ALTERNATING CURRENT ELECTRIC MACHINE WINDING Russian patent published in 2020 - IPC H02K3/28 H02K17/14 

FIELD: electrical engineering.

SUBSTANCE: invention is related to the field of electric engineering, namely to device of multiphase windings of alternating current electric machines. Claimed m-phase four-zone winding with pole pair number p₀ is made as chain in Z slots, Z=nmp₀q_F, left sides of coils are located in odd slots, and right sides of coils are located in even slots. At that, q_F coils, series-connected within each phase zone τ_F, equal to even number τ_F=Z/(4p₀) are performed at step y_cp equal to plus/minus k₁, where k₁ equals a whole number from natural row 1, 2 …, and when τ_F, which is equal to an odd number, are performed with step y_cp, equal to plus/minus k₂, where k₂ equals a whole number from natural row 0, 1, 2 < … >.

EFFECT: reduced consumption of copper.
