Abstract
An internal vibratory device for compacting a casting compound includes a vibratory unit having an electric motor, an electronic unit electromechanically coupled to the vibratory unit for controlling the electric motor via a hose connection, and a power supply unit for electrically supplying power to the electronic unit and the electric motor. The electric motor can be controlled by the electronic unit for a short time such that a critical operating state, in particular a low power state of the power supply, can be indicated via a change in its rotational speed.
