    摘要: Rotating machine vibration monitoring process for detecting degradations within a rotating machine comprising an output axle fitted with magnetic bearings, said magnetic bearings comprising at least a position sensor and at least a magnetic actuator, the process comprising the following steps:
    - defining (1) a set of excitations that does not destabilizes the rotating machine,
    - injecting (2) the set of excitations in the rotating machine through the magnetic actuators and measuring (3) the response of the rotating machine
    - checking (7) whether the response verifies at least one predefined criterium,
    - if it is not the case, adjusting (8) the properties of the set of excitations and resuming the process at the injection step,
    - if the response verifies the at least one criterium, determining (9) at least one condition indicator based on the response measured,
    - determining (10) if an alarm is to be triggered based on the condition indicator determined.

    摘要: A permanent magnet rotor shaft assembly (100) for a high speed electrical machine comprises a permanent magnet cylindrical core (101) having a longitudinal axis, the cylindrical core (101) being axially compressed by first and second end shafts (102A, 102B) and being radially compressed by a sleeve (104) made of a non-magnetic high strength metal. At least one (102A) of the first and second end shafts (102A, 102B) comprises, in its portion facing the cylindrical core (101), a central shoulder head (103A) which cooperates with a mating central recess (106A) made in a central portion of a front face of the cylindrical core (101).
    An easy concentric alignment of the first and second end shafts (102A, 102B) with the permanent magnet cylindrical core (101) is allowed while inserting the sleeve (104) and the stiffness of the assembled set is enhanced.
