Servo transformer energy storage

What is a servo transformer?

This product is an ultra-small-volume three-phase servo electronic transformer specially designed for the mismatch between the grid and the AC servo motor voltage. It has changed the problems of bulky, heat-generating, power-consuming and difficult installation of traditional coil-type transformers. It does not cause pollution to the power grid.

What are the requirements for a servo press supply transformer?

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.

What is servo transformer capacity?

All imported, domestic servo systems; The transformer capacity can be from 05KVA-80KVA, which satisfies the matching of all servo motor voltages. Comparison of Servo electronic transformer and servo voltage stabilizer/traditional transformer:

Does a servo press need energy management?

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.

How much power does a servo press need?

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.

How much power does a 2750 kW servo need?

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.
