SYNCHRONOUS MACHINE WITH ANISOTROPIC MAGNETIC CONDUCTIVITY OF ROTOR Russian patent published in 2015 - IPC H02K19/20 H02K1/22 

FIELD: electricity.

SUBSTANCE: invention is referred to reactive synchronous machines and may be used as a synchronous electric generator or synchronous electric motor. The synchronous electric motor comprises the stator with magnet core and stator electric windings, end shields and rotor made cylindrical and assembled of ferromagnetic sheets with stacking along the machine shaft axis fixed at the bases of the cylindrical active part to the shaft flanges. Between the rotor ferromagnetic sheets there are uniform air gaps. The rotor of synchronous electrical machine may be performed of material with anisotropic magnetic conductivity in the machine diametrical plane. Thickness of sheets and distance between them may be different to ensure the required concentration of the magnetic field lines.

EFFECT: simplifying rotor design of the synchronous electrical machine, ensuring sinusoidal shape of magnetising force distribution curve along the working gap and ad result improving efficiency of its operation as well as energy performance.
