BaumüllerInsights
The following is an example of an actual DC link unit provided to illustrate the specific advantages of DC links in operation. The Baumüller DC link capacitance unit for the servo controllers of the b maXX 5000 series allow the buffer storage of the braking energy required during the operation of the servo motor. This energy can then be released again for later acceleration processes. This reduces the energy consumption of the overall process, thereby reducing costs in very appreciable way. There are also other advantages, such as:
- Leveling the peak load: This offers a major cost advantage. The reason lies in the framework agreements usually concluded with energy supply companies. High consumption peaks raise the prices of such agreements. By using DC links, energy can be held in reserve to mitigate the peak loads. This reduces costs relative to the individual electricity supply company.
- Lower thermal radiation: Increased space requirements also mean added costs. By lowering thermal radiation, cooling units can be used with more compact designs, which saves space.
- Further space savings: The control cabinet and feed unit can also be designed to be smaller, freeing up additional space.
