Primary part of an electrical machine, electrical machine and method for producing a primary part

摘要

The present invention relates to a primary part (02) of an electrical machine (01, 25) comprising a multilayer printed circuit board (07) with at least two spaced-over, electrically conductive layers (08), wherein the electrically conductive layers (08) comprise at least one coil (08). 11, 12, 18), at least one dielectric layer (09), which is arranged between the electrically conductive layers (08), at least two magnetically conductive layers (10) spaced apart, each magnetically conductive layer (10) being at least indirectly is arranged adjacent to an electrically conductive layer (08), and connecting means (26) made of a magnetically conductive material for the targeted magnetic connection of the magnetically conductive layers (10). The invention also relates to an electrical machine having such a primary part (02) and to a method for producing a primary part (02).
