Abstract
The invention relates to a mechanical metal-forming machine which comprises a drive shaft, a flywheel drive with a flywheel, an auxiliary drive and a coupling, wherein the flywheel drive drives the metal-forming machine at least intermittently, wherein the flywheel is coupled for this purpose to the drive shaft via the coupling and wherein the auxiliary drive is designed as a servo motor and drives the drive shaft. A rotor of the auxiliary drive is permanently connected to the drive shaft in a torque-proof manner for this purpose and the flywheel is coupled to the rotor of the auxiliary drive by means of the coupling for this purpose, in order to drive the drive shaft via said rotor.
