    摘要: A rotary pump (PP) for taking in a liquid such as a hydrocarbon comprises a pump wheel (1) secured to a rotor (4) which is immersed in a portion of the liquid taken in by the pump. A motor (11) having a stator element (111) mounted in a case (5) and a rotor element (110) mounted on the rotor (4) serves to cause the rotor (4) to rotate about an axis (40). Radial magnetic bearings (7, 8) and axial magnetic bearings (9, 10) support and guide the rotor (4) inside an enclosure (6). A jacket (61) is provided to protect the stator element (111) of the motor (11) from the liquid. The pump is characterized in that the rotor (4) has at least one groove (45, 46) in an outer surface that is covered by the liquid, particularly to reduce the inertial effects due to the liquid.

    摘要: A turbo-machine for compressing or expanding a fluid comprises a housing (201), a rotary shaft (203), an electric machine (207), an impeller (202) mounted at an end of the rotary shaft (203), radial magnetic bearings (208), an axial magnetic bearing (210), an axial detector (240), radial detectors (209), a control circuit, and auxiliary bearings (290). An auxiliary bearing (290) is integrated within a stator portion (211, 212) of the axial magnetic bearing (210) and this stator portion (211, 212) of the axial magnetic bearing (210) is located opposite a rotor armature (220) of the axial magnetic bearing (210). The rotor armature (220) is made of iron or of a material which is adapted to be attracted in a magnetic field and is constituted by a rear face (221) of the impeller (202).
