Abstract
A press drive device (21) includes a connecting rod (49) with input (48) and output ends (50). A drive shaft (35) is mounted to be rotatable about a shaft axis W and includes a connecting rod bearing (46) that is eccentric in relation to the shaft axis W. A drive unit (77) includes a driving motor (30) and a planetary gear set (76) to drive the drive shaft (35). A gear output (79) connects to the drive shaft (35), and a gear input (78) connects to a motor shaft (73). The driving motor (30) includes a rotor (66) connected in a rotationally fixed manner to the motor shaft (73) via a rotor hub (67). The rotor (66) is concentric to the motor shaft creating mounting space between the motor shaft (73) and the rotor (66) and designed to arrange a braking device (31) therein.
