MULTIPHASE STATOR WINDING ON PRINTED CIRCUIT BOARD Russian patent published in 2024 - IPC H02K3/26 

FIELD: electric power industry.

SUBSTANCE: multiphase stator winding on printed-circuit board is made in the form of multilayer printed-circuit board with coils in phase winding according to the number of poles of electric machine. Each coil consists of support part [3] on main layer [1] and mating part [4] on complementary layer [2]; support [3] and mating [4] parts of coils form pairs [5] and [6] on their layers alternating and connected to corresponding parts of other coils. Coils are connected to each other in anti-sequential manner, namely in a pair of support parts on the main layer of the coil the beginning is connected to the beginning, and in a pair of mating parts on the complementary layer the end is connected to the end. Jumper between the support parts of the first [7] and the last [8] coils is replaced with taps to the output terminals of the beginning and the end of the phase winding.

EFFECT: reduction of active resistance of winding and reduction of overall dimensions of coils and winding.
