Electromechanical vibrations kit (PT 500.19)

Electromechanical vibrations kit (PT 500.19)

interaction of electromagnetic and mechanical elements of the system

Code PT500.19


  • Asynchronous motors are in widespread use as drive mechanisms.
  • These motors can generate machine vibrations. If there is an asymmetric gap, the circulating magnetic forces induce rotational and bending vibrations.
  • The same applies to partial failure of the electrical windings.
  • In this case, the asymmetrical magnetic field also induces mechanical vibrations.
  • The PT 500.19accessory set features an adjustable centring device to adjust an asymmetrical gap.
  • A winding that can be switched off generates an electromagnetic asymmetry.
  • The display and control unit of the PT 500base system powers the asynchronous motor and permits the speed to be adjusted.
  • The motor is subjected to load by the PT 500.05brake and load unit.
  • The accessory set is mounted on the base plate of the machinery diagnostic base system PT 500.
  • To measure and evaluate the experiment, the computerised vibration analyser PT 500.04is required.
  • It includes all the necessary sensors, a measuring amplifier and analysis software to record the vibration phenomena.
