Servo Presses represent the most interesting innovation in Metal Forming within the last decade. The servo electric presses are based on permanent magnet motor & drives offer to the end user the chance to optimize its production process tools and automation.
Mechanical and Hydraulic Presses continue to represent the more valid solution in many applications. Servo Presses allow to optimize production processes, tool and automation with significant benefits on the whole investment.
OMERA have developed the Hydraulic –SERVO PRESS
The basic concept involves a hydraulic high torque motor which drives the crankshaft; direction and speed are controlled by means of an axial piston pump operating in close circuit. Axial piston pump rotates at constant speed, thus it is possible to use a flywheel as Energy Storage in order to remove power peaks and supply a large amount of Kinematic Energy.
