STATOR OF INVERTED AXIAL ELECTRIC MACHINE WITH WINDINGS ON PRINTED CIRCUIT BOARDS Russian patent published in 2022 - IPC H02K3/26 H02K3/28 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering. The stator of an inverted axial electric machine with windings on printed circuit boards contains a three-phase winding in the form of electrically conductive tracks grouped into series-connected coils on unified active layers of stator printed circuit boards, with output terminals for the beginning and end of the winding located inside the printed circuit board area between the inner boundary of the winding and the shaft, at an angular distance of 360 electrical degrees from each other. On one active layer there is a winding of only one phase, which is formed by shifting the layer by -120, or 0, or +120 electrical degrees relative to the base position of the layer. The windings of the active layers are connected in a single circuit of the three-phase stator winding in series and/or in parallel. To do this, the outputs of the beginning and end of the phase windings of the layers are connected by soldering interlayer jumpers installed in the switching holes in the area of the printed circuit board adjacent to the shaft, at an angular distance of 120 electrical degrees from each other, to the output terminals of the phase windings of the active layers.

EFFECT: providing the possibility of a flexible layout of the stator winding depending on the technical requirements, simplifying the assembly and switching of the three-phase stator winding.
