METHOD TO MANUFACTURE MAGNETIC CONDUCTOR Russian patent published in 2011 - IPC H01F41/02 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering, namely, to manufacturing of magnetic conductors from amorphous soft magnetic materials. Method includes winding of tape from amorphous soft magnetic material, its annealing, cooling and application of poly-para-xylylene layer onto cooled wound tape by gas phase deposition with thickness of 1-8 mcm. When conductor is installed into body, a silicon organic compound KLT-30 is applied pointwise onto its inner surface. Tape is annealed in magnetic field: longitudinal, with intensity of 5-30 E, or transverse, with intensity of 10-50 E. Magnetic conductors manufactured by proposed method preserve stable magnetic parameters under climatic and mechanical exposure in the range of temperatures of -60°C -+85 °C, which is the technical result of the invention. Absence of elastic tensions in conductors is confirmed by availability of 15% samples of each batch with high coefficient of squareness Ks=0.95-0.999; Ks of conductors with linear hysteresis loop makes 0.3-0.7; Ks of conductors with perminvar loop ≤0.01.

EFFECT: increased efficiency of method.
