Abstract (en)

[origin: WO2018145678A1] The invention relates to a printed circuit board for an electric motor, comprising a coil (2) formed from at least one spiral-shaped conductor track (3) extending in a layer of the printed circuit board (1), characterised by a coil core (4) consisting of a ferromagnetic or ferrimagnetic material, extending in a direction perpendicular to the layer, the coil core (4) being arranged entirely in the printed circuit board (1) and electrically insulated from the surroundings of the printed circuit board (1). The invention also relates to a method for producing a printed circuit board (1) for an electric motor, comprising the following steps: producing a coil (2) formed from at least one spiral-shaped conductor track (3) extending in a layer of the printed circuit board (1); producing a coil core (4) consisting of a ferromagnetic material, which extends in a direction perpendicular to the layer; arranging the coil core (4) entirely inside the printed circuit board (1); and electrically insulating the coil core (4) from the surroundings of the printed circuit board (1).
