Dynamic characterization of electrospindles is necessary to ensure long life, reliability and high-tech performance required in many industrial applications. Many diagnostic approaches have been developed with regard to fault detection and dynamic characterization of rotating machinery. Here, an optimized set-up of a measurement system based on electro-optical sensors is proposed for performing vibration tests on electrospindle rotors. A complete, dynamic characterization of the rotor is obtained through modelling and accurate measurements of shaft vibrations are performed to trace vibration modes of the rotor. The proposed measurement set-up can be used to support the design optimization of electrospindles in order to increase quality standards.

Abstract
Dynamic characterization of electrospindles is necessary to ensure long life, reliability and high-tech performance required in many industrial applications. Many diagnostic approaches have been developed with regard to fault detection and dynamic characterization of rotating machinery. Here, an optimized set-up of a measurement system based on electro-optical sensors is proposed for performing vibration tests on electrospindle rotors. A complete, dynamic characterization of the rotor is obtained through modelling and accurate measurements of shaft vibrations are performed to trace vibration modes of the rotor. The proposed measurement set-up can be used to support the design optimization of electrospindles in order to increase quality standards.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
