摘要： A compact electric centrifugal compressor particularly suitable for a heat ventilation air conditioning system for vehicles provides a motor portion (20) and a centrifugal compressor portion (10) driven by the motor portion (20) through a shaft (15). The motor portion includes first and second radial bearingless motors (140, 150). An active axial magnetic bearing or an axial bearingless motor (130) is located between the first and second radial bearingless motors (140, 150). The motor portion is further equipped with auxiliary landing bearings (8).

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, a rotary shaft, an electric machine, an impeller mounted at an end of the rotary shaft, radial magnetic bearings, an axial magnetic bearing, an axial detector, radial detectors, a control circuit, and auxiliary bearings. An auxiliary bearing is integrated within a stator portion of the axial magnetic bearing and this stator portion of the axial magnetic bearing is located opposite a rotor armature of the axial magnetic bearing. The rotor armature 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 of the impeller.
