Product Details


Technical Description 
 
Asynchronous motors are in widespread use as drive mechanisms. They too 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 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 bse 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 measurement amplifier and analysis software to record the vibration phenomena.
 
Learning Objectives / Experiments

- Influence of the gap on vibration behaviour
- Influence of electromagnetic asymmetry on vibration
  behaviour
- Influence of the load on the level of vibration
- Influence of the gap on electromagnetic losses and
  efficiency
- Influence of speed on vibration behaviour
- Understanding and interpreting frequency spectra
- Use of a computerised vibration analyzer
In conjunction with a current measuring probe:
- Measurement of current consumption per phase

Features
