FIELD: electric engineering. SUBSTANCE: device has at least two layers of conductor of electric current, which generates electromagnetic flow. Each layer is designed with depth which is equal to one dimension of cross section of conductor for example to its diameter. conductors in each layer are arranged so that electric current in all conductors of one layer in each moment has same direction, while in conductors of each adjacent layer current is opposite. In addition ferromagnetic material is located between each pair of adjacent layers of conductors. EFFECT: increased efficiency of usage of conductor and ferromagnetic material, increased efficiency of conversion of electric current to magnetic flow power, increased reliability due to decreased probability of short circuit between turns. |
