RADIAL MAGNETIC BEARING FOR ROTOR MAGNETIC SUPPORT Russian patent published in 2015 - IPC F16C32/04 H02K3/493 

FIELD: machine building.

SUBSTANCE: radial magnetic bearing (1") is designed as opposite unlike poles bearing and has stator (2), stator (2) has magnetic-conductive stator element (4) located with passing around rotor (5), element (4) on its side (12) exposed to rotor (5) has recesses (10) passing in axial direction (X) of stator element (4), in which electric wires (8a, 9a) of coils (8, 9) are located. Coils (8, 9) are meant for generation of magnetic fields which retain rotor (5) with holding in air-gap (7) located between rotor (5) and stator (2). Wires (8a, 9a) are located in recesses (10), so that there is free space in recesses (10) between wires (8a, 9a) and air-gap (7). In free space there located is magnetic conductive filling element.

EFFECT: due to meaningful measures, during transitions from one magnetic field to another magnetic field there achieved is more smooth passage of magnetic flux density component passing in radial direction, thus resulting in reduction of eddy currents induced in rotor.
