摘要： The device for magnetically suspending a rotor relative to a structure comprises at least one axial active magnetic bearing with a main electromagnet coil disposed in a stator and having load-bearing surfaces placed facing an armature extending essentially perpendicularly to the axis of the rotor. A device for detecting the axial position of the rotor is associated with circuits for servo-controlling the current carried by the main electromagnet coil. A compensation coil is disposed close to the main electromagnet coil, but in a position that is situated away from the load-bearing surfaces of the stator that co-operate with the rotor armature. The compensation coil is connected in series with the main electromagnet coil, but carries current in the opposite direction to that carried by said main electromagnet coil. The device constitutes an axial abutment of optimized capacity without magnetic leakage.

摘要： The jacketed active magnetic bearing is applied to a rotary machine having a rotor in contact with a process gas and placed in a leaktight enclosure. The magnetic stator is protected by a first jacket of magnetic anti-corrosion material that constitutes a portion of the leaktight enclosure and that is secured to the bearing stator, and the detector stator is protected by a second jacket of non-magnetic anti-corrosion material that constitutes a portion of the leaktight enclosure and that is secured to the detector stator. The bearing armature and the detector armature can be made of a laminated magnetic identical to that of the first jacket.

摘要： The rotary electric machine comprises at least one piece of electric equipment constituted by an overmolded or jacketed electric motor or by an overmolded or jacketed magnetic suspension system. The electric equipment comprises firstly a rotor (102) and secondly a stator (150) having pole pieces (154) and coils (152). The stator (150) is provided with at least one jacket (101) or coating (190) to protect it against an aggressive environment, on its face situated facing the rotor (102). The protective jacket (101) or coating (190) on the face of the stator (150) facing the rotor (102) presents set-back portions (111) set back from the main surfaces (155) defining the airgap (e), these set-back portions (111) being distributed around the stator. The movement of fluid circulating in the airgap around the rotor (102) is thus enhanced.

摘要： The emergency rolling bearing for a rotary machine having magnetic bearings includes at least first and second bearing members with radial clearance of value εr/2 that is of the order of half the mean radial air gap εr of the magnetic bearings being arranged between each of the bearing members and the rotor, and axial clearances εa are provided on either side of the set of bearing members between said set and first and second axial abutment elements secured to the rotor. The first bearing member is mounted directly in a first intermediate support element coaxial with a stator element. The second bearing member is mounted in a second intermediate support element likewise coaxial with the stator element. The intermediate support elements present a plane of contact in a radial plane perpendicular to the axis of the bearing and they are united by a resilient pre-stressed element acting in the axial direction and allowing the intermediate support elements and the bearing members to expand or move apart in the axial direction. Damper means acting in the radial direction are interposed between the intermediate support elements and the stator element.
