Useful model relates down the field of electrical engineering, in particular to the construction of the rotors of the valve immersible electric motors ([PED]), used before the pumping stations for oil production.Rotor consists of shaft with the fixed on it magnetic system, made in the form of bushing from magnetically hard magnetolayer with the filler from the powder on the basis of rare-earth metals, obtained by extrusion before the magnetic field.Technical result consists before simplification in the construction of rotor and reduction in the labor expense for its production, and also reduction in the total electrical losses in [PED]. 1 [n].[p]. of formula.
