Abstract

The invention relates to a method and to an apparatus for vibration compensation in a piston compressor, the piston compressor of which is driven by means of a crankshaft by a three-phase motor controlled by a frequency converter, wherein the current position the crankshaft of the piston compressor is determined, and based on this the frequency converter, a torque (MM) for the three-phase motor is predetermined, which torque follows the load torque (ML) of the piston compressor in order to reduce the vibration stimulation of the entire piston compressor.
