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 method for filtering at least one signal to be filtered. The filtering being determined based on measurements representing the movement of a rotating shaft. The method includes defining at least one characterisation indicator of the rotating shaft. The characterisation indicator being obtained from a frequency analysis of the behaviour of the rotating shaft (step 120). The method includes determining a filtering template as a function of the characterisation indicator (step 130) and applying the filtering template to said signal to be filtered (step 140).

Abstract: A control system (15) for controlling a full bridge converter to compensate the reactive power consumed by an inductive position sensor for a rotor of an electrical machine supported by at least one active magnetic bearing is proposed. The inductive position sensor is supplied by an alternating current source. The control system (15) includes a phase shift determining means (26) to determine a phase shift (SP) between a supply voltage (VS) and a supply current (IS) delivered by the source. A first control loop (22) controls the amplitude (AC) of a control signal (SC) from the phase shift (SP). A second control loop (23) controls the phase of the control signal (SC). A third control loop (24) controls a voltage reference (VR). A controlling means (25) controls a full bridge converter according to the control signal (SC).
