NTC-13.09.14 “Dynamic rotor balancing”

The training laboratory system allows to investigate the simplest ways of dynamic rotor balancing, determinate imbalances of rotating links and eliminate rotor imbalance, using correction masses.

Structurally, the stand consists of a laboratory unit and 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.
