ROTOR OF ROTARY DYNAMO-ELECTRIC MACHINE WITH EXCITATION FROM PERMANENT MAGNETS AND ITS APPLICATION Russian patent published in 2019 - IPC H02K1/27 H02K1/32 H02K9/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular, to the rotor design with cooling channels. Rotor comprises a cup-like bearing assembly having at least one cylindrical wall and made as a whole. Bearing unit includes bearing structure, which is made as a whole with this bearing unit, on outer perimeter of wall of which there are permanent magnets. Bearing unit in wall has essentially axially cooling channels. When viewed in circumferential direction, cooling channels are closed and/or open radially from the outside, and on one axial end of said bearing assembly they come out into a ledge made integral with cooling channels, this bearing assembly and bearing structure. At that, said cooling channels are designed so that radial fan effect is generated during rotor rotation.

EFFECT: improving cooling efficiency of permanent magnets of rotor.
