A magnetic bearing assembly for a rotary machine, having a rotor circuit (17) and a stator magnetic circuit (18) secured to a stationary support element (26) having at least one body of ferromagnetic material (22) and at least one coil (20), both being fitted in a protective annular housing (24) leaving uncovered a surface of revolution (22a) of said ferromagnetic body (22) and a surface of revolution (20a) of said one coil (20) facing a surface of revolution (16d, 16e) of the rotor circuit (17). The bearing assembly (10) comprises at least one row of blades (30, 32) secured on the rotor circuit (17) to generate a flow of fluid to cool the active magnetic bearing (10). |
