Zusammenfassung:	The invention relates to a diagnostic method and apparatus for detecting in advance the wear of rotatable components in vacuum pumps, said pumps comprising gas pumping stages formed by rotor disks (113, 114) secured to a rotatable shaft (123) driven by an electric motor, wherein a warning signal for either a pre-alarm or an alarm wear condition is generated when predetermined wear conditions are reached, by expanding the signal from an accelerometer in contact with the vacuum pump into a Fourier spectrum.
