ROTOR OF ELECTRIC MACHINE WITH MANUFACTURED, IN TERMS OF GRANULATE, SHORT-CIRCUITED CAGE Russian patent published in 2017 - IPC H02K15/02 H02K17/16 H02K3/02 

FIELD: electricity.

SUBSTANCE: rotor has a rotary core (1) of core material, arranged concentrically to the axis, comprising grooves (2) extending substantially axially. The core (1) at each axial end of the grooves (2) has a corresponding annular recess (3) arranged concentrically with the rotor axis and connecting the grooves (2). The core (1) has a diffusion layer (4), which comprises a diffusion material and covers at least partially the corresponding surface of the grooves (2) and / or the annular recess (3). Granulate (5) of an electrically conductive material is introduced into the grooves (2) and/or the corresponding annular recess (3), which is connected with material bringing to the rotor core (1) in case of heat supply and pressure application.

EFFECT: improving the mechanical properties of the rotor.
