A transformer with a minimum rated power of 2000 kVA is required. For a complete energy management, the drive system of the press example is expanded to include three kinematic energy storage devices with a maximum power of 1000 kW. As a consequence, it is possible to keep the alternat-ing component of the power in the servo press drive sys-tem.
For a servo press without energy management, the mechanical power to be output by the motor – as well as the power loss of the electric system – must always be completely covered by the infeed and the line supply.
The supply transformer must also be correspondingly larger; and in this particular case, it must have a minimum 1000 kVA rating. When compared to a servo press without any type of energy management, partial buffering of the kinetic energy reduces the load peaks that impact the line supply.
This means that the tech-nological advantages of servo presses – their far higher flexibility and production quality as well as their signifi-cantly higher productivity of the footprint used – can be utilized to achieve the most cost effective solution.
For a mechanical efficiency of 92 %, for 2750 kW forming power, servos with a minimum drive power of 3000 kW are required. For conventional methods, these types of motion tasks are solved using cams and higher order polynomial func-tions, and little or no emphasis is placed on the energy related aspects.
