ROTOR AND JET INDUCTOR ENGINE Russian patent published in 2017 - IPC H02K1/24 H02K15/02 H02K19/06 

FIELD: engines and pumps.

SUBSTANCE: rotor for a synchronous rotary electric machine comprises a rotor shaft and a soft magnetic element of cylindrical shape, mounted coaxially on the rotary axis and fixed in both axial and tangential direction. Said soft magnetic element has recesses forming an even number of salient magnetic poles to create barriers for the magnetic flux and the optimization of the magnetic permeability ratio along the axes d and q. Wherein at least one recess is at least partially filled with a diamagnetic or a paramagnetic medium instead of air. At least one spacer element is located on the rotary axis. Wherein the gap lying above the spacer element is at least partially filled with a paramagnetic or diamagnetic medium, said paramagnetic or diamagnetic medium forming an integral body.

EFFECT: improved magnetic characteristics of the rotor.
