Abstract: Rotating machine vibration monitoring process for detecting degradations within a rotating machine providing an output axle fitted with magnetic bearings, the magnetic bearings having at least a position sensor and at least a magnetic actuator, the process provides the following steps: 1) defining a set of excitations that does not destabilizes the rotating machine, 2) injecting the set of excitations in the rotating machine through the magnetic actuators and 3) measuring the response of the rotating machine checking whether the response verifies at least one predefined criterium, 4) if it is not the case, adjusting the properties of the set of excitations and resuming the process at the injection step, 5) if the response verifies the at least one criterium, determining at least one condition indicator based on the response measured, 6) determining if an alarm is to be triggered based on the condition indicator determined.

Abstract: A system for compensating for the stresses applied to a bearing that rotatably supports a rotor shaft of a rotating machine relative to a stator of the machine. The system provides at least one sensor for measuring an input signal positioned on an element of the bearing, a module for acquiring the input signal configured to convert the input signal into a value of the deformation applied to the rolling bearing, a module for determining a compensation signal as a function of the deformation value, and an amplifier module configured to control a magnetic actuator rotatably supporting the shaft of the rotor and including at least one electromagnet, the amplifier module being configured to convert the compensation signal into a voltage signal transmitted to the electromagnet of the magnetic actuator, the magnetic actuator being configured to exert a force on the rotor shaft as a function of the voltage signal.
