MULTI-LAYER CYLINDRICAL WINDING Russian patent published in 2018 - IPC H01F27/28 

FIELD: electricity.

SUBSTANCE: multilayer cylindrical winding contains m series-connected layers, each of which represents one turn located in the radial direction in such a way that the first layer is closest of the layers to the axis of winding, and m-th layer is the furthest from the axis. Two additional turns of p parallel wires are connected top wires of the m-th layer. Each of them is placed on the corresponding end face in the radial direction as follows: the first and n-th wires are located in the first layer closest to the axis of the winding at its respective ends. The second and (n-1)-th wires are placed on their respective end faces of the second, following the first layer, layer, the third and (n-2)-th wires are placed in the third from the axis layer of winding, etc. so that the p-th and (n-p+1) wires are placed in p-th layer at the respective end faces of where n is any integer greater than two; m is any valid integer greater than one; p is integer chosen from the ratio of 1<p<n.

EFFECT: alignment of the axial component of the scattering magnetic field.
