Compared to a conventional mechanical press, a servo press achieves a significant improvement in production efficiency while maintaining a high energy conservation ratio. The soft touch when the punch comes in contact with the material determines longer die life, without major compromises in terms of productivity. For example, if a S-curve deceleration on a Direct Servo Former is set to 100% at 5,5 mm above BDC, it will enable a reduction in the contact speed to 10% of that of a mechanical press at 4,5 mm above BDC.
The DSF® Technology, based on AIDA independently developed servo motors with low speed, high torque characteristics, offers unmatched performance in metalforming applications. The DSF® Servo System Package not only includes servo motors designed specific for press work ally for but also incorporates AIDA developed power supplies, amplifiers, motion control software and energy management and recovery system.
AIDA has developed an energy control architecture that replaces the mechanical energy of a flywheel with the electrical energy of a capacitor bank. During press deceleration, the electricity is returned to the capacitors. The peak of electrical power required during the forming phase is partly supplied by the electrical energy previously stored in the capacitors, leading to a smaller factory power source capacity comparable to that of a mechanical press. Aside from lowering investment costs by requiring a smaller primary power source capacity, energy is regenerated and returned to the capacitors, which lowers operational costs and conserves electricity.
