ELECTRIC MACHINE ROTOR Russian patent published in 2017 - IPC H02K1/27 H02K1/28 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electrical engineering. The rotor is made in the form of a cylindrical shaft of a nonmagnetic material having a longitudinal radial cavities equidistant from each other and the magnetic strips placed therein, in parallel to the rotor axis. The shaft is made from disks of equal resistance with the same outer diameter, which are rigidly fastened to each other by rim end surfaces, the width of which exceeds the radially oriented size of section of longitudinal radial through cavities made by the perimeter of the disk rim equidistant from each other. Longitudinal radial cavities of all the discs are and coaxial and comprise through channels having no communication with the outer surface of the disc rim. Sections of the through channels surface facing it and the axis of the rotor rotation are rounded, and the radius of this curvature is smaller than the radius of curvature of the outer surface of the disc rim. Magnetic strips sections facing the outer surface of the rotor are congruent to the surface of channels, and their opposing sections are flattened. Magnetic strips are magnetized radially.

EFFECT: increasing the strength of the rotor, reducing the additional losses and parasitic moments caused by the higher harmonics of the inductor magnetic field.
