Electromechanical Vibrations Kit PT 500.19

Electromechanical Vibrations Kit

Type: PT 500.19
Name: Electromechanical Vibrations Kit
Categorie:
PT 500.19 - A product from the GUNT 2E range
Technical Description

  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 500.19 accessory set features an adjustable centering 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 500 base system powers the asynchronous motor and permits the speed to be adjusted. The motor is subjected to load by the PT 500.05 brake and load unit.
 
  The accessory set is mounted on the base plate of  the machinery diagnostic base system PT500.
  To measure and evaluate the experiment, the computerised vibration analyser PT 500.04 is required. It includes all the necessary sensors, a measuring amplifier and analysis software to record the vibration phenomena.
