<p>The drive has an electric motor serving as a primary drive (1) and acting on a central shaft (2), which stays in connection with a safety brake and/or slide lock (3). A gear wheel stage is provided for transmitting the torque of the primary drive to an eccentric shaft (5) of a press. Another electric motor (6) is engaged at an output of the gear wheel stage and is controllable with the torque that is directed opposite to the torque of the primary drive, where the later electric motor is designed as controllable servomotor.</p> |
