STATOR OF AN AXIAL THREE-PHASE ELECTRIC MACHINE WITH WINDINGS ON PRINTED CIRCUIT BOARDS Russian patent published in 2022 - IPC H02K3/26 H02K3/28 H02K1/12 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. The stator of an axial three-phase electric machine with windings on printed circuit boards contains a winding in the form of electrically conductive tracks grouped into coils on unified active layers of stator printed circuit boards. The output terminals of the beginning and end of the winding at the end of the printed circuit boards are located at an angular distance from each other equal to 360 electrical degrees. On one unified active layer there is a winding of only one phase and consists of coils connected in series. The phase winding of the layer is formed due to its shift by -120, or 0, or +120 electrical degrees relative to the base position. The active layers are connected in a single circuit of a three-phase stator winding in series and/or in parallel. To do this, the conclusions of the beginning and end of the phase windings of the layers are connected by soldering jumpers installed in the switching recesses at the end of the printed circuit boards, located at an angular distance from each other equal to 120 electrical degrees.

EFFECT: increasing reliability and maintainability due to the possibility of a flexible layout of the stator winding and building up phase layers depending on the required parameters of the electrical machine.
