Abstract
Provided is a low-cost servo press promoting energy saving by driving a press machine by a driving system suited for the magnitude of a load on a worked object. It includes a first motor coupled to a slide drive shaft to ascend/descend a slide, a second servo motor driving a flywheel, a clutch coupling/decoupling the second servo motor to/from the slide drive shaft, and a press controller controlling rotation of the first and second servo motors and coupling/decoupling of the clutch. The press controller controls to decouple the clutch when the press is small-loaded, thereby ascending/descending the slider by driving the first servo motor, and to couple the clutch when the press is large-loaded, thereby ascending/descending the slider by driving the first and second servo motors.
