FIELD: electricity.
SUBSTANCE: invention relates to a sheet of electrical steel for an electrical machine, the main body of which is a single sheet of magnetized material with several recesses. In order to achieve technical result, electrotechnical sheet (9) for electric machine is provided, the main body of which is single sheet (5) of magnetisable material, wherein single sheet (5) has several recesses (1). At least one web (10) is provided in each of recesses (1), wherein web (10) is printed by 3D printing from non-magnetisable material.
EFFECT: increased magnetic efficiency, particularly, of sheet metal of rotor, increased rotor rpm with maintenance of stabilization relative to centrifugal force, suppression of magnetic flow of dissipation with increase of efficiency of electric machine as a whole.
