Abstract
A press drive device includes a connecting rod with input and output ends. A drive shaft mounts to rotate about a shaft axis and includes a connecting rod bearing in eccentric relation to the shaft axis. The input end mounts on the connecting rod bearing. At least first and second drive housings are provided on axially opposite sides of the connecting rod bearing. The drive shaft projects into both drive housings. A motor mounts in at least one of the drive housings and includes a stator rotationally fixed to a drive housing peripheral wall located coaxially around the shaft axis. A rotor supported by a rotor hub is arranged radially within the stator with mounting space between the shaft axis and the rotor for possibly mounting a braking device.
