INDUCTION DEVICE WINDING AND METHOD OF ITS MANUFACTURE Russian patent published in 2018 - IPC H01F27/28 H01F41/69 

FIELD: electricity.

SUBSTANCE: induction device winding comprises n series-connected coils, each of which contains m parallel conductors located in the axial direction. At least one of the m parallel conductors is fixed to the outer end of the coil. Sleeves of electrically conductive material are inserted, placed on the inner diametre of each even coil, as well as on the external transitions between the even and odd coils, ensuring the connection of the corresponding coils with each other. In the method for manufacturing the induction device winding, n coils m are wound by parallel conductors coming from the winding reels, and the coils are serially connected. Before the winding of the coils, transitions between the odd and even coils are formed, the odd (first) coil is wound in one direction, the ends (m-m₁) of the conductors are cut off, m₁ conductors perform one turn, placing it on the end of the first coil, m₁ conductors are cut off, the next even coil is wound in the opposite direction. The winding procedure is then repeated in a similar manner, including the penultimate coil. The last coil is similar to the first one. Then, external transitions are carried out using sleeves of electrically conductive material, where n is any integer greater than two; m is any integer greater than one, m₁ is any integer, 1≤m₁<m.

EFFECT: expansion of functional capabilities with relative simplicity of production.
