SYNCHRONOUS ELECTRIC MOTOR WITH ANISOTROPIC MAGNETIC CONDUCTIVITY OF THE ROTOR Russian patent published in 2018 - IPC H02K1/24 H02K19/14 H02K19/20 

FIELD: electrical equipment.

SUBSTANCE: invention relates to synchronous reactive electric motors. Synchronous electric motor comprises a stator with a magnetic core and windings, bearings shields and a cylindrical rotor consisting of a rotor shaft, fastening studs and a rotor magnetic core assembled from the ferromagnetic material sheets with gaps spaced by insulation and stacking made along the machine shaft axis. Rotor additionally contains current conductive non-magnetic buses, which number is equal to the number of the electric machine poles, and two connecting rings. Rotor shaft and fastening studs are made of non-magnetic and non-conductive material. In the machine transverse plane ferromagnetic material sheets have a symmetrical shape. Each of the current conductive busbars is located throughout the volume in the fastening recesses of the last sheets of each rotor pole package. Two connecting rings are electrically connecting the current conductive busbars in the bases of the rotor cylindrical part.

EFFECT: technical result is an increase in the starting torque, providing the possibility of reversing, reducing the electromagnetic moment pulsation, simplification of the rotor design and manufacturing technology.
