Abstract
Various embodiments include a method for manufacturing a magnetic sheet comprising: positioning a nonmagnetic sheet with recessed regions; filling the recessed regions with a soft-magnetic material using additive manufacturing; and fixing the soft-magnetic material to the sheet in a material-bonded manner.
Claims6
A method for manufacturing a stack of magnetic sheets, the method comprising:
- fabricating individual non-magnetic sheets by punching and/or cutting, including creating recessed regions along a flat extension of the non-magnetic sheets;
- filling the recessed regions of the fabricated individual sheets with soft-magnetic material by additive manufacturing to create material bonds at connection points;
- tempering the filled individual sheets;
- and
- stacking the tempered individual sheets.
