SYNCHRONOUS ELECTRIC MACHINE WITH ANISOTROPIC MAGNETIC CONDUCTIVITY OF ROTOR Russian patent published in 2019 - IPC H02K1/24 H02K19/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to reactive synchronous electric machines. Synchronous electric machine with anisotropic magnetic conductivity of rotor comprises stator with magnetic conductor and stator electric windings, bearing shields and rotor, which is imitated across the shaft axis of the machine and contains sheets of ferromagnetic material. Sheets of ferromagnetic material are tightened by pins and two washers located on the edges of the active part of the rotor. Diameter of the active part of the rotor is equal to the diameter of the washers. Pins are arranged parallel symmetrically relative to rotor axis and pass through all sheets of ferromagnetic material and washer and tighten pack with the help of nuts. Rotor is made in the form of separate poles consisting of a pack of sheets of laminated ferromagnetic material and separated from the other rotor poles by an air gap. Pins are made from non-magnetic material and pass through cutouts of each of poles for their attachment to washers made from non-magnetic material. Rotor shaft is composed of two parts, each of which is fixed to its washer.

EFFECT: improved manufacturability of rotor manufacturing, increased efficiency of machine operation.
