly sintered.
Claims8
A method for manufacturing an electric machine including a stack of magnetic laminations, the method comprising:
- printing a first green blank of the stack of magnetic laminations;
- wherein green blanks of the stack of magnetic laminations include an n-fold rotational symmetry;
- applying a first separating layer to the first green blank;
- rotating the first green blank by an angle of 360°/n or by a multiple of the angle;
- printing at least a second green blank of the stack of magnetic laminations onto the first separating layer of the first green blank;
- and
- jointly sintering at least the first green blank and the second green blank of the stack of magnetic laminations.
