- a laboratory unit;
- a control unit.
The installation is a steel base with a swinging platform for installing a twin-shaft asynchronous motor. Disks are mounted on the engine with the possibility of mounting additional masses on them as an imbalance. The role of the investigated object is performed by the rotor of the engine with disks. The engine is controlled by the control unit through a frequency converter. As a sensitive element, a Hall sensor is used, which records platform vibrations that occur at resonant frequencies.
