Abstract

A measuring device registers the rotation speeed (n) and the imbalance of the rotor. When a minimum speed of the rotor is exceeded, an electrical parameter of the motor is adjusted. The electrical parameter is preferably the voltage (U) and is altered from its extent set for operation to an extent provid for a measurement in such a way that the slope of the characteristic curve of speed-torsion increases accordingly.
