Abstract
A method and a system for acquiring a vibratory signal for troubleshooting a rotary motor, including: an input receiving a temporal vibratory signal of the motor and at least one current rotational speed of at least one shaft of the motor, and a sampling mechanism sampling the temporal vibratory signal in real time with at least one sampling signal synchronised with the at least one current rotational speed thus generating a corresponding synchronous vibratory signal.

10. A system for acquiring a vibratory signal for troubleshooting a rotary motor, comprising:
-
input means for receiving a temporal vibratory signal of said motor and at least one current rotational speed of at least one shaft of said motor; and sampling means for sampling of said temporal vibratory signal in real time with at least one sampling signal synchronised with said at least one current rotational speed thus generating a corresponding synchronous vibratory signal, said sampling signal being configured with a predefined maximum harmonic ratio and a predefined sampling ratio. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)
